time context in case study meaning

How To Write Time Context in Case Study (With Examples)

An impressive case study clearly describes the important facts and details about the issue it analyzes. One of these details that must be considered is the time period when this issue happened. This is specified in the portion of the case study called the Time Context , or “Konteksto ng Panahon ” in Filipino. 

Writing the Time Context of the case study requires careful analysis and decision-making, making it quite challenging for some students. For this reason, this article provides a comprehensive guide on how to write this portion and some examples that you may use as a reference.

• What Is Time Context in a Case Study? 

Why Should I Write the Time Context of My Case Study?

1. identify when the problem of your case study arose, 2. specify the exact period that you are going to analyze, 3. explain your indicated time frame, 1. ensure the time context is clear and not too broad, 2. creating a timeline is optional, what is time context in a case study.

The Time Context, which is located at the beginning of the case study, tells the reader the time during which the problem of the study occurred. In other words, it indicates the “scope” of your analysis in terms of the time period. 

This is analogous to the “setting” of a short story. The setting of a story tells you when it happened. If you imagine your case study as a short story, the time context is its “setting.” 

This portion allows your readers to determine exactly the problem you are referring to by indicating a vital detail: the time when it happened. 

Suppose that your study’s problem revolves around the decline in annual sales of a certain firm. If  the firm experienced a decline in sales in different periods, the readers will have a hard time figuring out which one you’re referring to (e.g., are you referring to the year the sales declined in 2008, 2010, or 2020?) By indicating the time context, this ambiguity is resolved. 

Furthermore, this portion makes your analysis more focused by indicating the specific period where your analysis is bounded. For instance, If your time context is only the first quarter of 2020, then you are not expected to analyze the events that happened or factors that emerged during the periods beyond or even before your selected time context.

How To Write Time Context in a Case Study

Now that you have an idea of the time context, it’s time to write it. Follow the steps below to learn how to write one.

Research the history of your case study’s subject (i.e., the firm/organization) to help you identify the time when its problem arose. This “time” can be a year (e.g., 2020), a month (December 2020), a quarter (Q2 of 2020), or a day (December 1, 2020). 

After you figure out the time when the problem of the firm or organization emerged, think about how long the problem continued to persist. The period from the date the problem arose to the date it was resolved is the time context of your study.

Suppose the firm’s sales started to decline during the first quarter of 2008. If this problem was resolved eventually in the last quarter of 2008, then the time context of your case study is the year 2008. 

If the problem of your case study is happening in the present, then the time context of your case study is the current year. It implies that your analysis will revolve around the current year’s events.

Once you have figured out your case study’s time context, you may now indicate it in your manuscript. You may add supporting details by explaining what happened during that period. 

Most case studies explicitly indicate the time period in this portion without including any explanation.  Although the justification for your selected time context is optional, it is advisable to show one to make this portion more comprehensive.

Examples of Time Context in a Case Study

Case Study Topic: An analysis of how Jollibee Foods Corporation (JFC) handled massive public criticism during the  “Toweljoy” incident wherein one of their customers received an improperly prepared fried chicken that violated the Food Safety Act. 

Time Context: The incident happened in June 2019. JFC responded by temporarily closing for three days the branch where the incident occurred and releasing an official statement acknowledging the issue. The incident became a trending topic days after it happened.

The example above provides a clear timeframe that indicates the coverage of the analysis , which is an event that took place in June 2019. Furthermore, it elaborates the indicated time context by briefly describing what happened during that period.

Case Study Topic: Xelon Pastries struggles to accommodate a large volume of orders due to the holiday season. The management believes that the current number of staff and supplies are insufficient to meet the increase in demand.  Failure to meet the overwhelming customer demand might lead to a loss of profit opportunities. 

Time Context: Xelon Pastries has to accommodate a notable 15% increase in daily orders in December 2015. It is expected that the volume of orders will further increase as the Christmas season approaches. 

Note how the example above provides a specific date during which the business faced the problem (i.e., December 2015). This implies that the analysis will be limited only to the said time period. In other words, the large volume of orders during other “holiday seasons” (e.g., December 2014) and the firm’s condition during the said periods will not be considered in the analysis.

Case Study Topic: Netflix Inc. is struggling to keep up with the increasing market competition after it lost an estimated 200,000 subscribers and experienced a decrease in its market value with a decline in shares of 35%.  Time Context: The first quarter of 2022 is a negative turning point for Netflix Inc. as it struggles with a declining subscriber level due to a variety of reasons, including an increase in “pay-to-watch” platforms and the company’s exit from the Russian market because of the Ukrainian-Russian conflict.

Tips and Warnings

For instance, indicating that your Case Study’s Time Context is “the present year” is too broad since readers have no clue whether you’re referring to the year they are reading your case study or the year when it was published. So, it is better to make it more specific such as “the year 2017”. Furthermore, if you think the problem only occurred in a particular period of that year, make it more specific by indicating the quarter or the month (e.g., Q1 of 2017, August 2017).

You may also present your case study’s Time Context using a timeline. A timeline lists important events throughout the problem’s duration. It’s a sequence of events that happened between the date the problem emerged up to the date it was solved (or present date).

To make a timeline, state the date (or span of periods) when a specific event happened. This event must be relevant to your case study’s problem. Afterward, provide a brief description of what happened during that period. Do this approach for every “sub-events” of your timeline.

Note that using a timeline is optional but you can use it to make this part more detailed.

Here is an example of a case study that presents its Time Context using a timeline:

Case Study Topic: Despite Netflix being the world’s leading streaming platform, it experienced slow revenue growth in early 2022 because of the following:

• The increasing saturation of the “pay-for-view” market
• Ukrainian-Russian conflict
• Stagnant subscriber growth
• Easing pandemic restrictions

Time Context of the Case Study: 

January 2022 – Investors are cautious of the slow growth of Netflix Inc. leading to a tail-off of about $45 billion in market value and 20% in shares. 

January – March 2022 – Netflix Inc. lost an estimated 200,000 subscribers and a decline of 6.4% in its Quarter I net profit.

March 06 – 07, 2022 – Netflix Inc. halted its operations in Russia. This is a response to the worsening crisis due to the Ukrainian-Russian conflict. This leads to a loss of about 700,000 paid subscribers in the region.

April 19, 2022 – Netflix Inc. released a note to its shareholders. It states some factors that contribute to its stagnant revenue growth. These include the following:

• 100 million unpaid subscribers that enjoy shared household accounts
• Increasing market competition 
• Macroeconomic factors including slow economic growth and rising inflation.

April – May 2022 – Netflix’s competitors HBO (and HBO Max) recorded an increase of 3 million subscribers. Meanwhile, Disney Plus garnered more than 7.9 million subscribers. These happened shortly after Netflix lost a significant number of subscribers.

May 17, 2022 – 150 US-based Netflix employees were laid off as a cost-cutting solution to the company’s decline in revenues.

Business Case Analysis Format and Guidelines for Students

This Case Analysis Guideline will help you to have an idea of how to analyze a Business case properly. It will also give you pointers on how to construct and what to include in the different parts of your Case Analysis from the Point of View, Problem Statement, down to the decision-making, and Plan of Action.

May this post be of help to all of you, so you can come up with a better analysis of your group’s homework such as thesis or projects?

I. Point of View

The Point of View refers to the perspective of the decision-maker or person who is in the position to make the final recommendations as mentioned in the case.

For example, the problem is related to the manufacturing division. It can be about Engineering, manufacturing processes, quality assurance, and warehousing. The possible decision-maker or point of view is the Vice President of the Manufacturing division.

If the concern or problem is related to product quality which is under a Quality Department within the manufacturing division,  then it is possible to put the ‘Manager of Quality Department’ at the Point of View.

II. Time Context

The Time Context is the time in the case when you will start your analysis. It can be an imaginary time or the last-mentioned date in the case. Make sure that you can justify the reason behind your given time context. Because if your stated time is not relevant, it is possible that your analysis is also not relevant.

Assuming that the problem arises during the summer / dry season in the Philippines. You cannot put June to November in the time context as it is usually the rainy/wet season in PH.

If the problem arises in 2021, you can use that year in time context. For example, ‘First Quarter of 2021’ or ‘February 2021.’

III. Statement of the Problem

The Statement of the Problem defines the perceived problem in the case which becomes the subject of the analysis. You can present this in declarative or in question format.

For example: How to expand the business of Company A while in the middle of the current situation of the food industry.

IV. Statement of the Objectives

The Statement of the Objectives are goals that the case analysis hopes to achieve. It should basically satisfy the test of SMART (Specific, Measurable, Attainable, Realistic, and Time-bound)

For example: To improve the company’s performance in terms of product quality in 12 months. Or to increase the company’s sales for its dog food product lines in 6 months.

IV. Areas of Consideration

For the areas of consideration in your case study, you have to state the internal and external environment of the company/firm through SWOT (Strengths, Weaknesses, Opportunities, and Threats) Analysis.

You can indicate in the internal environment the facts relating to the company’s financial situation, manufacturing, marketing, and human resources.

For example, does the business have a high employee turnover rate? Does the business’ revenue continuously increase year after year? How about product quality, can it keep up with the industry competition? You should focus on the factors that can help solve the issues and problems that the business is facing .

For the external environment, indicate the economic situation of the city or country. If the government policy affects your business then you can also state it. Indicate here also your competition which company it is or which product. If your chosen company sells dog food or mobile phone, state your competitor.

Now that you have the list of the internal and external environments. You should now list your company’s Strengths, Weaknesses, Opportunities, and Threats.

Under ‘Strengths,’ of course, depending on what is stated in the case. You can indicate if the company is prominent in the industry, awards such as ‘Best Manpower Agency for 10 years,’ ‘Best Hotel in terms of service.’

For ‘Weakness,’ include if the company has a high manpower turnover ratio, lowest quality in the market, and low budget for marketing/advertisement.

Under Opportunities, indicate if the country the company is located in a ‘Free Trade Zone,’ rising population which can equate to increasing product consumption. For example, increasing toothpaste consumption. The Philippine Government has a build build build program which means they will need an increase in cement usage.

VI. Assumptions

The Assumptions are the factors that are not clear or not specifically stated in the case. You need to clarify these factors and state them as assumptions to limit the analysis.

In layman’s terms, you will list in the Assumptions the boundaries of your analysis. It will also help the panelist to understand the reason behind the items you list in your case analysis.

VII. Alternative Courses of Action (ACA)

The Alternative Courses of Actions (ACAs) are the possible solutions to the identified problem. Each of the ACA must stand alone and must be able to solve the stated problem and achieve the objectives. The ACA must be mutually exclusive. In this regard, the student must choose an ACA to the exclusion of the others.

Also, you have to analyze each ACA in the light of the SWOT analysis and assumptions that is if there are any. You have to state clearly the advantages and disadvantages of each ACA. If the case contains enough information or data. Your stated advantages and disadvantages should be supported quantitatively to minimize bias.

VIII. Analysis of ACAs

The analysis of ACAs will state the list of advantages and disadvantages of each alternative course of action.

I have here examples of the courses of action. Again, these ACAs should be mutually exclusive and should solve the issues of the company. If the ACAs are somewhat related to each other, it is best to combine them and then think of a new one that is totally independent.

ACA 1. Increasing the Salary of the Employees

• Advantages of this course of action
• Disadvantages of this course of action

ACA 2. Reduce the Price of the Products Sold

ACA 3. Buyout the Competition

• Disadvantages

IX. Conclusion/Recommendation

After the analysis of the different Alternative Courses of Action (ACAs), you can now come up with the conclusion, recommendations, and decisions. You do not need to repeat the analysis which you have done in the ACA section of the analysis.

To make this part clearer, it is best to come up with a decision matrix similar to the photo.

Decision Matrix Sample

• 1 – Least Favorable
• 2 – Favorable
• 3 – Most Favorable

Here are the examples of criteria that you can use in the decision matrix.

• Ease of Implementation – refers to the effort required to implement the ACA, the least number of people involved or lesser process in implementing the ACA is the highest score
• Time Frame – This is the time required to implement the ACA, the highest score means the least amount of time needed
• Cost-Efficient – This is the amount of capital requirement, the highest score means the least amount of capital needed to implement the task

Recommendation:

Based on the decision matrix, ‘ACA 3 which is Buying out the competition is the best course of action to solve the problem.

X. Plan of Action

The Plan of Action outlines the series of actions to be undertaken to implement the adopted ACA. The plan of action should reflect, the list of activities, the person in charge, the time frame, and the budget to implement the ACA.

To ensure that you have done the analysis comprehensively, it would be best to program the plan according to the basic functional areas. You should present the plan by having column headings for activity, person/unit responsible/ time frame, and budget.

*There you have it guys! May this business case analysis format and guidelines will be able to help students like you in coming up with a logical solution to business-related cases that your teacher gave your group. Good luck!!!

Case studies

Case studies are essential to qualitative research , offering a lens through which researchers can investigate complex phenomena within their real-life contexts. This chapter explores the concept, purpose, applications, examples, and types of case studies and provides guidance on how to conduct case study research effectively.

Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue. Let's provide a basic definition of a case study, then explore its characteristics and role in the qualitative research process.

Definition of a case study

A case study in qualitative research is a strategy of inquiry that involves an in-depth investigation of a phenomenon within its real-world context. It provides researchers with the opportunity to acquire an in-depth understanding of intricate details that might not be as apparent or accessible through other methods of research. The specific case or cases being studied can be a single person, group, or organization – demarcating what constitutes a relevant case worth studying depends on the researcher and their research question .

Among qualitative research methods , a case study relies on multiple sources of evidence, such as documents, artifacts, interviews , or observations , to present a complete and nuanced understanding of the phenomenon under investigation. The objective is to illuminate the readers' understanding of the phenomenon beyond its abstract statistical or theoretical explanations.

Characteristics of case studies

Case studies typically possess a number of distinct characteristics that set them apart from other research methods. These characteristics include a focus on holistic description and explanation, flexibility in the design and data collection methods, reliance on multiple sources of evidence, and emphasis on the context in which the phenomenon occurs.

Furthermore, case studies can often involve a longitudinal examination of the case, meaning they study the case over a period of time. These characteristics allow case studies to yield comprehensive, in-depth, and richly contextualized insights about the phenomenon of interest.

The role of case studies in research

Case studies hold a unique position in the broader landscape of research methods aimed at theory development. They are instrumental when the primary research interest is to gain an intensive, detailed understanding of a phenomenon in its real-life context.

In addition, case studies can serve different purposes within research - they can be used for exploratory, descriptive, or explanatory purposes, depending on the research question and objectives. This flexibility and depth make case studies a valuable tool in the toolkit of qualitative researchers.

Remember, a well-conducted case study can offer a rich, insightful contribution to both academic and practical knowledge through theory development or theory verification, thus enhancing our understanding of complex phenomena in their real-world contexts.

What is the purpose of a case study?

Case study research aims for a more comprehensive understanding of phenomena, requiring various research methods to gather information for qualitative analysis . Ultimately, a case study can allow the researcher to gain insight into a particular object of inquiry and develop a theoretical framework relevant to the research inquiry.

Why use case studies in qualitative research?

Using case studies as a research strategy depends mainly on the nature of the research question and the researcher's access to the data.

Conducting case study research provides a level of detail and contextual richness that other research methods might not offer. They are beneficial when there's a need to understand complex social phenomena within their natural contexts.

The explanatory, exploratory, and descriptive roles of case studies

Case studies can take on various roles depending on the research objectives. They can be exploratory when the research aims to discover new phenomena or define new research questions; they are descriptive when the objective is to depict a phenomenon within its context in a detailed manner; and they can be explanatory if the goal is to understand specific relationships within the studied context. Thus, the versatility of case studies allows researchers to approach their topic from different angles, offering multiple ways to uncover and interpret the data .

The impact of case studies on knowledge development

Case studies play a significant role in knowledge development across various disciplines. Analysis of cases provides an avenue for researchers to explore phenomena within their context based on the collected data.

This can result in the production of rich, practical insights that can be instrumental in both theory-building and practice. Case studies allow researchers to delve into the intricacies and complexities of real-life situations, uncovering insights that might otherwise remain hidden.

Types of case studies

In qualitative research , a case study is not a one-size-fits-all approach. Depending on the nature of the research question and the specific objectives of the study, researchers might choose to use different types of case studies. These types differ in their focus, methodology, and the level of detail they provide about the phenomenon under investigation.

Understanding these types is crucial for selecting the most appropriate approach for your research project and effectively achieving your research goals. Let's briefly look at the main types of case studies.

Exploratory case studies

Exploratory case studies are typically conducted to develop a theory or framework around an understudied phenomenon. They can also serve as a precursor to a larger-scale research project. Exploratory case studies are useful when a researcher wants to identify the key issues or questions which can spur more extensive study or be used to develop propositions for further research. These case studies are characterized by flexibility, allowing researchers to explore various aspects of a phenomenon as they emerge, which can also form the foundation for subsequent studies.

Descriptive case studies

Descriptive case studies aim to provide a complete and accurate representation of a phenomenon or event within its context. These case studies are often based on an established theoretical framework, which guides how data is collected and analyzed. The researcher is concerned with describing the phenomenon in detail, as it occurs naturally, without trying to influence or manipulate it.

Explanatory case studies

Explanatory case studies are focused on explanation - they seek to clarify how or why certain phenomena occur. Often used in complex, real-life situations, they can be particularly valuable in clarifying causal relationships among concepts and understanding the interplay between different factors within a specific context.

Intrinsic, instrumental, and collective case studies

These three categories of case studies focus on the nature and purpose of the study. An intrinsic case study is conducted when a researcher has an inherent interest in the case itself. Instrumental case studies are employed when the case is used to provide insight into a particular issue or phenomenon. A collective case study, on the other hand, involves studying multiple cases simultaneously to investigate some general phenomena.

Each type of case study serves a different purpose and has its own strengths and challenges. The selection of the type should be guided by the research question and objectives, as well as the context and constraints of the research.

The flexibility, depth, and contextual richness offered by case studies make this approach an excellent research method for various fields of study. They enable researchers to investigate real-world phenomena within their specific contexts, capturing nuances that other research methods might miss. Across numerous fields, case studies provide valuable insights into complex issues.

Critical information systems research

Case studies provide a detailed understanding of the role and impact of information systems in different contexts. They offer a platform to explore how information systems are designed, implemented, and used and how they interact with various social, economic, and political factors. Case studies in this field often focus on examining the intricate relationship between technology, organizational processes, and user behavior, helping to uncover insights that can inform better system design and implementation.

Health research

Health research is another field where case studies are highly valuable. They offer a way to explore patient experiences, healthcare delivery processes, and the impact of various interventions in a real-world context.

Case studies can provide a deep understanding of a patient's journey, giving insights into the intricacies of disease progression, treatment effects, and the psychosocial aspects of health and illness.

Asthma research studies

Specifically within medical research, studies on asthma often employ case studies to explore the individual and environmental factors that influence asthma development, management, and outcomes. A case study can provide rich, detailed data about individual patients' experiences, from the triggers and symptoms they experience to the effectiveness of various management strategies. This can be crucial for developing patient-centered asthma care approaches.

Other fields

Apart from the fields mentioned, case studies are also extensively used in business and management research, education research, and political sciences, among many others. They provide an opportunity to delve into the intricacies of real-world situations, allowing for a comprehensive understanding of various phenomena.

Case studies, with their depth and contextual focus, offer unique insights across these varied fields. They allow researchers to illuminate the complexities of real-life situations, contributing to both theory and practice.

Understanding the key elements of case study design is crucial for conducting rigorous and impactful case study research. A well-structured design guides the researcher through the process, ensuring that the study is methodologically sound and its findings are reliable and valid. The main elements of case study design include the research question , propositions, units of analysis, and the logic linking the data to the propositions.

The research question is the foundation of any research study. A good research question guides the direction of the study and informs the selection of the case, the methods of collecting data, and the analysis techniques. A well-formulated research question in case study research is typically clear, focused, and complex enough to merit further detailed examination of the relevant case(s).

Propositions

Propositions, though not necessary in every case study, provide a direction by stating what we might expect to find in the data collected. They guide how data is collected and analyzed by helping researchers focus on specific aspects of the case. They are particularly important in explanatory case studies, which seek to understand the relationships among concepts within the studied phenomenon.

Units of analysis

The unit of analysis refers to the case, or the main entity or entities that are being analyzed in the study. In case study research, the unit of analysis can be an individual, a group, an organization, a decision, an event, or even a time period. It's crucial to clearly define the unit of analysis, as it shapes the qualitative data analysis process by allowing the researcher to analyze a particular case and synthesize analysis across multiple case studies to draw conclusions.

Argumentation

This refers to the inferential model that allows researchers to draw conclusions from the data. The researcher needs to ensure that there is a clear link between the data, the propositions (if any), and the conclusions drawn. This argumentation is what enables the researcher to make valid and credible inferences about the phenomenon under study.

Understanding and carefully considering these elements in the design phase of a case study can significantly enhance the quality of the research. It can help ensure that the study is methodologically sound and its findings contribute meaningful insights about the case.

Conducting a case study involves several steps, from defining the research question and selecting the case to collecting and analyzing data . This section outlines these key stages, providing a practical guide on how to conduct case study research.

Defining the research question

The first step in case study research is defining a clear, focused research question. This question should guide the entire research process, from case selection to analysis. It's crucial to ensure that the research question is suitable for a case study approach. Typically, such questions are exploratory or descriptive in nature and focus on understanding a phenomenon within its real-life context.

Selecting and defining the case

The selection of the case should be based on the research question and the objectives of the study. It involves choosing a unique example or a set of examples that provide rich, in-depth data about the phenomenon under investigation. After selecting the case, it's crucial to define it clearly, setting the boundaries of the case, including the time period and the specific context.

Previous research can help guide the case study design. When considering a case study, an example of a case could be taken from previous case study research and used to define cases in a new research inquiry. Considering recently published examples can help understand how to select and define cases effectively.

Developing a detailed case study protocol

A case study protocol outlines the procedures and general rules to be followed during the case study. This includes the data collection methods to be used, the sources of data, and the procedures for analysis. Having a detailed case study protocol ensures consistency and reliability in the study.

The protocol should also consider how to work with the people involved in the research context to grant the research team access to collecting data. As mentioned in previous sections of this guide, establishing rapport is an essential component of qualitative research as it shapes the overall potential for collecting and analyzing data.

Collecting data

Gathering data in case study research often involves multiple sources of evidence, including documents, archival records, interviews, observations, and physical artifacts. This allows for a comprehensive understanding of the case. The process for gathering data should be systematic and carefully documented to ensure the reliability and validity of the study.

Analyzing and interpreting data

The next step is analyzing the data. This involves organizing the data , categorizing it into themes or patterns , and interpreting these patterns to answer the research question. The analysis might also involve comparing the findings with prior research or theoretical propositions.

Writing the case study report

The final step is writing the case study report . This should provide a detailed description of the case, the data, the analysis process, and the findings. The report should be clear, organized, and carefully written to ensure that the reader can understand the case and the conclusions drawn from it.

Each of these steps is crucial in ensuring that the case study research is rigorous, reliable, and provides valuable insights about the case.

The type, depth, and quality of data in your study can significantly influence the validity and utility of the study. In case study research, data is usually collected from multiple sources to provide a comprehensive and nuanced understanding of the case. This section will outline the various methods of collecting data used in case study research and discuss considerations for ensuring the quality of the data.

Interviews are a common method of gathering data in case study research. They can provide rich, in-depth data about the perspectives, experiences, and interpretations of the individuals involved in the case. Interviews can be structured , semi-structured , or unstructured , depending on the research question and the degree of flexibility needed.

Observations

Observations involve the researcher observing the case in its natural setting, providing first-hand information about the case and its context. Observations can provide data that might not be revealed in interviews or documents, such as non-verbal cues or contextual information.

Documents and artifacts

Documents and archival records provide a valuable source of data in case study research. They can include reports, letters, memos, meeting minutes, email correspondence, and various public and private documents related to the case.

These records can provide historical context, corroborate evidence from other sources, and offer insights into the case that might not be apparent from interviews or observations.

Physical artifacts refer to any physical evidence related to the case, such as tools, products, or physical environments. These artifacts can provide tangible insights into the case, complementing the data gathered from other sources.

Ensuring the quality of data collection

Determining the quality of data in case study research requires careful planning and execution. It's crucial to ensure that the data is reliable, accurate, and relevant to the research question. This involves selecting appropriate methods of collecting data, properly training interviewers or observers, and systematically recording and storing the data. It also includes considering ethical issues related to collecting and handling data, such as obtaining informed consent and ensuring the privacy and confidentiality of the participants.

Data analysis

Analyzing case study research involves making sense of the rich, detailed data to answer the research question. This process can be challenging due to the volume and complexity of case study data. However, a systematic and rigorous approach to analysis can ensure that the findings are credible and meaningful. This section outlines the main steps and considerations in analyzing data in case study research.

Organizing the data

The first step in the analysis is organizing the data. This involves sorting the data into manageable sections, often according to the data source or the theme. This step can also involve transcribing interviews, digitizing physical artifacts, or organizing observational data.

Categorizing and coding the data

Once the data is organized, the next step is to categorize or code the data. This involves identifying common themes, patterns, or concepts in the data and assigning codes to relevant data segments. Coding can be done manually or with the help of software tools, and in either case, qualitative analysis software can greatly facilitate the entire coding process. Coding helps to reduce the data to a set of themes or categories that can be more easily analyzed.

Identifying patterns and themes

After coding the data, the researcher looks for patterns or themes in the coded data. This involves comparing and contrasting the codes and looking for relationships or patterns among them. The identified patterns and themes should help answer the research question.

Interpreting the data

Once patterns and themes have been identified, the next step is to interpret these findings. This involves explaining what the patterns or themes mean in the context of the research question and the case. This interpretation should be grounded in the data, but it can also involve drawing on theoretical concepts or prior research.

Verification of the data

The last step in the analysis is verification. This involves checking the accuracy and consistency of the analysis process and confirming that the findings are supported by the data. This can involve re-checking the original data, checking the consistency of codes, or seeking feedback from research participants or peers.

Like any research method , case study research has its strengths and limitations. Researchers must be aware of these, as they can influence the design, conduct, and interpretation of the study.

Understanding the strengths and limitations of case study research can also guide researchers in deciding whether this approach is suitable for their research question . This section outlines some of the key strengths and limitations of case study research.

Benefits include the following:

• Rich, detailed data: One of the main strengths of case study research is that it can generate rich, detailed data about the case. This can provide a deep understanding of the case and its context, which can be valuable in exploring complex phenomena.
• Flexibility: Case study research is flexible in terms of design , data collection , and analysis . A sufficient degree of flexibility allows the researcher to adapt the study according to the case and the emerging findings.
• Real-world context: Case study research involves studying the case in its real-world context, which can provide valuable insights into the interplay between the case and its context.
• Multiple sources of evidence: Case study research often involves collecting data from multiple sources , which can enhance the robustness and validity of the findings.

On the other hand, researchers should consider the following limitations:

• Generalizability: A common criticism of case study research is that its findings might not be generalizable to other cases due to the specificity and uniqueness of each case.
• Time and resource intensive: Case study research can be time and resource intensive due to the depth of the investigation and the amount of collected data.
• Complexity of analysis: The rich, detailed data generated in case study research can make analyzing the data challenging.
• Subjectivity: Given the nature of case study research, there may be a higher degree of subjectivity in interpreting the data , so researchers need to reflect on this and transparently convey to audiences how the research was conducted.

Being aware of these strengths and limitations can help researchers design and conduct case study research effectively and interpret and report the findings appropriately.

A case study research paper examines a person, place, event, condition, phenomenon, or other type of subject of analysis in order to extrapolate  key themes and results that help predict future trends, illuminate previously hidden issues that can be applied to practice, and/or provide a means for understanding an important research problem with greater clarity. A case study research paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or more subjects. The methods used to study a case can rest within a quantitative, qualitative, or mixed-method investigative paradigm.

How to Approach Writing a Case Study Research Paper

General information about how to choose a topic to investigate can be found under the " Choosing a Research Problem " tab in the Organizing Your Social Sciences Research Paper writing guide. Review this page because it may help you identify a subject of analysis that can be investigated using a case study design.

However, identifying a case to investigate involves more than choosing the research problem . A case study encompasses a problem contextualized around the application of in-depth analysis, interpretation, and discussion, often resulting in specific recommendations for action or for improving existing conditions. As Seawright and Gerring note, practical considerations such as time and access to information can influence case selection, but these issues should not be the sole factors used in describing the methodological justification for identifying a particular case to study. Given this, selecting a case includes considering the following:

• The case represents an unusual or atypical example of a research problem that requires more in-depth analysis? Cases often represent a topic that rests on the fringes of prior investigations because the case may provide new ways of understanding the research problem. For example, if the research problem is to identify strategies to improve policies that support girl's access to secondary education in predominantly Muslim nations, you could consider using Azerbaijan as a case study rather than selecting a more obvious nation in the Middle East. Doing so may reveal important new insights into recommending how governments in other predominantly Muslim nations can formulate policies that support improved access to education for girls.
• The case provides important insight or illuminate a previously hidden problem? In-depth analysis of a case can be based on the hypothesis that the case study will reveal trends or issues that have not been exposed in prior research or will reveal new and important implications for practice. For example, anecdotal evidence may suggest drug use among homeless veterans is related to their patterns of travel throughout the day. Assuming prior studies have not looked at individual travel choices as a way to study access to illicit drug use, a case study that observes a homeless veteran could reveal how issues of personal mobility choices facilitate regular access to illicit drugs. Note that it is important to conduct a thorough literature review to ensure that your assumption about the need to reveal new insights or previously hidden problems is valid and evidence-based.
• The case challenges and offers a counter-point to prevailing assumptions? Over time, research on any given topic can fall into a trap of developing assumptions based on outdated studies that are still applied to new or changing conditions or the idea that something should simply be accepted as "common sense," even though the issue has not been thoroughly tested in current practice. A case study analysis may offer an opportunity to gather evidence that challenges prevailing assumptions about a research problem and provide a new set of recommendations applied to practice that have not been tested previously. For example, perhaps there has been a long practice among scholars to apply a particular theory in explaining the relationship between two subjects of analysis. Your case could challenge this assumption by applying an innovative theoretical framework [perhaps borrowed from another discipline] to explore whether this approach offers new ways of understanding the research problem. Taking a contrarian stance is one of the most important ways that new knowledge and understanding develops from existing literature.
• The case provides an opportunity to pursue action leading to the resolution of a problem? Another way to think about choosing a case to study is to consider how the results from investigating a particular case may result in findings that reveal ways in which to resolve an existing or emerging problem. For example, studying the case of an unforeseen incident, such as a fatal accident at a railroad crossing, can reveal hidden issues that could be applied to preventative measures that contribute to reducing the chance of accidents in the future. In this example, a case study investigating the accident could lead to a better understanding of where to strategically locate additional signals at other railroad crossings so as to better warn drivers of an approaching train, particularly when visibility is hindered by heavy rain, fog, or at night.
• The case offers a new direction in future research? A case study can be used as a tool for an exploratory investigation that highlights the need for further research about the problem. A case can be used when there are few studies that help predict an outcome or that establish a clear understanding about how best to proceed in addressing a problem. For example, after conducting a thorough literature review [very important!], you discover that little research exists showing the ways in which women contribute to promoting water conservation in rural communities of east central Africa. A case study of how women contribute to saving water in a rural village of Uganda can lay the foundation for understanding the need for more thorough research that documents how women in their roles as cooks and family caregivers think about water as a valuable resource within their community. This example of a case study could also point to the need for scholars to build new theoretical frameworks around the topic [e.g., applying feminist theories of work and family to the issue of water conservation].

Structure and Writing Style

The purpose of a paper in the social sciences designed around a case study is to thoroughly investigate a subject of analysis in order to reveal a new understanding about the research problem and, in so doing, contributing new knowledge to what is already known from previous studies. In applied social sciences disciplines [e.g., education, social work, public administration, etc.], case studies may also be used to reveal best practices, highlight key programs, or investigate interesting aspects of professional work.

In general, the structure of a case study research paper is not all that different from a standard college-level research paper. However, there are subtle differences you should be aware of. Here are the key elements to organizing and writing a case study research paper.

I.  Introduction

As with any research paper, your introduction should serve as a roadmap for your readers to ascertain the scope and purpose of your study . The introduction to a case study research paper, however, should not only describe the research problem and its significance, but you should also succinctly describe why the case is being used and how it relates to addressing the problem. The two elements should be linked. With this in mind, a good introduction answers these four questions:

• What is being studied? Describe the research problem and describe the subject of analysis [the case] you have chosen to address the problem. Explain how they are linked and what elements of the case will help to expand knowledge and understanding about the problem.
• Why is this topic important to investigate? Describe the significance of the research problem and state why a case study design and the subject of analysis that the paper is designed around is appropriate in addressing the problem.
• What did we know about this topic before I did this study? Provide background that helps lead the reader into the more in-depth literature review to follow. If applicable, summarize prior case study research applied to the research problem and why it fails to adequately address the problem. Describe why your case will be useful. If no prior case studies have been used to address the research problem, explain why you have selected this subject of analysis.
• How will this study advance new knowledge or new ways of understanding? Explain why your case study will be suitable in helping to expand knowledge and understanding about the research problem.

Each of these questions should be addressed in no more than a few paragraphs. Exceptions to this can be when you are addressing a complex research problem or subject of analysis that requires more in-depth background information.

II.  Literature Review

The literature review for a case study research paper is generally structured the same as it is for any college-level research paper. The difference, however, is that the literature review is focused on providing background information and  enabling historical interpretation of the subject of analysis in relation to the research problem the case is intended to address . This includes synthesizing studies that help to:

• Place relevant works in the context of their contribution to understanding the case study being investigated . This would involve summarizing studies that have used a similar subject of analysis to investigate the research problem. If there is literature using the same or a very similar case to study, you need to explain why duplicating past research is important [e.g., conditions have changed; prior studies were conducted long ago, etc.].
• Describe the relationship each work has to the others under consideration that informs the reader why this case is applicable . Your literature review should include a description of any works that support using the case to investigate the research problem and the underlying research questions.
• Identify new ways to interpret prior research using the case study . If applicable, review any research that has examined the research problem using a different research design. Explain how your use of a case study design may reveal new knowledge or a new perspective or that can redirect research in an important new direction.
• Resolve conflicts amongst seemingly contradictory previous studies . This refers to synthesizing any literature that points to unresolved issues of concern about the research problem and describing how the subject of analysis that forms the case study can help resolve these existing contradictions.
• Point the way in fulfilling a need for additional research . Your review should examine any literature that lays a foundation for understanding why your case study design and the subject of analysis around which you have designed your study may reveal a new way of approaching the research problem or offer a perspective that points to the need for additional research.
• Expose any gaps that exist in the literature that the case study could help to fill . Summarize any literature that not only shows how your subject of analysis contributes to understanding the research problem, but how your case contributes to a new way of understanding the problem that prior research has failed to do.
• Locate your own research within the context of existing literature [very important!] . Collectively, your literature review should always place your case study within the larger domain of prior research about the problem. The overarching purpose of reviewing pertinent literature in a case study paper is to demonstrate that you have thoroughly identified and synthesized prior studies in relation to explaining the relevance of the case in addressing the research problem.

III.  Method

In this section, you explain why you selected a particular case [i.e., subject of analysis] and the strategy you used to identify and ultimately decide that your case was appropriate in addressing the research problem. The way you describe the methods used varies depending on the type of subject of analysis that constitutes your case study.

If your subject of analysis is an incident or event . In the social and behavioral sciences, the event or incident that represents the case to be studied is usually bounded by time and place, with a clear beginning and end and with an identifiable location or position relative to its surroundings. The subject of analysis can be a rare or critical event or it can focus on a typical or regular event. The purpose of studying a rare event is to illuminate new ways of thinking about the broader research problem or to test a hypothesis. Critical incident case studies must describe the method by which you identified the event and explain the process by which you determined the validity of this case to inform broader perspectives about the research problem or to reveal new findings. However, the event does not have to be a rare or uniquely significant to support new thinking about the research problem or to challenge an existing hypothesis. For example, Walo, Bull, and Breen conducted a case study to identify and evaluate the direct and indirect economic benefits and costs of a local sports event in the City of Lismore, New South Wales, Australia. The purpose of their study was to provide new insights from measuring the impact of a typical local sports event that prior studies could not measure well because they focused on large "mega-events." Whether the event is rare or not, the methods section should include an explanation of the following characteristics of the event: a) when did it take place; b) what were the underlying circumstances leading to the event; and, c) what were the consequences of the event in relation to the research problem.

If your subject of analysis is a person. Explain why you selected this particular individual to be studied and describe what experiences they have had that provide an opportunity to advance new understandings about the research problem. Mention any background about this person which might help the reader understand the significance of their experiences that make them worthy of study. This includes describing the relationships this person has had with other people, institutions, and/or events that support using them as the subject for a case study research paper. It is particularly important to differentiate the person as the subject of analysis from others and to succinctly explain how the person relates to examining the research problem [e.g., why is one politician in a particular local election used to show an increase in voter turnout from any other candidate running in the election]. Note that these issues apply to a specific group of people used as a case study unit of analysis [e.g., a classroom of students].

If your subject of analysis is a place. In general, a case study that investigates a place suggests a subject of analysis that is unique or special in some way and that this uniqueness can be used to build new understanding or knowledge about the research problem. A case study of a place must not only describe its various attributes relevant to the research problem [e.g., physical, social, historical, cultural, economic, political], but you must state the method by which you determined that this place will illuminate new understandings about the research problem. It is also important to articulate why a particular place as the case for study is being used if similar places also exist [i.e., if you are studying patterns of homeless encampments of veterans in open spaces, explain why you are studying Echo Park in Los Angeles rather than Griffith Park?]. If applicable, describe what type of human activity involving this place makes it a good choice to study [e.g., prior research suggests Echo Park has more homeless veterans].

If your subject of analysis is a phenomenon. A phenomenon refers to a fact, occurrence, or circumstance that can be studied or observed but with the cause or explanation to be in question. In this sense, a phenomenon that forms your subject of analysis can encompass anything that can be observed or presumed to exist but is not fully understood. In the social and behavioral sciences, the case usually focuses on human interaction within a complex physical, social, economic, cultural, or political system. For example, the phenomenon could be the observation that many vehicles used by ISIS fighters are small trucks with English language advertisements on them. The research problem could be that ISIS fighters are difficult to combat because they are highly mobile. The research questions could be how and by what means are these vehicles used by ISIS being supplied to the militants and how might supply lines to these vehicles be cut off? How might knowing the suppliers of these trucks reveal larger networks of collaborators and financial support? A case study of a phenomenon most often encompasses an in-depth analysis of a cause and effect that is grounded in an interactive relationship between people and their environment in some way.

NOTE:   The choice of the case or set of cases to study cannot appear random. Evidence that supports the method by which you identified and chose your subject of analysis should clearly support investigation of the research problem and linked to key findings from your literature review. Be sure to cite any studies that helped you determine that the case you chose was appropriate for examining the problem.

IV.  Discussion

The main elements of your discussion section are generally the same as any research paper, but centered around interpreting and drawing conclusions about the key findings from your analysis of the case study. Note that a general social sciences research paper may contain a separate section to report findings. However, in a paper designed around a case study, it is common to combine a description of the results with the discussion about their implications. The objectives of your discussion section should include the following:

Reiterate the Research Problem/State the Major Findings Briefly reiterate the research problem you are investigating and explain why the subject of analysis around which you designed the case study were used. You should then describe the findings revealed from your study of the case using direct, declarative, and succinct proclamation of the study results. Highlight any findings that were unexpected or especially profound.

Explain the Meaning of the Findings and Why They are Important Systematically explain the meaning of your case study findings and why you believe they are important. Begin this part of the section by repeating what you consider to be your most important or surprising finding first, then systematically review each finding. Be sure to thoroughly extrapolate what your analysis of the case can tell the reader about situations or conditions beyond the actual case that was studied while, at the same time, being careful not to misconstrue or conflate a finding that undermines the external validity of your conclusions.

Relate the Findings to Similar Studies No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your case study results to those found in other studies, particularly if questions raised from prior studies served as the motivation for choosing your subject of analysis. This is important because comparing and contrasting the findings of other studies helps support the overall importance of your results and it highlights how and in what ways your case study design and the subject of analysis differs from prior research about the topic.

Consider Alternative Explanations of the Findings Remember that the purpose of social science research is to discover and not to prove. When writing the discussion section, you should carefully consider all possible explanations revealed by the case study results, rather than just those that fit your hypothesis or prior assumptions and biases. Be alert to what the in-depth analysis of the case may reveal about the research problem, including offering a contrarian perspective to what scholars have stated in prior research if that is how the findings can be interpreted from your case.

Acknowledge the Study's Limitations You can state the study's limitations in the conclusion section of your paper but describing the limitations of your subject of analysis in the discussion section provides an opportunity to identify the limitations and explain why they are not significant. This part of the discussion section should also note any unanswered questions or issues your case study could not address. More detailed information about how to document any limitations to your research can be found here .

Suggest Areas for Further Research Although your case study may offer important insights about the research problem, there are likely additional questions related to the problem that remain unanswered or findings that unexpectedly revealed themselves as a result of your in-depth analysis of the case. Be sure that the recommendations for further research are linked to the research problem and that you explain why your recommendations are valid in other contexts and based on the original assumptions of your study.

V.  Conclusion

As with any research paper, you should summarize your conclusion in clear, simple language; emphasize how the findings from your case study differs from or supports prior research and why. Do not simply reiterate the discussion section. Provide a synthesis of key findings presented in the paper to show how these converge to address the research problem. If you haven't already done so in the discussion section, be sure to document the limitations of your case study and any need for further research.

The function of your paper's conclusion is to: 1) reiterate the main argument supported by the findings from your case study; 2) state clearly the context, background, and necessity of pursuing the research problem using a case study design in relation to an issue, controversy, or a gap found from reviewing the literature; and, 3) provide a place to persuasively and succinctly restate the significance of your research problem, given that the reader has now been presented with in-depth information about the topic.

Consider the following points to help ensure your conclusion is appropriate:

• If the argument or purpose of your paper is complex, you may need to summarize these points for your reader.
• If prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the conclusion of your paper to describe your main points and explain their significance.
• Move from a detailed to a general level of consideration of the case study's findings that returns the topic to the context provided by the introduction or within a new context that emerges from your case study findings.

Note that, depending on the discipline you are writing in or the preferences of your professor, the concluding paragraph may contain your final reflections on the evidence presented as it applies to practice or on the essay's central research problem. However, the nature of being introspective about the subject of analysis you have investigated will depend on whether you are explicitly asked to express your observations in this way.

Problems to Avoid

Overgeneralization One of the goals of a case study is to lay a foundation for understanding broader trends and issues applied to similar circumstances. However, be careful when drawing conclusions from your case study. They must be evidence-based and grounded in the results of the study; otherwise, it is merely speculation. Looking at a prior example, it would be incorrect to state that a factor in improving girls access to education in Azerbaijan and the policy implications this may have for improving access in other Muslim nations is due to girls access to social media if there is no documentary evidence from your case study to indicate this. There may be anecdotal evidence that retention rates were better for girls who were engaged with social media, but this observation would only point to the need for further research and would not be a definitive finding if this was not a part of your original research agenda.

Failure to Document Limitations No case is going to reveal all that needs to be understood about a research problem. Therefore, just as you have to clearly state the limitations of a general research study , you must describe the specific limitations inherent in the subject of analysis. For example, the case of studying how women conceptualize the need for water conservation in a village in Uganda could have limited application in other cultural contexts or in areas where fresh water from rivers or lakes is plentiful and, therefore, conservation is understood more in terms of managing access rather than preserving access to a scarce resource.

Failure to Extrapolate All Possible Implications Just as you don't want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings. If you do not, your reader may question the validity of your analysis, particularly if you failed to document an obvious outcome from your case study research. For example, in the case of studying the accident at the railroad crossing to evaluate where and what types of warning signals should be located, you failed to take into consideration speed limit signage as well as warning signals. When designing your case study, be sure you have thoroughly addressed all aspects of the problem and do not leave gaps in your analysis that leave the reader questioning the results.

Writing Tip

At Least Five Misconceptions about Case Study Research

Social science case studies are often perceived as limited in their ability to create new knowledge because they are not randomly selected and findings cannot be generalized to larger populations. Flyvbjerg examines five misunderstandings about case study research and systematically "corrects" each one. To quote, these are:

Misunderstanding 1 :  General, theoretical [context-independent] knowledge is more valuable than concrete, practical [context-dependent] knowledge. Misunderstanding 2 :  One cannot generalize on the basis of an individual case; therefore, the case study cannot contribute to scientific development. Misunderstanding 3 :  The case study is most useful for generating hypotheses; that is, in the first stage of a total research process, whereas other methods are more suitable for hypotheses testing and theory building. Misunderstanding 4 :  The case study contains a bias toward verification, that is, a tendency to confirm the researcher’s preconceived notions. Misunderstanding 5 :  It is often difficult to summarize and develop general propositions and theories on the basis of specific case studies [p. 221].

While writing your paper, think introspectively about how you addressed these misconceptions because to do so can help you strengthen the validity and reliability of your research by clarifying issues of case selection, the testing and challenging of existing assumptions, the interpretation of key findings, and the summation of case outcomes. Think of a case study research paper as a complete, in-depth narrative about the specific properties and key characteristics of your subject of analysis applied to the research problem.

21 Context, Contextualization, and Case-Study Research

Attilia Ruzzene is a postdoctoral researcher at the University of Bergamo. She obtained her first PhD in economics at the University of Torino and a PhD in philosophy at the Erasmus University in Rotterdam. She has been teaching courses on the philosophy of science, economics, and social sciences at the Erasmus University Rotterdam, Witten/Herdecke University, and University of Bologna. Her research currently focuses on a variety of qualitative perspectives for the study of organizational phenomena which include causal-mechanistic reasoning, the practice approach, and visual analysis. She has long lasting interest in issues related to causal inference in case-study research and the use of case-study evidence for policy making.

Whenever contextual conditions influence the occurrence of social phenomena, case studies come to the rescue by improving the accuracy of explanations that are exceedingly general and abstract. Being highly permeable to particulars of the setting in which the phenomenon unfolds, case-study research expresses a sensitivity to context that can be leveraged for understanding how context matters, to what extent, and in what respects. How this capacity of case-study research is effectively leveraged, however, remains in large part a mystery. In this chapter, I address this issue by investigating the way case studies pursue contextualization, that is the conversion of case-specific information into knowledge of context. I distinguish between process tracing and process embedding, suggest that their interplay is at the core of contextualization, and identify the evidentiary principles that govern their joint employment. I further illustrate the specific role process embedding plays vis-à-vis process tracing by drawing on a sample of few case studies on civil war.

1. Introduction

According to some observers of the field, qualitative methods have recently experienced a “renaissance” in several areas of political science ( Bennett & Elman 2007a ; Gerring 2007 ; Mahoney 2007 ). The areas invested by this turn include, but are not limited to, subfields such as comparative politics, international relations, and American politics (Bennet & Elman 2007a). In the early 2000s, a new generation of qualitative studies was born distinguishing itself from previous qualitative works for the broader range of publications, for a higher methodological awareness, and for a closer association with quantitative methods and formal modeling. This remarkable surge of the qualitative is driven by several factors. First is the recognition that political phenomena which are “complex, relatively unstructured and infrequent” lend themselves to be studied less through quantitative than through qualitative approaches ( Bennett & Elman 2007b ). Second, the professionalization of qualitative scholarship triggered a deeper epistemological reflection on its methods. Finally, there is nowadays a shared awareness that complementarities arise from studying the same phenomenon through a variety of approaches employed either jointly or sequentially ( George & Bennett 2005 ).

Civil war is a case in point. The study of civil war has attracted considerable, and increasing, attention on the part of political scientists. In reviewing four books on civil war, Sidney Tarrow remarks how a first wave of quantitative-oriented studies on civil war, starting approximately in the Sixties, has been followed by a second wave of qualitative-oriented studies in the early 2000s ( Tarrow 2007 ). Essential as it was for providing a first understanding of civil war, this first wave of studies suffered from major lacunae pertaining to issues such as over-aggregation of data, problems of unit heterogeneity, and unaccounted regional-level variability (2007: 589). To Tarrow, these gaps are inherent to large-N studies and, as such, cannot be filled by enlarging the data set or by strengthening the quantitative measures; rather they required to (re)turn to case-study research. Similar observations are offered by Nicholas Sambanis ( Sambanis 2004 ). Sambanis was the primary investigator in the Case Study Project on Civil Wars whereby twenty-one case studies on civil war onset and war avoidance are employed to develop and qualify causal inferences drawn from the Collier-Hoeffler and Fearon-Laitin models of civil war. In his view, case studies complement and benefit the formal-quantitative approach because, by expanding theory and making it more fine-grained, eventually improve its accuracy.

Two points can be elicited from the discussion above. First is the acknowledgment that context matters for political phenomena. Pooling events of civil war in a single model does not lead to sufficiently accurate explanations of the phenomenon since it varies across contexts in relevant respects. Second is the confidence that qualitative methods, specifically case-study research, can enhance our understanding of how context matters and what are the relevant respects in which it does so. These suggestions are prima facie hardly disputable. Indeed, case studies are imbued with information that attests to the specificity and variability of social phenomena. However, converting this case-specific information into knowledge of context is not straightforward. In this chapter I refer to this practice as contextualization , and offer an account of how it is pursued, and to what extent, in case-study research. I will do so by drawing a distinction between two techniques of data analysis, process tracing and process embedding , and analyze their interplay in the construction of a case study. Whereas process tracing is amply discussed in methodological debates in political science, process embedding is so far unacknowledged as a self-standing procedure of data analysis.

The chapter is structured as follows. In Section 2 , I examine how the notion of context is understood in political science and the reasons given in support of its relevance for understanding political phenomena. In Section 3 , I discuss contextualization in case-study research by drawing a distinction between process tracing and process embedding. In Section 4 , I illustrate the distinctive role of process embedding vis-à-vis process tracing and will do so by discussing a few case studies on civil war. In Section 5 , I offer some considerations on how far case studies can go in delivering knowledge of context and why, and to what extent, such knowledge should not be forsaken. In section six I conclude.

2. The Relevance of Context in Political Science

In the last decades, several scholars argued that understanding context 1 should be a prominent concern for political scientists. The growing awareness that context influences political phenomena in nontrivial ways prompted the development of measurement procedures, research designs, and theorizations that reflect this influence ( Adcock & Collier 2001 ; Falleti & Lynch 2009 ; Goertz 1994 ; Goodin & Tilly 2006 ; Locke & Thelen 1995 ). In political science, context is understood almost invariably as a causal construct with two distinguishable meanings. A first meaning traces back to John Mackie’s notion of causal field ( Falleti & Lynch 2009 , Goertz 1994 ). In this view, context consists of those background conditions that are necessary for the explanatory variable of interest to produce the effect. Hence, both the context and the explanatory variable qualify as INUS conditions, 2 the distinction between them being mostly pragmatic. Alternatively, context is understood as (a set of) factors influencing the relationship between the explanatory variable and the outcome, and thus the way in which the former affects the latter ( Goertz 1994 ). 3 When political scientists claim that outcomes depend on context, they typically conflate these two meanings.

These two meanings of context survived recent trends in the field. It has been voiced from many quarters that political science is undergoing a mechanistic turn. In the new paradigm, the search for causal mechanisms is a prominent, if not defining, feature of political science inquiry. It is now common knowledge that conceptualizations of mechanism proliferate in the social sciences (Mahoney 2001 , 2007 ; Hedstrom and Ylikoski 2010 ). Mechanisms are sometimes understood in antithesis to universal laws; some other times they are understood as intermediate variables between the cause and the effect; and yet other times they are treated as complex structures responsible for emergent phenomena. Despite the plurality of concepts, the “mechanismic worldview” (Gerring 2008) finds convergence in seeing mechanisms, however understood, as a fundamental part of the causal furniture of the world and of our best scientific explanations. In this view, context is that which enables, impedes, or modifies the mechanism operation, that is, its capacity to bring about the outcome and the way it does so.

Once more, context plays a twofold causal role. On the one hand, it enables the operation of the mechanism, meaning that the mechanism only works when contextual conditions are right. I shall refer to this notion of context-as- interactor . On the other hand, context affects the ways in which the mechanism operates and impacts on the outcome either quantitatively or qualitatively. I shall refer to this notion of context as modifier . In either case, context has deep causal significance and knowledge of it is paramount for fulfilling goals that are valuable for political scientists. In what follows, I briefly present a few scholars who openly argue that contextual knowledge not only improves, but in fact permits, credible explanation of political phenomena, sound policy evaluation, and valid extrapolation. Furthermore, these contributions testify to the three claims made in the previous paragraphs. That is the centrality of mechanisms to political reasoning, the fact that context is mainly understood in causal terms, and the twofold nature it possesses.

Falleti and Lynch (2009) claim that the explanation of political phenomena acquires credibility only if the role of context is accounted for. In their view, explanation in political science consists in the identification of the mechanism responsible for the outcome of interest. However, mechanisms are explanatory only when combined with a characterization of the context in which they operate and an account of the way in which the mechanism and the context interact in bringing the outcome about. The causal effect observed on the outcome of interest depends in fact not only on the mechanism, but on its interaction with the context in which the mechanism is situated. Explanations that disregard the role of context lose credibility not only because they erroneously attribute the outcome uniquely to the mechanism but also because they are liable of faulty generalization. If the outcome depends on the interaction between the mechanism and the context, it follows that when the context changes in relevant respect, the outcome also changes, even if the operating mechanism remains the same. In this view, the mechanism on its own neither fully explains the outcome nor does it enable valid inference about causal impact on the outcome.

Pawson and Tilley defend an approach to policy evaluation grounded on realist principles (Pawson and Tilley 1997 , 2004 ). Realist evaluation is based on program theories, that is theories articulated according to the following conceptual matrix:

(CMO) outcome = mechanism + context

The assumption underlying the matrix is that causal outcomes are engendered by mechanisms acting in context. Policies consist in introducing so-called mechanisms of change into “preexisting social contexts” (1997: 70). The theory on which the program builds formulates hypotheses about how these mechanisms of change overturn, counteract or transform the social processes in place. These social processes result from the interaction between prevailing conditions and currently operating mechanisms which sustained the problem the policy addresses. Mechanisms of change must thus “break into” current social processes and produce the intended change without a major transformation of the prevailing social conditions. It is these conditions that most of the time account for the failure or success of the policy, and their enabling or disabling effect on the mechanism of change must therefore be at the core of evaluation. Accordingly, the task of a realist evaluation is to identify, articulate, test and refine conjectured CMO configurations (1997: 77).

Assessments of external validity are notoriously challenging for the social scientist interested in the extrapolation of scientific findings. This challenge becomes particularly pressing when the scientific finding whose external validity is at stake is a policy claim; that is, a claim about the efficacy of a given intervention. Interventions can be conceived as policy mechanisms, the extrapolation of which raises two main issues concerning matters of context. On the one hand, when the inner working of the policy mechanism is rather well known and possesses some degree of stability, concerns about external validity translate into concerns about their portability ( Falleti & Lynch 2009 ; Woolcock 2013 ). Context matters here because whether the mechanism is portable, that is generalizable to other settings, depends on whether the original and target contexts are “analytically equivalent” ( Falleti & Lynch 2009 : 1160). On the other hand, when policy mechanisms are complex , the policy mechanism does not possess inner stability and decisions about implementation requires the use of discretion on the part of the implementing agent ( Pritchett & Woolcock 2002 : 194). In this case, contextual knowledge is also central but for quite different reasons. Whereas in the former case, it serves to assess whether the original and the target context are equivalent, here it serves to find effective ways to modify and adapt the policy mechanism to the characteristics of the target setting.

3. Contextualization in Case-Study Research

The increasing attention paid by political scientists to causal mechanisms and to the role of context in political phenomena goes a long way in explaining the recent calls for a more extensive and conscious use of case-study research. Two features are invariably regarded as characterizing this research approach: the in-depth character of the investigation and its sensitivity to context ( Crasnow 2019 ; Morgan 2012 ; Yin, 2009 , 2015 ). The former is easily understood within a mechanistic framework. The inquiry into mechanisms requires opening the black box of causation; and case studies offer an avenue for this type of inquiry by digging into the details of a single case while handling a variety of evidential sources ( George & Bennett 2005 ; Gerring 2007 ). As Gerring points out, even if there is no necessary connection between the study of causal mechanisms and case study investigation, “a strong affinity” exists between the two ( Gerring 2008 : 173). Whereas the relationship between case studies and mechanisms has been amply investigated and theorized, context sensitivity, despite broadly consensual, has been mainly taken as self-explanatory.

Roughly speaking, context sensitivity is equated to the permeability of case-study research to particulars of the case ( Crasnow 2019 ). This suggestion might be unproblematic when looking at cases as complex wholes and to case-studying as tying together different bits and pieces of evidence to make sense of that complexity ( Crasnow 2019 ; Morgan 2012 ). In this view, drawing a neat distinction between contextual and case-specific knowledge might be even nonsensical. However, insofar as case studies are taken as informative about causal mechanisms and the context in which they are situated, this is a sensible distinction to make. In other terms, if context is the causal construct understood by political scientists, how does one build knowledge of context from a collection of case-specific information? The discussion below aims at providing a tentative answer to this type of questions. In this chapter, I will confine my analysis to single case studies and thereby exclude small-n, comparative, and cross-case research. Furthermore, I will focus on case studies of an analytic kind that are directed to develop causal explanations of outcomes of interest.

In single case studies directed to provide causal explanations of outcomes of interest, contextualization, that is the conversion of case-specific information into knowledge of context, is achieved by employing jointly two strategies of data analysis, namely process tracing and process embedding . Whereas process tracing is amply discussed in the methodological debate in political science, 4 process embedding is so far unacknowledged as a self-standing procedure of data analysis. Therefore, the characterization below is primarily aimed at defending the relevance of such a distinction. It does so by first disentangling the epistemic goals the two strategies aim to achieve and then highlight three evidentiary principles that govern the application of process embedding.

Process tracing is a strategy of data analysis that:

Addresses first order causal questions: How does the outcome come about?

Epistemic result: Identification of the causal mechanism (M) 5 leading to the outcome of interest (O)

Process embedding is a strategy of data analysis that:

Addresses second order causal questions: Why the mechanism operated as it did in the case at hand?

Epistemic result: Identification of processes 6 in the neighborhood of M (N m ) that causally fit M or its components

Process embedding achieves its epistemic goals with the help of three evidentiary principles. These principles govern contextualization in single case studies and help convert case-specific information into evidence for contextual processes:

  Generality and Sequentiality : Whereas process tracing focuses on the mechanism bringing about the outcome of interest, process embedding targets processes unfolding in the setting in which the mechanism is situated. The first evidentiary principle governing the relationship between process tracing and process embedding distinguishes particular facts pertaining to the mechanism and general facts pertaining to the surrounding processes. The generality principle thus organizes facts according to what is broader in scope, larger in scale, or unfolding within a longer time span. The principle of sequentiality orders pieces of evidence according to what is temporally prior to what. The two principles operate simultaneously, that is pieces of evidence are ordered with respect to each other both according to their temporality and their generality.

  Coherence : 7 Process tracing and process embedding jointly aim at relating the mechanism to its context as a part of the whole. Like inserting a piece in a jigsaw puzzle, also in this case one seeks for coherence between the former and the latter. Coherence between particular facts referring to the mechanism and general facts referring to the context can be searched in a variety of directions. Conditions of coherence have a heuristic function and help drawing the boundaries of N m within which relevant processes can be found. Here are a few such conditions:

Spatial contiguity

Temporal continuity

Systemic relation

Symbolic connection

Network relation

  Causal fitness: The principle of causal fitness here defended resonates with similar notions used to describe certain features of causal relations ( Woodward 2010 ). Broadly speaking, it refers to the “explanatorily adequate” amount of details included in the description of a causal relationship. Translated to the case at hand, we can say that process embedding identifies processes in N m that causally fit M or its components by accounting for M, or M components, specifics. Specifics might pertain to the temporality of the mechanism, such as the specific moment in which the mechanism operates; its spatiality, such as its location or distribution; and more in general, the detail of its instantiation and functioning. In particular, contextual processes explain why the mechanism displays these specific features rather than others, and thus why it triggered in that specific moment rather than earlier or later than that, or why a specific component of the mechanism had that specific value rather than a different one.

The principles highlighted above guide contextualization; however, they are contingent not only on the identification of the main causal mechanism but also on pragmatic features of the study itself. How to delimit the neighborhood of M, and thereby applying the principles of coherence and causal fitness, depends in the first place on the type of mechanism identified and second on what specific features of the mechanism are in need of contextualization as understood above. Ultimately these are issues that depend on the subject matter of interest, the theoretical inclination of the researcher, and the specific debate one is addressing.

In the next section, I will illustrate what type of findings process embedding delivers. I will do so using as examples a few case studies on civil war and disentangling the mechanism identified by way of process tracing from contextual processes identified by process embedding. The point of the discussion is highlighting the explanatory role that the latter plays with respect to the former.

4. Process Embedding in Case Studies on Civil War

The studies discussed in this section all focus on civil war. As mentioned in the introduction, civil war was chosen as it is an area of research which not only has received increasing attention in the last decades but has also experienced a surge in the use of qualitative methods, and case-study research more specifically. The studies below vary along many dimensions among which the extent to which they are theory driven, the research purpose they have, and also the type of mechanism they suggest, be it a chain of events, a set of variables, or a piece of theory. Nevertheless, they all provide a causal explanation of the outcome of interest which can be understood as mechanistic to some extent. They also engage to some extent in process embedding aimed at situating the mechanism at hand in some context regarded as relevant either for pragmatic or theoretical purposes. I use them for illustrative purposes, namely highlighting the explanatory role process embedding plays vis-à-vis process tracing identification of mechanisms. Meanwhile, I identify the relevant contextual conditions, which will ground the discussion in section five .

4.1. Historically Constructed Political Identity as Context for Inter-State Conflicts in Former Yugoslavia

Gagnon (1994) studies the inter-state conflicts sparked in former Yugoslavia in the early Nineties. Against conventional wisdom, Gagnon argues that violent conflicts fought along ethnic lines are caused by within-group, rather than external, dynamics. He claims that “the external conflict, although justified and described in terms of relations with other ethnic groups … has its main goal within the state, among members of the same ethnicity” (1994: 131). According to the mechanism described by Gagnon, ruling elites resort to conflictual policies when domestic threats arise; namely, challenger elites seek to mobilize the population majority in a way that threatens the economic or political structure on which the rulers’ power is based (1994: 135). When rules of the game forbid the use of force against political opponents, ruling elites whose power basis is at risk typically respond by shifting the focus of the political debate away from issues where they feel most threatened. Specifically, they define collective interest in other terms and create an image of threat to that very interest.

How collective interest is constructed by ruling elites, says Gagnon, depends on the context. In Serbia, collective political interest was defined as the survival of the Serbian people and the image of an external threat as directed to that interest because historical processes made Serbian identity politically salient. Since the struggle against the Ottoman Turks, the Serbian national myth played a central role first in the expansion of the Serbian state in the nineteenth and early twentieth century, then in Yugoslav politics until 1941, and then during the second world war (1994: 141). Furthermore, in the Yugoslav republics ethnic identity used to determine the distribution of certain positions according to the size of each ethnic group. These processes among others constituted what Gagnon defines as the “historical construction of political identity in terms of ethnics identity” (1994: 141).

Processes pertaining to the historical construction of political identity explain why Serbian ruling elites leveraged a specifically ethnic identity when shielding off domestic threats emanating from challengers to the economic and political status quo. The national-ethnic identity was salient, and thus exploitable by ruling elites, because it had acquired political force throughout historical processes that maintained that identity alive and politically significant. Thus, it became the identity around which to organize the collective interest and construct the image of an external, rather than domestic, threat. Eventually, it informed the cleavage along which the subsequent war was to be fought.

4.2. Sectarian Political System as Context for the Civil War in Lebanon

Makdisi and Sadaka (2005) study the civil war which broke out in Lebanon in 1975 and ended in 1990 shortly after an accord of national reconciliation was signed in Taif, Saudi Arabia. Both internal and external factors are responsible for the chain of events leading to the war outbreak and its duration. Among the former, Makdisi and Sadaka include religious fractionalization in the country (2005: 59). Three main religious communities coexist in the Lebanese society, Christian Maronites, Muslim Sunnis, and the Muslim Shi’a together with a plurality of minor groups. Religious militias coalesced around two main warring camps and were joined by other Lebanese secular groups and foreign parties. Even though very heterogeneous in terms of groups involved, the opposition between the two camps was broadly drawn along confessional lines featuring Christian Maronites on the one side and Muslim (Shi’a and Sunni) on the other.

Makdisi and Sadaka show how the confessional dimension of the war found its roots in the sectarian political system in place in Lebanon since 1943. The constitution contemplated that religious communities had to be equitably represented in public employment and cabinet posts (2005: 61). The system thus organized the distribution of power according to a sophisticated schema of sectarian rules. It assigned the main political positions in the country to the three leading communities namely, a Maronite Christian was given the role of president of the republic, a Shiite Muslim the role of speaker of the house, and a Sunni Muslim the premiership. Cabinet posts were apportioned among the six main religious communities and similar arrangements were adopted for the allocation of parliamentary seats and many positions in the public administration. Even though the Maronite community was overall favored given the strong executive power held by the president, the arrangements were conceived and implemented in a way that preserved the balance among communities and prevented any single political, religious, or politicoreligious groups from raising to hegemony (2005: 62).

The sectarian political system explains why religious fragmentation could play such an important role in the Lebanese civil war. The system regulated the distribution of political power directly, and economic power indirectly through the assignment of positions in the public administration. When tensions and dissatisfaction started mounting among various communities in the years before the war due to the worsening of their relative economic conditions, these were voiced by political leaders as calls for a change in the sectarian system. Muslim and secular parties found common grounds in fighting against the status quo represented by the political system in its current shape on the presumption that changes in the system sectarian formula would have led them to acquire major economic opportunities. For these reasons, Makdisi and Sadaka suggest that the underlying political system enabled religious fragmentation to acquire causal prominence in the events leading to war.

4.3. Power Vacuum in Northern Iraq as Context for Escalating Political Violence between PKK and the Turkish State

Sezgin (2013) studies the escalation of ongoing political violence in the conflict between the Kurdistan Workers’ Party (PKK) and the Turkish state in the period between 1992 and 1995. The conflict started approximately in 1984 causing significant losses in both human and economic terms; however, the intensity of violence increased radically after 1992. Sezgin traces the mechanism leading to such escalation back to Turkey’s foreign policy: by changing the transnational landscape in which PKK operated, this policy brought about the emergence of “opportune moments” for PKK—moments in which the perceived likelihood of success is enhanced (2013: 173)—leading in turn to a radical escalation of violence. Between 1991 and 1992, in fact, Turkey started intense military incursions in northern Iraq to destroy PKK sanctuaries. Turkish massive air attacks, however, caused casualties in Iraqi Kurdish villages alienating the civilian population and fostering the alliance between Iraqi Kurds, their leaders, and PKK. Ultimately, this strengthened PKK resistance which started fighting the Turkish military on the open battlefield (2013: 182).

Sezgin shows how the transnational landscape in which PKK operated was shaped by processes unfolding at that time in neighboring Iraq. Iraq was involved in the Persian Gulf War after the invasion of Kuwait in 1990. Severely defeated in the Gulf War, the Iraqi regime had to deal with the concurrent Kurdish uprising in the north of the country. The repression perpetrated against Kurd insurgents by Iraqi forces and the ensuing massive number of refugees led to the adoption of a United Nations resolution that established a No-Fly Zone and Safe Heaven for Kurds in northern Iraq. By preventing Iraqi forces from entering the area, these processes generated a power vacuum in the Kurdish Inhabited Area (KIA) in Northern Iraq; that is a situation in which no provincial or regional political authority had effective control.

The PKK found a new harbor in this situation from which it could have access not only to humanitarian supply but also to recruitment potential among Iraqi Kurds. The processes leading to the creation of a power vacuum in KIA thus shaped the environment in which PKK was operating. In the absence of political control, PKK was free to enshrine in the area, reap its resources, and move freely across the border. The conditions characterizing such power vacuum explain why the transnational landscape in which PKK was operating at that time changed as it did, namely it featured an emergent collaboration between the PKK and Iraqi Kurds when the Turkish state intensified its attacks against PKK sanctuaries in Northern Iraq. This fostered alliance provided PKK with the opportunity to respond to Turkish attacks with stronger resistance thereby engaging in fighting on the open battlefield.

5. Process Embedding: What Is It Good For?

The discussion of the cases above suggests three considerations. The first regards the role that process embedding plays vis-à-vis process tracing in a single case study. The second concerns the role that the contextual knowledge delivered by process embedding plays vis-à-vis the conceptualization of context as discussed in section two . The third regards the relevance of contextualization in case studies for the broader aims of scientific practice, and in particular policy-making. I will address these issues in turn.

In single case studies that identify causal mechanisms for outcomes of interest, process embedding offers explanations of why the mechanism operated as it did in the case at hand. These explanations refer to processes unfolding in its neighborhood that account for the way in which the mechanism is concretely instantiated. In other terms, they respond to contrastive questions about the case-specific details of the mechanism. As an example, consider the case of inter-state war in former Yugoslavia discussed above. The mechanism explaining the inter-state ethnic war can be succinctly summarized as follows:

Domestic challengers threaten ruling elites’ basis of economic and political power.

Elites shift the focus of debate away by constructing collective interest in other terms.

Elites create an image of threat to collective interest as defined in (b).

Elites resort to conflictual policies to defend collective interest.

In this case, process embedding responds to the question: Why Serbian ruling elites constructed collective interest in ethnic—rather than religious, class, or political—terms? Similarly, in the case of the Lebanese civil war, contextual processes explain why religious, rather than ethnic, fragmentation was causally relevant to the war. In the case of conflict between PKK and the Turkish state instead, the relevant question is why the transnational landscape in which PKK operated featured an alliance with Iraqi Kurds rather than Syrian or Iranian Kurds. The relevant contrast class to which the questions above refer is not necessarily fully spelled out and it either emerges from the case itself or is part of background knowledge.

Incidentally, two things can be noted. Process embedding addresses contrastive questions concerning parts of the mechanism, rather than the whole of it. These could be the components responsible for triggering the causal chain, jointly or alone, or could be some intermediate components. Furthermore, it is now clear how process tracing and process embedding differ. Whereas the former accounts for the causal arrangement of the parts in the mechanisms, explaining how they are causally connected, the latter accounts for their specific instantiation, explaining why a given component instantiated as it did rather than in a different way. These remarks make patent the subordinate position of process embedding in case study research. It not only depends on process tracing identification of the causal mechanism, but is also secondary to it; meaning by this that the causal explanation of the outcome of interest stands or falls independently of the contribution provided by process embedding. This fact can partially explain why the degree of contextualization is so various across case studies and most often incomplete.

The second reflection concerns what it means saying that in case-study research process embedding identifies the context for phenomena of interest. In section two , we pointed out an inherent ambiguity in the notion of context as it is used in political science. Context sometimes refers to conditions that enable or prevent the mechanism from functioning; in other terms, these are factors necessary under the circumstances for the mechanism to bring about the outcome of interest. In this case, we defined context-as- interactor . Some other times instead, context refers to conditions that modify the mechanism operation. That is, the context affects the mechanism functioning and the ensuing outcome either quantitatively or qualitatively. In this case, context is defined as a modifier . The question thus is: what does it mean to say that the historical construction of political identity is context for the inter-state war in former Yugoslavia; that the sectarian political system is context for the Lebanese civil war; or that the power vacuum in Northern Iraq is context for the escalation of violence between PKK and the Turkish state?

Single case studies retain the same ambiguity in the meaning of context highlighted above. Provided that claims of necessity are beyond the reach of a single case study, it is fair to acknowledge that contextual evidence and background knowledge jointly suggest an interpretation in either sense. Sometimes contextual processes seem necessary under the circumstances for the mechanism operation; some other time, they simply seem to act as modifier. In the case discussed by Sezgin, the power vacuum in Northern Iraq enabled the escalation of violence following Turkish military incursions against PKK in that area. In the absence of that power vacuum, in fact, PKK could not have rooted so firmly in the region, have access to military and human resources there, and find the support it eventually needed to fight back the Turkish army with increasing violence. In the case discussed by Gagnon, instead, the evidence suggests that the historical construction of political identity in ethnic terms affected qualitatively the operation of the mechanism and the ensuing outcome. That is, it affected the way in which the interest of Serbian people was constructed and the ethnic cleavage along which the war was eventually fought. However, nothing suggests that a different way of constructing that interest would not have been found by ruling elites eager to defend the basis of their power from domestic threats.

The preceding discussion suggests that contextual conditions in single case studies explain why the mechanism operated in a specific way in the case at hand and do so either as interactor or as modifier for the mechanism itself. Thus, in both cases they are second order causes, meaning that contextual conditions in single case studies do not act upon the outcome directly; their action in this respect is indirect and is filtered by the mechanism. What good does come from such knowledge? Specifically, what good does come from it when the purpose is ultimately practice-oriented and directed to the extrapolation of causal claims, that is the assessment of external validity, or intervention in target settings? The question is neither redundant nor obvious. The reason is that typically first order causes are regarded as prominent for these purposes, that is causes that have a direct effect on the outcome of interest in conjunction with the main explanatory variable. Once their presence is ascertained in the target settings, considerations about second order causes of a processual nature seem to complicate the matter in unnecessary ways.

The distinction between context-as-interactor and context as modifier is relevant here. Let us first consider the case of contextual conditions as interactor for the mechanism. In this case, the evidence suggests that contextual conditions enable or prevent the mechanism from functioning, and their presence or absence in the target setting is therefore decisive for the intended goal. In this respect, they must be regarded on par with first order causes, which are necessary under the circumstances for producing the outcome of interest. Things are different when it comes to the context as modifier. In this scenario, case-specific evidence and background knowledge give us reason to believe that the mechanism would work anyway even though differently than it would in the present conditions. Whether the quantitative or qualitative difference one would eventually observe on the outcome is relevant depends ultimately on the case at hand. In this sense, context as modifier seem not to matter in a fundamental way, even if it can be helpful for instance for predictive purposes. We know for instance that if in a region where conditions for civil wars are present there is a historical insistence on ethnic identity as a politically relevant factor, the civil war could easily take an ethnic bent.

However, things look a bit different when we start thinking of those contextual conditions in terms of sociohistorical processes as those brought to light in the cases discussed in this chapter. Even if we cannot generalize from this point, it is plausible that many mechanisms of interest to political scientists find roots in this type of processes. Thinking of contextual conditions in terms of processes shifts in an important way the perspective on questions of external validity and intervention in target settings. We often think of these tasks as a matter of setting the conditions right or fixing the background conditions to achieve the intended outcome. However, if contextual conditions are sociohistorical processes, intervention and extrapolation then rather consist in disembedding and reembedding policy mechanisms. In this view, an intervention modifies or replaces existing mechanisms, and consequently implies the alteration or disruption of the processes related to it; processes which extend in time and space and interact in multiple ways. Disembedding has thus far-reaching consequences beyond the outcome, and the case, of interest. In a similar vein, reembedding implies not only the disruption of existing processes but also the search for causal fit between them and the new mechanism.

6. Conclusion

In this chapter, I discuss contextualization in case-study research, and illustrate the output of this process by looking at studies on civil wars. Recently, political science has been invested by a return to the use of qualitative methods and, specifically, case studies. I suggest that the renaissance of the qualitative might be due to the increasing attention of political scientists to causal mechanisms and to the context in which they are situated. Well-known features of case-study research such as its in-depth character and context sensitivity might then explain why it is regarded as a fruitful strategy of inquiry into political phenomena. However, whereas there is much debate on how case studies can help identify causal mechanisms, how case-specific information is converted into knowledge of context is an issue so far left unattended.

I argue that contextualization in case-study research, that is the conversion of case-specific information into knowledge of context, is pursued by the joint use of process tracing and process embedding. Process tracing is a well-known strategy of causal inference that is directed to the identification of causal mechanisms. Process embedding is instead directed to identify processes unfolding in the mechanism neighborhood that causally fit the mechanism or its components. Whereas process tracing explains how the outcome of interest is brought about, process embedding is directed to explain why the mechanism operated as it did under the circumstances. It thus addresses contrastive questions regarding the mechanism specifics. To this end, its application is governed by three main evidentiary principles, namely generality, coherence, and fitness.

Even though contextualization is pursued through the joint application of process tracing and process embedding, the latter presupposes the former while the opposite is not the case. Process embedding has thus an ancillary role in the explanation of political phenomena as testified by the intermittent and incomplete degree of contextualization, as understood here, in case-study research. Nevertheless, contextualization is consequential when the inquiry is practice-oriented. Case studies suggest that contextual factors are causes of the second order with respect to the outcome of interest either as interactor or as modifier for the mechanism at hand. In the former case they are on par with first order causes that are jointly necessary for the mechanism to bring the outcome about. In the latter case, their role is less prominent but might be equally important since it points out how a given mechanism might operate in the setting of interest and, in turn, affect the outcome either qualitatively or quantitatively.

Lastly, understanding the context in terms of sociohistorical processes rather than background conditions might shift the way we problematize the practice of extrapolation and intervention in the social sciences. When treating the context as the set of background conditions that must be in place for the mechanism to operate and the intended outcome to obtain, the paramount concern is checking whether conditions are right in the target setting. At the level of intervention, this view legitimizes actions directed to rectify or fix the background conditions in the target setting in such a way as to enable the smooth unimpeded operation of the mechanism there. However, when background conditions are in fact processes of the kind described in this paper, they cannot be easily turned into the target of actions directed to their rectification. Thus, thinking of extrapolation and intervention as directed to disembed and reembed policy mechanism demands a very attentive and careful look at the context and the processes that constitute it. There are empirical, practical, and ethical reasons for recommending this sensitivity to context, which however deserve separate scrutiny and further inquiry.

The context refers here uniquely to the subject of inquiry. It ignores the context of inquiry which is relevant for the research purpose, the research question, the background beliefs and presuppositions, and so on. For these considerations see Goodin & Tilly (2006) .

An INUS condition is a nonredundant insufficient component of an unnecessary sufficient set for the outcome (see Mackie 1965 , 1974 ).

In quantitative research, these two meanings are distinct by referring to interaction terms in the former case and moderators in the latter.

For a discussion of process tracing in political science and social science more in general see Beach & Pedersen 2019 ; Bennett & George 1997 ; Collier 2011 ; Crasnow 2017 ; George & Bennett 2005 ; Little 1991 , 1998 ; Mahoney 2015 ; Steel 2004 , 2008 ; Waldner 2015 .

In what follows, my understanding of mechanism is very liberal and includes chains of events, complex structures, their abstract description, and so on. Process-embedding is described here in broad strokes and equally applies to any conceptualization of mechanism.

As I intend it here, process is a generic for mechanism. This terminological choice is mostly dictated by clarity purposes (distinguishing the main mechanism, which explains the outcome of interest, from those which are somehow ancillary to it).

Case Study | Definition, Examples & Methods

Published on 5 May 2022 by Shona McCombes . Revised on 30 January 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating, and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyse the case.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Prevent plagiarism, run a free check.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

If you find yourself aiming to simultaneously investigate and solve an issue, consider conducting action research . As its name suggests, action research conducts research and takes action at the same time, and is highly iterative and flexible. 

However, you can also choose a more common or representative case to exemplify a particular category, experience, or phenomenon.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data .

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methods , results , and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyse its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

 Famous Case Studies

• Anna O – One of the most famous case studies, documenting psychoanalyst Josef Breuer’s treatment of “Anna O” (real name Bertha Pappenheim) for hysteria in the late 1800s using early psychoanalytic theory.
• Little Hans – A child psychoanalysis case study published by Sigmund Freud in 1909 analyzing his five-year-old patient Herbert Graf’s house phobia as related to the Oedipus complex.
• Bruce/Brenda – Gender identity case of the boy (Bruce) whose botched circumcision led psychologist John Money to advise gender reassignment and raise him as a girl (Brenda) in the 1960s.
• Genie Wiley – Linguistics/psychological development case of the victim of extreme isolation abuse who was studied in 1970s California for effects of early language deprivation on acquiring speech later in life.
• Phineas Gage – One of the most famous neuropsychology case studies analyzes personality changes in railroad worker Phineas Gage after an 1848 brain injury involving a tamping iron piercing his skull.

Clinical Case Studies

• Studying the effectiveness of psychotherapy approaches with an individual patient
• Assessing and treating mental illnesses like depression, anxiety disorders, PTSD
• Neuropsychological cases investigating brain injuries or disorders

Child Psychology Case Studies

• Studying psychological development from birth through adolescence
• Cases of learning disabilities, autism spectrum disorders, ADHD
• Effects of trauma, abuse, deprivation on development

Types of Case Studies

• Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
• Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
• Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
• Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
• Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
• Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

• Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
• Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
• Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

• News/Media – News coverage of events related to the case study.
• Academic articles – Journal articles, dissertations etc. that discuss the case.
• Government reports – Official data and records related to the case context.
• Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

• Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
• Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
• School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

• Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
• Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

• Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
• Include client demographics like age and gender, information about social relationships, and mental health history.
• Describe all physical, emotional, and/or sensory symptoms reported by the client.
• Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
• Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
• Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

• Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
• Present the results of the intervention,including any quantitative or qualitative data collected.
• For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

• Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
• Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
• Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
• Offer clinical implications, and suggest future research directions.

5. Additional Items

• Thank specific assistants for writing support only. No patient acknowledgments.
• References should directly support any key claims or quotes included.
• Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feelings may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

Case Study – Methods, Examples and Guide

Table of Contents

A case study is a research method that involves an in-depth examination and analysis of a particular phenomenon or case, such as an individual, organization, community, event, or situation.

It is a qualitative research approach that aims to provide a detailed and comprehensive understanding of the case being studied. Case studies typically involve multiple sources of data, including interviews, observations, documents, and artifacts, which are analyzed using various techniques, such as content analysis, thematic analysis, and grounded theory. The findings of a case study are often used to develop theories, inform policy or practice, or generate new research questions.

Types of Case Study

Types and Methods of Case Study are as follows:

Single-Case Study

A single-case study is an in-depth analysis of a single case. This type of case study is useful when the researcher wants to understand a specific phenomenon in detail.

For Example , A researcher might conduct a single-case study on a particular individual to understand their experiences with a particular health condition or a specific organization to explore their management practices. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a single-case study are often used to generate new research questions, develop theories, or inform policy or practice.

Multiple-Case Study

A multiple-case study involves the analysis of several cases that are similar in nature. This type of case study is useful when the researcher wants to identify similarities and differences between the cases.

For Example, a researcher might conduct a multiple-case study on several companies to explore the factors that contribute to their success or failure. The researcher collects data from each case, compares and contrasts the findings, and uses various techniques to analyze the data, such as comparative analysis or pattern-matching. The findings of a multiple-case study can be used to develop theories, inform policy or practice, or generate new research questions.

Exploratory Case Study

An exploratory case study is used to explore a new or understudied phenomenon. This type of case study is useful when the researcher wants to generate hypotheses or theories about the phenomenon.

For Example, a researcher might conduct an exploratory case study on a new technology to understand its potential impact on society. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as grounded theory or content analysis. The findings of an exploratory case study can be used to generate new research questions, develop theories, or inform policy or practice.

Descriptive Case Study

A descriptive case study is used to describe a particular phenomenon in detail. This type of case study is useful when the researcher wants to provide a comprehensive account of the phenomenon.

For Example, a researcher might conduct a descriptive case study on a particular community to understand its social and economic characteristics. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a descriptive case study can be used to inform policy or practice or generate new research questions.

Instrumental Case Study

An instrumental case study is used to understand a particular phenomenon that is instrumental in achieving a particular goal. This type of case study is useful when the researcher wants to understand the role of the phenomenon in achieving the goal.

For Example, a researcher might conduct an instrumental case study on a particular policy to understand its impact on achieving a particular goal, such as reducing poverty. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of an instrumental case study can be used to inform policy or practice or generate new research questions.

Case Study Data Collection Methods

Here are some common data collection methods for case studies:

Interviews involve asking questions to individuals who have knowledge or experience relevant to the case study. Interviews can be structured (where the same questions are asked to all participants) or unstructured (where the interviewer follows up on the responses with further questions). Interviews can be conducted in person, over the phone, or through video conferencing.

Observations

Observations involve watching and recording the behavior and activities of individuals or groups relevant to the case study. Observations can be participant (where the researcher actively participates in the activities) or non-participant (where the researcher observes from a distance). Observations can be recorded using notes, audio or video recordings, or photographs.

Documents can be used as a source of information for case studies. Documents can include reports, memos, emails, letters, and other written materials related to the case study. Documents can be collected from the case study participants or from public sources.

Surveys involve asking a set of questions to a sample of individuals relevant to the case study. Surveys can be administered in person, over the phone, through mail or email, or online. Surveys can be used to gather information on attitudes, opinions, or behaviors related to the case study.

Artifacts are physical objects relevant to the case study. Artifacts can include tools, equipment, products, or other objects that provide insights into the case study phenomenon.

How to conduct Case Study Research

Conducting a case study research involves several steps that need to be followed to ensure the quality and rigor of the study. Here are the steps to conduct case study research:

• Define the research questions: The first step in conducting a case study research is to define the research questions. The research questions should be specific, measurable, and relevant to the case study phenomenon under investigation.
• Select the case: The next step is to select the case or cases to be studied. The case should be relevant to the research questions and should provide rich and diverse data that can be used to answer the research questions.
• Collect data: Data can be collected using various methods, such as interviews, observations, documents, surveys, and artifacts. The data collection method should be selected based on the research questions and the nature of the case study phenomenon.
• Analyze the data: The data collected from the case study should be analyzed using various techniques, such as content analysis, thematic analysis, or grounded theory. The analysis should be guided by the research questions and should aim to provide insights and conclusions relevant to the research questions.
• Draw conclusions: The conclusions drawn from the case study should be based on the data analysis and should be relevant to the research questions. The conclusions should be supported by evidence and should be clearly stated.
• Validate the findings: The findings of the case study should be validated by reviewing the data and the analysis with participants or other experts in the field. This helps to ensure the validity and reliability of the findings.
• Write the report: The final step is to write the report of the case study research. The report should provide a clear description of the case study phenomenon, the research questions, the data collection methods, the data analysis, the findings, and the conclusions. The report should be written in a clear and concise manner and should follow the guidelines for academic writing.

Examples of Case Study

Here are some examples of case study research:

• The Hawthorne Studies : Conducted between 1924 and 1932, the Hawthorne Studies were a series of case studies conducted by Elton Mayo and his colleagues to examine the impact of work environment on employee productivity. The studies were conducted at the Hawthorne Works plant of the Western Electric Company in Chicago and included interviews, observations, and experiments.
• The Stanford Prison Experiment: Conducted in 1971, the Stanford Prison Experiment was a case study conducted by Philip Zimbardo to examine the psychological effects of power and authority. The study involved simulating a prison environment and assigning participants to the role of guards or prisoners. The study was controversial due to the ethical issues it raised.
• The Challenger Disaster: The Challenger Disaster was a case study conducted to examine the causes of the Space Shuttle Challenger explosion in 1986. The study included interviews, observations, and analysis of data to identify the technical, organizational, and cultural factors that contributed to the disaster.
• The Enron Scandal: The Enron Scandal was a case study conducted to examine the causes of the Enron Corporation’s bankruptcy in 2001. The study included interviews, analysis of financial data, and review of documents to identify the accounting practices, corporate culture, and ethical issues that led to the company’s downfall.
• The Fukushima Nuclear Disaster : The Fukushima Nuclear Disaster was a case study conducted to examine the causes of the nuclear accident that occurred at the Fukushima Daiichi Nuclear Power Plant in Japan in 2011. The study included interviews, analysis of data, and review of documents to identify the technical, organizational, and cultural factors that contributed to the disaster.

Application of Case Study

What Is a Case Study and Why You Should Use Them

Case studies can provide more insights into your business while helping you conduct further research with robust qualitative data analysis to learn more.

If you're in charge of running a company, then you're likely always looking for new ways to run your business more efficiently and increase your customer base while streamlining as many processes as possible.

Unfortunately, it can sometimes be difficult to determine how to go about implementing the proper program in order to be successful. This is why many business owners opt to conduct a case study, which can help significantly. Whether you've been struggling with brand consistency or some other problem, the right case study can identify why your problem exists as well as provide a way to rectify it.

A case study is a great tool that many businesses aren't even aware exists, and there are marketing experts like Mailchimp who can provide you with step-by-step assistance with implementing a plan with a case study. Many companies discover that not only do they need to start a blog in order to improve business, but they also need to create specific and relevant blog titles.

If your company already has a blog, then optimizing your blog posts may be helpful. Regardless of the obstacles that are preventing you from achieving all your professional goals, a case study can work wonders in helping you reverse this issue.

What is a case study?

A case study is a comprehensive report of the results of theory testing or examining emerging themes of a business in real life context. Case studies are also often used in the healthcare industry, conducting health services research with primary research interest around routinely collected healthcare data.

However, for businesses, the purpose of a case study is to help small business owners or company leaders identify the issues and conduct further research into what may be preventing success through information collection, client or customer interviews, and in-depth data analysis.

Knowing the case study definition is crucial for any business owner. By identifying the issues that are hindering a company from achieving all its goals, it's easier to make the necessary corrections to promote success through influenced data collection.

Why are case studies important?

Now that we've answered the questions, "what is a case study?" Why are case studies important? Some of the top reasons why case studies are important include:

• Understand complex issues: Even after you conduct a significant amount of market research , you might have a difficult time understanding exactly what it means. While you might have the basics down, conducting a case study can help you see how that information is applied. Then, when you see how the information can make a difference in business decisions, it could make it easier to understand complex issues.
• Collect data: A case study can also help with data tracking . A case study is a data collection method that can help you describe the information that you have available to you. Then, you can present that information in a way the reader can understand.
• Conduct evaluations: As you learn more about how to write a case study, remember that you can also use a case study to conduct evaluations of a specific situation. A case study is a great way to learn more about complex situations, and you can evaluate how various people responded in that situation. By conducting a case study evaluation, you can learn more about what has worked well, what has not, and what you might want to change in the future.
• Identify potential solutions: A case study can also help you identify solutions to potential problems. If you have an issue in your business that you are trying to solve, you may be able to take a look at a case study where someone has dealt with a similar situation in the past. For example, you may uncover data bias in a specific solution that you would like to address when you tackle the issue on your own. If you need help solving a difficult problem, a case study may be able to help you.

Remember that you can also use case studies to target your audience . If you want to show your audience that you have a significant level of expertise in a field, you may want to publish some case studies that you have handled in the past. Then, when your audience sees that you have had success in a specific area, they may be more likely to provide you with their business. In essence, case studies can be looked at as the original method of social proof, showcasing exactly how you can help someone solve their problems.

What are the benefits of writing a business case study?

Although writing a case study can seem like a tedious task, there are many benefits to conducting one through an in depth qualitative research process.

• Industry understanding: First of all, a case study can give you an in-depth understanding of your industry through a particular conceptual framework and help you identify hidden problems that are preventing you from transcending into the business world.
• Develop theories: If you decide to write a business case study, it provides you with an opportunity to develop new theories. You might have a theory about how to solve a specific problem, but you need to write a business case study to see exactly how that theory has unfolded in the past. Then, you can figure out if you want to apply your theory to a similar issue in the future.
• Evaluate interventions: When you write a business case study that focuses on a specific situation you have been through in the past, you can uncover whether that intervention was truly helpful. This can make it easier to figure out whether you want to use the same intervention in a similar situation in the future.
• Identify best practices: If you want to stay on top of the best practices in your field, conducting case studies can help by allowing you to identify patterns and trends and develop a new list of best practices that you can follow in the future.
• Versatility: Writing a case study also provides you with more versatility. If you want to expand your business applications, you need to figure out how you respond to various problems. When you run a business case study, you open the door to new opportunities, new applications, and new techniques that could help you make a difference in your business down the road.
• Solve problems: Writing a great case study can dramatically improve your chances of reversing your problem and improving your business.
• These are just a few of the biggest benefits you might experience if you decide to publish your case studies. They can be an effective tool for learning, showcasing your talents, and teaching some of your other employees. If you want to grow your audience , you may want to consider publishing some case studies.

What are the limitations of case studies?

Case studies can be a wonderful tool for any business of any size to use to gain an in-depth understanding of their clients, products, customers, or services, but there are limitations.

One limitation of case studies is the fact that, unless there are other recently published examples, there is nothing to compare them to since, most of the time, you are conducting a single, not multiple, case studies.

Another limitation is the fact that most case studies can lack scientific evidence.

Types of case studies

There are specific types of case studies to choose from, and each specific type will yield different results. Some case study types even overlap, which is sometimes more favorable, as they provide even more pertinent data.

Here are overviews of the different types of case studies, each with its own theoretical framework, so you can determine which type would be most effective for helping you meet your goals.

Explanatory case studies

Explanatory case studies are pretty straightforward, as they're not difficult to interpret. This type of case study is best if there aren't many variables involved because explanatory case studies can easily answer questions like "how" and "why" through theory development.

Exploratory case studies

An exploratory case study does exactly what its name implies: it goes into specific detail about the topic at hand in a natural, real-life context with qualitative research.

The benefits of exploratory case studies are limitless, with the main one being that it offers a great deal of flexibility. Having flexibility when writing a case study is important because you can't always predict what obstacles might arise during the qualitative research process.

Collective case studies

Collective case studies require you to study many different individuals in order to obtain usable data.

Case studies that involve an investigation of people will involve many different variables, all of which can't be predicted. Despite this fact, there are many benefits of collective case studies, including the fact that it allows an ongoing analysis of the data collected.

Intrinsic case studies

This type of study differs from the others as it focuses on the inquiry of one specific instance among many possibilities.

Many people prefer these types of case studies because it allows them to learn about the particular instance that they wish to investigate further.

Instrumental case studies

An instrumental case study is similar to an intrinsic one, as it focuses on a particular instance, whether it's a person, organization, or something different.

One thing that differentiates instrumental case studies from intrinsic ones is the fact that instrumental case studies aren't chosen merely because a person is interested in learning about a specific instance.

Tips for writing a case study

If you have decided to write case studies for your company, then you may be unsure of where to start or which type to conduct.

However, it doesn't have to be difficult or confusing to begin conducting a case study that will help you identify ways to improve your business.

Here are some helpful tips for writing your case studies:

1. Your case study must be written in the proper format

When writing a case study, the format that you should be similar to this:

Administrative summary

The executive summary is an overview of what your report will contain, written in a concise manner while providing real-life context.

Despite the fact that the executive summary should appear at the beginning of your case studies, it shouldn't be written until you've completed the entire report because if you write it before you finish the report, this summary may not be completely accurate.

Key problem statement

In this section of your case study, you will briefly describe the problem that you hope to solve by conducting the study. You will have the opportunity to elaborate on the problem that you're focusing on as you get into the breadth of the report.

Problem exploration

This part of the case study isn't as brief as the other two, and it goes into more detail about the problem at hand. Your problem exploration must include why the identified problem needs to be solved as well as the urgency of solving it.

Additionally, it must include justification for conducting the problem-solving, as the benefits must outweigh the efforts and costs.

Proposed resolution

This case study section will also be lengthier than the first two. It must include how you propose going about rectifying the problem. The "recommended solution" section must also include potential obstacles that you might experience, as well as how these will be managed.

Furthermore, you will need to list alternative solutions and explain the reason the chosen solution is best. Charts can enhance your report and make it easier to read, and provide as much proof to substantiate your claim as possible.

Overview of monetary consideration

An overview of monetary consideration is essential for all case studies, as it will be used to convince all involved parties why your project should be funded. You must successfully convince them that the cost is worth the investment it will require. It's important that you stress the necessity for this particular case study and explain the expected outcome.

Execution timeline

In the execution times of case studies, you explain how long you predict it will take to implement your study. The shorter the time it will take to implement your plan, the more apt it is to be approved. However, be sure to provide a reasonable timeline, taking into consideration any additional time that might be needed due to obstacles.

Always include a conclusion in your case study. This is where you will briefly wrap up your entire proposal, stressing the benefits of completing the data collection and data analysis in order to rectify your problem.

2. Make it clear and comprehensive

You want to write your case studies with as much clarity as possible so that every aspect of the report is understood. Be sure to double-check your grammar, spelling, punctuation, and more, as you don't want to submit a poorly-written document.

Not only would a poorly-written case study fail to prove that what you are trying to achieve is important, but it would also increase the chances that your report will be tossed aside and not taken seriously.

3. Don't rush through the process

Writing the perfect case study takes time and patience. Rushing could result in your forgetting to include information that is crucial to your entire study. Don't waste your time creating a study that simply isn't ready. Take the necessary time to perform all the research necessary to write the best case study possible.

Depending on the case study, conducting case study research could mean using qualitative methods, quantitative methods, or both. Qualitative research questions focus on non-numerical data, such as how people feel, their beliefs, their experiences, and so on.

Meanwhile, quantitative research questions focus on numerical or statistical data collection to explain causal links or get an in-depth picture.

It is also important to collect insightful and constructive feedback. This will help you better understand the outcome as well as any changes you need to make to future case studies. Consider using formal and informal ways to collect feedback to ensure that you get a range of opinions and perspectives.

4. Be confident in your theory development

While writing your case study or conducting your formal experimental investigation, you should have confidence in yourself and what you're proposing in your report. If you took the time to gather all the pertinent data collected to complete the report, don't second-guess yourself or doubt your abilities. If you believe your report will be amazing, then it likely will be.

5. Case studies and all qualitative research are long

It's expected that multiple case studies are going to be incredibly boring, and there is no way around this. However, it doesn't mean you can choose your language carefully in order to keep your audience as engaged as possible.

If your audience loses interest in your case study at the beginning, for whatever reason, then this increases the likelihood that your case study will not be funded.

Case study examples

If you want to learn more about how to write a case study, it might be beneficial to take a look at a few case study examples. Below are a few interesting case study examples you may want to take a closer look at.

• Phineas Gage by John Martin Marlow : One of the most famous case studies comes from the medical field, and it is about the story of Phineas Gage, a man who had a railroad spike driven through his head in 1848. As he was working on a railroad, an explosive charge went off prematurely, sending a railroad rod through his head. Even though he survived this incident, he lost his left eye. However, Phineas Gage was studied extensively over the years because his experiences had a significant, lasting impact on his personality. This served as a case study because his injury showed different parts of the brain have different functions.
• Kitty Genovese and the bystander effect : This is a tragic case study that discusses the murder of Kitty Genovese, a woman attacked and murdered in Queens, New York City. Shockingly, while numerous neighbors watched the scene, nobody called for help because they assumed someone else would. This case study helped to define the bystander effect, which is when a person fails to intervene during an emergency because other people are around.
• Henry Molaison and the study of memory : Henry Molaison lost his memory and suffered from debilitating amnesia. He suffered from childhood epilepsy, and medical professionals attempted to remove the part of his brain that was causing his seizures. He had a portion of his brain removed, but it completely took away his ability to hold memories. Even though he went on to live until the age of 82, he was always forced to live in the present moment, as he was completely unable to form new memories.

Case study FAQs

When should you do a case study.

There are several scenarios when conducting a case study can be beneficial. Case studies are often used when there's a "why" or "how" question that needs to be answered. Case studies are also beneficial when trying to understand a complex phenomenon, there's limited research on a topic, or when you're looking for practical solutions to a problem.

How can case study results be used to make business decisions?

You can use the results from a case study to make future business decisions if you find yourself in a similar situation. As you assess the results of a case study, you can identify best practices, evaluate the effectiveness of an intervention, generate new and creative ideas, or get a better understanding of customer needs.

How are case studies different from other research methodologies?

When compared to other research methodologies, such as experimental or qualitative research methodology, a case study does not require a representative sample. For example, if you are performing quantitative research, you have a lot of subjects that expand your sample size. If you are performing experimental research, you may have a random sample in front of you. A case study is usually designed to deliberately focus on unusual situations, which allows it to shed new light on a specific business research problem.

Writing multiple case studies for your business

If you're feeling overwhelmed by the idea of writing a case study and it seems completely foreign, then you aren't alone. Writing a case study for a business is a very big deal, but fortunately, there is help available because an example of a case study doesn't always help.

Mailchimp, a well-known marketing company that provides comprehensive marketing support for all sorts of businesses, can assist you with your case study, or you can review one of their own recently published examples.

Mailchimp can assist you with developing the most effective content strategy to increase your chances of being as successful as possible. Mailchimp's content studio is a great tool that can help your business immensely.

• Create an observation plan: I will create a plan for observing the selected sample. This plan should include the time and location of the observations, as well as the specific tasks that will be observed.
• Conduct observations: I will observe the selected sample, recording the time taken to complete each task, as well as any other relevant data.
• Document findings: I will carefully document the findings of the time study. This will include the time taken to complete each task, as well as any other relevant observations made during the study.

It’s important to remember that these steps should be followed carefully and accurately in order to gather accurate and reliable data. Any errors or inaccuracies in the data could lead to incorrect conclusions, which could ultimately impact the overall effectiveness of the time study.

Analyzing Time Study Data: Techniques and Tools

Once the data collection phase of a time study is complete, the next step is to analyze the data to identify areas for improvement. There are several techniques and tools available to help with this process.

Statistical analysis software: This type of software can help to identify patterns and trends in the data. It can also perform complex calculations to determine averages, standard deviations, and other statistical measures.

Productivity metrics: These metrics provide insight into how efficiently tasks are being completed. They can include metrics such as cycle time, throughput, and work-in-progress.

When analyzing time study data, it is important to look for patterns and trends that may indicate areas for improvement. For example, if a certain task consistently takes longer than expected, it may be worthwhile to investigate the root cause of the delay and consider implementing changes to improve efficiency.

“Analyzing time study data can provide valuable insights into inefficiencies and areas for improvement in the workplace.”

It is also important to consider the context in which the data was collected. For example, if the data was collected during a particularly busy period, it may not be representative of typical performance. Taking this into account can help to ensure that any changes made based on the analysis of the data are appropriate and effective.

Overall, analyzing time study data can provide valuable insights into inefficiencies and areas for improvement in the workplace. By using the right tools and techniques, and carefully considering the context in which the data was collected, it is possible to identify opportunities for improvement and make meaningful changes that can lead to increased efficiency and productivity.

Interpreting Results: Identifying Inefficiencies and Improvement Opportunities

Now that I have collected and analyzed the data from my time study, it’s time to interpret the results. My main goal is to identify inefficiencies and improvement opportunities in the workplace, so that I can implement changes that will increase efficiency and productivity.

One of the first things I need to do is look for patterns in the data. Are there any tasks that consistently take longer than they should? Are there any employees who are consistently slower than others? These patterns can help me pinpoint areas where improvements can be made.

It’s important to not just focus on the results themselves, but also to understand the underlying causes of the inefficiencies. For example, if a task takes longer than it should because of a faulty machine, simply speeding up the employee won’t solve the problem. Instead, I need to address the root cause by repairing or replacing the machine.

I can also use work measurement techniques to identify bottlenecks in the workflow. This can help me identify areas where a small change could have a big impact on overall efficiency.

Finally, I need to prioritize the improvement opportunities based on their potential impact and feasibility. Some changes may require significant investment or a long time to implement, while others may be quick and easy to implement but have a smaller impact. By focusing on the most impactful and feasible changes first, I can maximize the efficiency gains from my time study.

Overall, interpreting the results of my time study is a crucial step in identifying inefficiencies and improvement opportunities in the workplace. By understanding the underlying causes of inefficiencies and prioritizing improvement opportunities based on their potential impact and feasibility, I can implement changes that will increase efficiency and productivity in the long run.

Implementing Changes: Strategies for Improving Efficiency

Now that I have analyzed the data and identified inefficiencies in my workplace, it’s time to implement changes that will lead to improved efficiency.

One strategy that has proven effective is process optimization. By reevaluating current processes, we can identify steps that are unnecessary or redundant and streamline the overall workflow. This can significantly reduce the amount of time and resources required to complete tasks.

Another important aspect is task allocation. By assigning tasks to individuals based on their skills and expertise, we can ensure that every task is completed efficiently and effectively. Clear communication of roles and responsibilities can also minimize confusion and eliminate duplication of effort.

Training programs are another effective way to improve efficiency. By investing in employee training, we can ensure that all staff members are equipped with the necessary skills and knowledge to complete tasks efficiently. This can also increase job satisfaction and motivation.

It is important to continuously monitor and evaluate the effectiveness of any changes made based on the time study results. Regular feedback mechanisms and evaluation processes need to be established to ensure that any improvements are sustained and further opportunities for optimization are identified.

By implementing these changes and continually striving for improvement, we can create a culture of efficiency and productivity that benefits both the organization and its employees.

Monitoring and Continuous Improvement: Sustaining Efficiency Gains

After implementing changes based on the findings of a time study, monitoring and continuous improvement are crucial for sustaining efficiency gains. It is essential to establish feedback mechanisms and regularly evaluate processes to ensure continued success.

One effective way to monitor efficiency is through productivity metrics . These metrics can track progress over time and identify any areas where improvement is needed. It is important to establish a baseline measurement before implementing changes and compare the results after changes have been made.

Regular evaluations and audits can also help to sustain efficiency gains. This involves reviewing processes and procedures to ensure they are still effective and identifying any new areas for improvement. The feedback received from employees and stakeholders is also valuable in identifying any issues or inefficiencies that may not have been previously identified.

Training programs should be implemented to maintain efficiency gains, especially for new employees or when changes have been made to existing processes. This ensures everyone is aware of the new procedures and can perform tasks effectively.

Overall, monitoring and continuous improvement are critical components of sustaining efficiency gains achieved through a time study. By establishing feedback mechanisms, regularly evaluating processes, and implementing training programs, efficiency gains can be maintained and improved upon over time.

Metrics details

The use of povidone-iodine for ocular surface asepsis is widespread for intravitreal injections. They became frequent procedures, leading to serial exposure of patients’ eyes to iodinated solutions. In this study, we investigate the changes in the ocular surface in patients submitted to repeated use of povidine for intravitreal injection of anti-VEGF asepsis, analyzing Ocular Surface Disease Index, non-invasive break up time, blinking quality, lipid layer, meniscus height and osmolarity.

This case-control study included 34 individuals (68 eyes), 14 males, 20 females aged 48 to 94. Inclusion criteria were individuals who received application of 2% povidone-iodine eyedrops for intravitreal injections treatment with the non-treated contralateral eye used as control. Ocular surface examinations were performed at a single occasion. A pre-intravitreal injection asepsis protocol with povidone-iodine was applied. All statistical analysis was performed using the STATA® 18.0 Software and a p-value = 0.05 was considered as the statistical significance value in all tests.

The median number of IVIs in treated eyes was 12 (range 6–20). The results in treated eyes compared with untreated eyes were respectively : median OSDI 16 (IQR 6–39) and 12.5 (IQR 8–39) ( p  = 0.380); mean NIBUT 10.30 (SD ± 2.62) and 10.78 (SD ± 2.92) ( s, p  = 0.476); median blinking quality 100 (IQR 100) and 100 (IQR 100 ) (%, p  = 0.188); median lipid layer 87 (IQR 77–90) and 86 (IQR 74–100) (nm, p  = 0.451); median meniscus height 0.22 (IQR 0.19-0,31) and 0.24 (IQR 0.20–0.27) (mm, p  = 0.862), median Meibomian gland atrophy 33 (IQR 24–45) and 31.5 (IQR 25–39) (%, p  = 0.524); and mean osmolarity 306.6 (SD ± 21.13) and 313.8 (SD ± 29) (mOsm, p  = 0.297). There was no statistically significant relationship between the repetitive use of 2% iodinated solution and signs or symptoms compatible with dry eye syndrome in this group of patients.

Conclusions

The findings suggest that 2% povidone iodine is a safe and efficacious agent for ocular surface antisepsis during intravitreal injections, not leading to substantial ocular surface modifications. This conclusion supports the continued use of povidone iodine in routine ophthalmic procedures without increased risk of inducing dry eye syndrome.

The use of povidone iodine (PVPI) for ocular surface asepsis is widespread, both for surgical procedures and intravitreal injections [ 1 , 2 , 3 , 4 , 5 ]. Surgeries for cataracts, glaucoma, and intravitreal injections have become common and frequent procedures in ophthalmology, leading to the serial exposure of patients’ eyes to iodine solutions [ 5 , 6 , 7 , 8 , 9 , 10 ]. These changes are directly associated with dry eye syndrome [ 11 , 12 ].

In particular, studies have demonstrated that intravitreal injections used to treat diabetic macular edema or age-related macular degeneration result in significant changes in the ocular surface, leading to dry eye syndrome and damage to homeostasis of the ocular surface [ 5 , 11 , 13 , 14 ].

Dry eye syndrome is a multifactorial disease of the ocular surface characterized by the loss of tear film homeostasis, hyperosmolarity, inflammation, damage and neurosensory abnormalities [ 11 , 15 , 16 , 17 , 18 ]. Its etiology is variable, ranging from nonspecific inflammation of the ocular surface to direct chemical or physical aggression, infections, and autoimmune diseases [ 11 , 12 , 15 , 19 ].

In addition to the most common symptoms, burning sensation, itching, speck, eye redness, excess tearing reflex, brightness sensitivity, and quality of vision loss are also frequent findings that affect efficiency at work and the quality of life of patients [ 11 , 12 , 15 , 19 , 20 ].

This study aimed to observe changes in the ocular surface and tear film due the serial use of 2% PVPI, the gold standard drug for asepsis of the ocular surface. As it is well known that pre-injection antisepsis of the ocular surface with PVPI has a toxic effect on the corneal epithelium, the aim is to identify changes in the tear film and ocular surface and avoid serious problem like dry eye syndrome [ 11 , 12 , 21 , 22 ].

A case-control study was conducted at the Ophthalmology and Psicology Clinic (APMTO MD) in Londrina, Paraná. The patients were recruited from the Retina and Vitreous Institute (AMBC MD) in Londrina, Paraná. The study included 34 individuals (68 eyes). 14 males, 20 females, aged 48 to 94 years. All participants signed the informed consent form, which allowed their participation in the study. Inclusion criteria were individuals who received application of 2% PVPI eyedrops for anti-VEGF IVIs treatment with the contralateral eye used as control, that had not been treated with any topical medication during the same period of applications and good comprehension of the Ocular Questionnaire Surface Disease Index (OSDI). Exclusion criteria were patients who could not understand the OSDI questionnaire; patients using antidepressant medicine, diuretics, sympathomimetics, eye drops for glaucoma, or eye lubricants; people with allergies to iodine; unfavorable clinical conditions to undergo the examination procedures for the study; inappropriate test quantity and quality; unsatisfactory images or unsatisfactory and inadequate data.

The study was approved by the Ethics and Research Committee Involving Human Beings of the State University of Londrina by N. 5.300.176.

The individuals underwent directed clinical and ophthalmological analysis, received explanations about the study, used their data, and signed consent forms. All clinical measures were performed using the IDRA equipment (SBSSISTEMI, Orbasano, Torino, Italy), at which time the OSDI questionnaire was also applied and tear osmolarity was collected using the I-PEN ® (I-MED PHARMA INC. Dollard-des-Ormeaux, QC, Canada). All examinations and administration of the questionnaire were performed by the same professional. No drops or medications that could cause changes in any subsequent measurements were used.

The variables analyzed were age, sex, date of the last PVPI application, number of PVPI applications, OSDI questionnaire, tear osmolarity, NBUT, tear film interferometry, tear meniscus height, percentage of meibomian gland loss, and blink quality. The sequence of procedures obeyed the following order: Explanation to the subject regarding the exams and questionnaire to which he would be submitted, guidance to the patient not to identify in any way the eye being treated and the eye not treated during data collection, nor during the questionnaire OSDI; patient positioning in the IDRA® equipment; capture of blinking quality video images; capture of tear film interferometry; capture of images to measure the height of the tear meniscus and immediate measurement; capture of tear film (NBUT); image capture for the percentage of meibomian gland loss by everting the lower eyelid with a cotton swab; positioning the patient outside the IDRA equipment; application of the I-PEN® electrode to capture tear osmolarity in the lower conjunctiva, first in the right eye, and subsequently in the left eye; application of the OSDI questionnaire.

All statistical analyses were performed using STATA® 18.0 Software and p-values ≤ 0.05 indicated statistical significance.

The Shapiro-Wilk test was used to verify data normality. Data that did not follow a normal distribution were analyzed using the Wilcoxon rank-sum test and were described as means and as medians and interquartile ranges. Data that showed normality were analyzed using the Student’s T test and presented as means and standard deviations. Descriptive, quantitative, and multivariate analyses compared treated (case) and untreated (control) eyes.

The average number of IVIs in treated eyes was 12 (range 6–20). The results in treated eyes compared with untreated eyes were respectively: median OSDI 16 (IQR 6–39) and 12.5 (IQR 8–39) ( p  = 0.380); mean NIBUT 10.30 (SD ± 2,62) and 10.78 (SD ± 2.92) ( s, p  = 0.476); median blinking quality 100 (IQR 100) and 100 (IQR 100 ) (%, p  = 0.188); median lipid layer 87 (IQR 77–90) and 86 (IQR 74–100) (nm, p  = 0.451); median meniscus height 0,22 (IQR 0.19–0.31) and 0.24 (IQR 0.20–0.27) (mm, p  = 0.862), median Meibomian gland athrophy 33 (IQR 24–45) and 31.5 (IQR 25–39) (%, p  = 0.524); and mean osmolarity 306.6 (SD ± 21.13) and 313.8 (SD ± 29) (mOsm, p  = 0.297).). The results revealed that the use of 2% PVPI did not affect the analyzed variables in a statistically significant way. All data is summarized on Table  1 .

These results are disposable on fig 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 and 9 as annexed.

Through multivariate analysis, we obtained some interesting outcomes as follows:

When controlling for NIBUT, meibomian gland atrophy, number of applications, and days of the last application according to treatment, sex was an important variable in explaining the variability in the OSDI score (coef = 15.63 | p-value = 0.003). On average, controlling for the abovementioned variables, being female contributed to an increase in the OSDI to 15.63 points.

After controlling for meniscus height and age according to treatment, tear osmolarity contributed significantly to variability in the lipid layer (coef = -0.266, p  = 0.004). In this sense, the addition of one unit in tear osmolarity led to a -0.266 drop in the lipid layer.

After controlling for meniscus height, OSDI, days since the last application, age, and sex according to the treatment, these factors contributed significantly to the variability in the lipid layer [(coef = 0.562 | p-value = 0.004) (coef = − 5.622 | p-value = 0.048)]. In this sense, the addition of one year of age led to a decrease of -0.562 on average. For the same treatment group, female sex led to a decrease of -5,622.

Age, lipid layer, meniscus height, sex according to treatment, age according to treatment, and sex were important factors for explaining the variability in tear osmolarity.

We noticed that a greater age correlated with lower tear osmolarity. However, being in the treated group reduced the decrease in tear osmolarity with advancing age.

Being female implied higher tear osmolarity. However, the increase in tear osmolarity was smaller in the treated group.

A greater height of the lipid layer and meniscus correlated with lower tear osmolarity.

The present study showed that the use of topical PVPI at 2% did not cause significant damage to the ocular surface when the findings of the ocular surface and tear film analyses were used.

Our results contradict some existing data indicating the toxicity of long-term iodine use on the ocular surface; we found two statistically relevant results that the application of iodine may improve the stability of the tear film in the elderly and women, since the eyes in older individuals and female patients that received iodine showed a smaller increase in tear osmolarity [ 4 , 14 , 23 , 24 ].

Moreover, the results of this study corroborated some hypotheses that the use of PVPI could be positive in some dry eye disease diagnostic features, such as the improvement of the tear film meniscus height and the decrease of the tear film osmolarity [ 25 , 26 ].

A localized anti-inflammatory surface effect of the anti-VEGF agent used in intravitreous injections should be considered and assessed in further studies [ 22 , 25 ].

The literature review also shows that there was an improvement in the tear function of some patients who used iodine in ocular asepsis [ 25 , 26 , 27 ], perhaps due to an antimicrobial action preventing the proliferation of bacterial flora that could produce harmful enzymes or cause meibomitis and blepharitis [ 25 , 26 , 28 ].

The cell regeneration mechanism might have satisfactorily recomposed the ocular surface or the tear homeostasis might have compensates for the damage caused by iodine in the cells in question; furthermore, these are just hypotheses.

We also determined that the risk factors for dry eye disease, age and female sex [ 10 , 16 , 29 , 30 ], were associated with the observed clinical data: greater ages lower the height of the tear meniscus, the greater the tear osmolarity, and the smaller the lipid layer of the tear film. The female sex was also associated with higher OSDI scores and fewer tear film lipid layers.

Regardless of the cause or consequence, the osmolarity and lipid layer of the tear film were inversely proportional.

Through multivariate analysis, we determined that the risk factors for dry eye syndrome, age, and female sex correlated with worse results in the tear meniscus measurement tests, OSDI questionnaire, and tear film interferometry, corroborating the literature implicating them as risk factors for dry eye disease [ 20 , 30 , 31 ].

Moreover, due to the sample size, false negatives, or simply because in practice, iodine in the amount and frequency used does not lead to histological damage that may reflect functional changes. The results did not discourage the use of iodine for ocular asepsis but also did not indicate its use for protocols with higher concentrations or more applications than those used in current protocols.

The strengths of the study are as follows: the same patient was the control and treated group, avoiding any environmental or medical bias. The number of injections administered was higher than that reported in other studies. No drops were used during the examination to avoid artificial changes to the tear film.

The limitations of this study were as follows: the study had a small sample size of 34 patients, resulting in 68 eyes being analyzed, which may have caused an analysis bias when using these data in the general population. We must remember that the analyzed population was from southern Brazil and had mostly descended from Italian, German, Spanish, and Portuguese immigrants; therefore, these data may only reflect the specific epidemiology of this population. The meibomian glands analyzed were located in the inferior tarsus.

The use of iodine on the ocular surface was not significantly associated with any of the evaluated parameters. There were no statistically significant correlations between the tests applied to the case eyes. The current study indicates that the application of 2% topical povidone-iodine (PVPI) does not inflict significant damage to the ocular surface, as evidenced by the analyses of the ocular surface and tear film. Notable strengths of this study include the use of the same patient as both the control and the treated subject, which minimizes potential biases from environmental or medical factors. Additionally, the absence of any artificial agents during the examination ensures that the tear film remains unaltered.

Contrary to previous concerns regarding the long-term toxicity of iodine on the ocular surface, our findings suggest potential benefits of iodine application in stabilizing the tear film, particularly in older individuals and female patients. This is supported by a smaller increase in tear osmolarity in these groups following iodine application. Furthermore, the study corroborates hypotheses that PVPI may positively affect certain Dry Eye Disease diagnostic features, such as improved tear film meniscus height and reduced tear film osmolarity.
