Introduction to Eight Disciplines of Problem Solving (8D)

The Eight Disciplines of Problem Solving (8D) is a problem solving methodology designed to find the root cause of a problem, devise a short-term fix and implement a long-term solution to prevent recurring problems. When it’s clear that your product is defective or isn’t satisfying your customers, an 8D is an excellent first step to improving Quality and Reliability.

Ford Motor Company developed this problem solving methodology, then known as Team Oriented Problem Solving (TOPS), in the 1980s. The early usage of 8D proved so effective that it was adopted by Ford as the primary method of documenting problem solving efforts, and the company continues to use 8D today.

8D has become very popular among manufacturers because it is effective and reasonably easy to teach. Below you’ll find the benefits of an 8D, when it is appropriate to perform and how it is performed.

What is Eight Disciplines of Problem Solving (8D)

The 8D problem solving process is a detailed, team oriented approach to solving critical problems in the production process. The goals of this method are to find the root cause of a problem, develop containment actions to protect customers and take corrective action to prevent similar problems in the future.

The strength of the 8D process lies in its structure, discipline and methodology. 8D uses a composite methodology, utilizing best practices from various existing approaches. It is a problem solving method that drives systemic change, improving an entire process in order to avoid not only the problem at hand but also other issues that may stem from a systemic failure.

8D has grown to be one of the most popular problem solving methodologies used for Manufacturing, Assembly and Services around the globe. Read on to learn about the reasons why the Eight Disciplines of Problem Solving may be a good fit for your company.

Why Apply Eight Disciplines of Problem Solving (8D)

The 8D methodology is so popular in part because it offers your engineering team a consistent, easy-to-learn and thorough approach to solving whatever problems might arise at various stages in your production process. When properly applied, you can expect the following benefits:

• Improved team oriented problem solving skills rather than reliance on the individual
• Increased familiarity with a structure for problem solving
• Creation and expansion of a database of past failures and lessons learned to prevent problems in the future
• Better understanding of how to use basic statistical tools required for problem solving
• Improved effectiveness and efficiency at problem solving
• A practical understanding of Root Cause Analysis (RCA)
• Problem solving effort may be adopted into the processes and methods of the organization
• Improved skills for implementing corrective action
• Better ability to identify necessary systemic changes and subsequent inputs for change
• More candid and open communication in problem solving discussion, increasing effectiveness
• An improvement in management’s understanding of problems and problem resolution

8D was created to represent the best practices in problem solving. When performed correctly, this methodology not only improves the Quality and Reliability of your products but also prepares your engineering team for future problems.

When to Apply Eight Disciplines of Problem Solving (8D)

The 8D problem solving process is typically required when:

• Safety or Regulatory issues has been discovered
• Customer complaints are received
• Warranty Concerns have indicated greater-than-expected failure rates
• Internal rejects, waste, scrap, poor performance or test failures are present at unacceptable levels

How to Apply Eight Disciplines of Problem Solving (8D)

The 8D process alternates inductive and deductive problem solving tools to relentlessly move forward toward a solution. The Quality-One approach uses a core team of three individuals for inductive activities with data driven tools and then a larger Subject Matter Expert (SME) group for the deductive activities through brainstorming, data-gathering and experimentation.

D0: Prepare and Plan for the 8D

Proper planning will always translate to a better start. Thus, before 8D analysis begins, it is always a good idea to ask an expert first for their impressions. After receiving feedback, the following criterion should be applied prior to forming a team:

Collect information on the symptoms

Use a Symptoms Checklist to ask the correct questions

Identify the need for an Emergency Response Action (ERA), which protects the customer from further exposure to the undesired symptoms

D1: Form a Team

A Cross Functional Team (CFT) is made up of members from many disciplines. Quality-One takes this principle one step further by having two levels of CFT:

• The Core Team Structure should involve three people on the respective subjects: product, process and data
• Additional Subject Matter Experts are brought in at various times to assist with brainstorming, data collection and analysis

Teams require proper preparation. Setting the ground rules is paramount. Implementation of disciplines like checklists, forms and techniques will ensure steady progress.  8D must always have two key members: a Leader and a Champion / Sponsor:

• The Leader is the person who knows the 8D process and can lead the team through it (although not always the most knowledgeable about the problem being studied)
• The Champion or Sponsor is the one person who can affect change by agreeing with the findings and can provide final approval on such changes

D2: Describe the Problem

The 8D method’s initial focus is to properly describe the problem utilizing the known data and placing it into specific categories for future comparisons. The “Is” data supports the facts whereas the “Is Not” data does not. As the “Is Not” data is collected, many possible reasons for failure are able to be eliminated. This approach utilizes the following tools:

• Problem Statement
• Affinity Diagram (Deductive tool)
• Fishbone/Ishikawa Diagram (Deductive tool)
• Problem Description

D3: Interim Containment Action

In the interim, before the permanent corrective action has been determined, an action to protect the customer can be taken. The Interim Containment Action (ICA) is temporary and is typically removed after the Permanent Correct Action (PCA) is taken.

• Verification of effectiveness of the ICA is always recommended to prevent any additional customer dissatisfaction calls

D4: Root Cause Analysis (RCA) and Escape Point

The root cause must be identified to take permanent action to eliminate it. The root cause definition requires that it can be turned on or off, at will. Activities in D4 include:

• Comparative Analysis listing differences and changes between “Is” and “Is Not”
• Development of Root Cause Theories based on remaining items
• Verification of the Root Cause through data collection
• Review Process Flow Diagram for location of the root cause
• Determine Escape Point, which is the closest point in the process where the root cause could have been found but was not

D5: Permanent Corrective Action (PCA)

The PCA is directed toward the root cause and removes / changes the conditions of the product or process that was responsible for the problem. Activities in D5 include:

• Establish the Acceptance Criteria which include Mandatory Requirements and Wants
• Perform a Risk Assessment /  Failure Mode and Effects Analysis (FMEA) on the PCA choices
• Based on risk assessment, make a balanced choice for PCA
• Select control-point improvement for the Escape Point
• Verification of Effectiveness for both the PCA and the Escape Point are required

D6: Implement and Validate the Permanent Corrective Action

To successfully implement a permanent change, proper planning is essential. A project plan should encompass: communication, steps to complete, measurement of success and lessons learned. Activities in D6 include:

• Develop Project Plan for Implementation
• Communicate the plan to all stakeholders
• Validation of improvements using measurement

D7: Prevent Recurrence

D7 affords the opportunity to preserve and share the knowledge, preventing problems on similar products, processes, locations or families. Updating documents and procedures / work instructions are expected at this step to improve future use. Activities in D7 include:

• Review Similar Products and Processes for problem prevention
• Develop / Update Procedures and Work Instructions for Systems Prevention
• Capture Standard Work / Practice and reuse
• Assure FMEA updates have been completed
• Assure Control Plans have been updated

D8: Closure and Team Celebration

Teams require feedback to allow for satisfactory closure. Recognizing both team and individual efforts and allowing the team to see the previous and new state solidifies the value of the 8D process. Activities in D8 include:

• Archive the 8D Documents for future reference
• Document Lessons Learned on how to make problem solving better
• Before and After Comparison of issue
• Celebrate Successful Completion

8D and Root Cause Analysis (RCA)

The 8D process has Root Cause Analysis (RCA) imbedded within it. All problem solving techniques include RCA within their structure. The steps and techniques within 8D which correspond to Root Cause Analysis are as follows:

• Problem Symptom is quantified and converted to “Object and Defect”
• Problem Symptom is converted to Problem Statement using Repeated Whys
• Possible and Potential Causes are collected using deductive tools (i.e. Fishbone or Affinity Diagram)
• Problem Statement is converted into Problem Description using Is / Is Not
• Problem Description reduces the number of items on the deductive tool (from step 3)
• Comparative Analysis between the Is and Is Not items (note changes and time)
• Root Cause theories are developed from remaining possible causes on deductive tool and coupled with changes from Is / Is Not
• Compare theories with current data and develop experiments for Root Cause Verification
• Test and confirm the Root Causes

Example: Multiple Why Technique

The Multiple / Repeated Why (Similar to 5 Why) is an inductive tool, which means facts are required to proceed to a more detailed level. The steps required to determine problem statement are:

• Problem Symptom is defined as an Object and Defect i.e. “Passenger Injury”
• Why? In every case “SUV’s Roll Over”
• Why? In every case, it was preceded by a “Blown Tire”
• Why? Many explanations may be applied, therefore the team cannot continue with another repeated why past “Blown Tire”
• Therefore, the Problem Statement is “Blown Tire”
• Why? Low (Air) Pressure, Tire Defect (Degradation of an Interface) and High (Ambient) Temperature
• Counter measures assigned to low pressure and tire defect

This example uses only 4 of the 5 Whys to determine the root causes without going further into the systemic reasons that supported the failure. The Repeated Why is one way to depict this failure chain. Fault Tree Analysis (FTA) could also be used.

What is 8D? A template for efficient problem-solving

How you respond when problems arise is one of the most defining qualities of a manager. Luckily, there are tools you can use to master problem-solving. The 8D method of problem-solving combines teamwork and basic statistics to help you reach a logical solution and prevent new issues from arising.

You’ve spent months overseeing the development of your company's newest project. From initiation, planning, and execution, you’re confident this may be your best work yet.

Until the feedback starts rolling in.

There’s no sugar-coating it—things don’t always go as planned. But production or process issues are hardly a signal to throw in the towel. Instead, focus on honing your problem-solving skills to find a solution that keeps it from happening again. 

The 8D method of problem solving emphasizes the importance of teamwork to not only solve your process woes but prevent new ones from occurring. In this guide, we’ll break down what 8D is, how to use this methodology, and the benefits it can give to you and your team. Plus, get an 8D template to make solving your issue easier.

What is 8D?

The eight disciplines (8D) method is a problem-solving approach that identifies, corrects, and eliminates recurring problems. By determining the root causes of a problem, managers can use this method to establish a permanent corrective action and prevent recurring issues. 

How do you use the 8D method?

The 8D method is a proven strategy for avoiding long-term damage from recurring problems. If you’re noticing issues in your workflow or processes, then it’s a good time to give this problem-solving method a try. 

To complete an 8D analysis, follow “the eight disciplines” to construct a statistical analysis of the problem and determine the best solution.

The eight disciplines of problem-solving

8D stands for the eight disciplines you will use to establish an 8D report. As you may notice, this outline starts with zero, which makes nine total disciplines. The “zero stage” was developed later as an initial planning stage. 

To illustrate these steps, imagine your organization experienced a decline in team innovation and productivity this past year. Your stakeholders have noticed and want to see changes implemented within the next six months. Below, we’ll use the 8D process to uncover a morale-boosting solution.

D0: Prepare and plan

Before starting the problem-solving process, evaluate the problem you want to solve. Understanding the background of the problem will help you identify the root cause in later steps. 

Collect information about how the problem has affected a process or product and what the most severe consequences may be. Planning can include:

Gathering data

Determining the prerequisites for solving the problem

Collecting feedback from others involved

If we look back at our example, you may want to figure out whether this decline in morale is organization-wide or only applies to a few departments. Consider interviewing a few employees from different departments and levels of management to gain some perspective. Next, determine what knowledge and skills you will need to solve this lapse in productivity. 

D1: Form your team

Create a cross-functional team made up of people who have knowledge of the various products and workflows involved. These team members should have the skills needed to solve the problem and put corrective actions in place. 

Steps in this discipline may include:

Appointing a team leader

Developing and implementing team guidelines

Determining team goals and priorities

Assigning individual roles

Arranging team-building activities

From our example, a solid team would consist of people with first-hand experience with the issues—like representatives from all departments and key people close to workshop-level work. You may also want to pull someone in from your HR department to help design and implement a solution. Most importantly, make sure the people you choose want to be involved and contribute to the solution.

D2: Identify the problem

You may have a good understanding of your problem by now, but this phase aims to break it down into clear and quantifiable terms by identifying the five W’s a and two H’s (5W2H):

Who first reported the problem?

What is the problem about?

When did it occur and how often?

Where did it occur (relating to the sector, supplier, machine, or production line involved)?

Why is solving the problem important?

How was the problem first detected?

How many parts/units/customers are affected?

Use your team’s insights to answer these questions. From our example, your team may conclude that: 

Employees feel overwhelmed with their current workload. 

There is no real structure or opportunity to share new ideas.

Managers have had no training for meetings or innovation settings.

Disgruntled employees know they can achieve more—and want to achieve more—even if they seem disengaged.

Once you answer these questions, record an official problem statement to describe the issue. If possible, include photos, videos, and diagrams to ensure all parties have a clear understanding of the problem. It may also help to create a flowchart of the process that includes various steps related to the problem description.

D3: Develop an interim containment plan

Much like we can expect speedy first aid after an accident, your team should take immediate actions to ensure you contain the problem—especially if the problem is related to customer safety. 

An interim containment plan will provide a temporary solution to isolate the problem from customers and clients while your team works to develop a permanent corrective action. This band-aid will help keep your customers informed and safe—and your reputation intact.

Because your findings revealed workers were overworked and managers lacked training, your team suggests scheduling a few mandatory training sessions for leaders of each department covering time and stress management and combating burnout . You may also want to have a presentation outlining the topics of this training to get key managers and stakeholders interested and primed for positive upcoming changes. 

D4: Verify root causes and escape points

Refer back to your findings and consult with your team about how the problem may have occurred. The root cause analysis involves mapping each potential root cause against the problem statement and its related test data. Make sure to test all potential causes—fuzzy brainstorming and sloppy analyses may cause you to overlook vital information. 

In our example, focus on the “why” portion of the 5W2H. You and your team identify six root causes:

Managers have never had any training

There is a lack of trust and psychological safety

Employees don’t understand the objectives and goals

Communication is poor

Time management is poor

Employees lack confidence

In addition to identifying the root causes, try to pinpoint where you first detected the problem in the process, and why it went unnoticed. This is called the escape point, and there may be more than one. 

D5: Choose permanent corrective actions

Work with your team to determine the most likely solution to remove the root cause of the problem and address the issues with the escape points. Quantitatively confirm that the selected permanent corrective action(s) (PCA) will resolve the problem for the customer. 

Steps to choosing a PCA may include:

Determining if you require further expertise

Ensuring the 5W2Hs are defined correctly

Carrying out a decision analysis and risk assessment

Considering alternative measures

Collecting evidence to prove the PCA will be effective

Your team decides to roll out the training used in the interim plan to all employees, with monthly company-wide workshops on improving well-being. You also plan to implement meetings, innovation sessions, and team-coaching training for managers. Lastly, you suggest adopting software to improve communication and collaboration. 

D6: Implement your corrective actions

Once all parties have agreed on a solution, the next step is to create an action plan to remove the root causes and escape points. Once the solution is in effect, you can remove your interim containment actions.

After seeing success with the training in the interim phase, your stakeholders approve all of your team’s proposed PCAs. Your representative from HR also plans to implement periodic employee wellness checks to track employee morale .

To ensure your corrective action was a success, monitor the results, customer, or employee feedback over a long period of time and take note of any negative effects. Setting up “controls” like employee wellness checks will help you validate whether your solution is working or more needs to be done. 

D7: Take preventive measures

One of the main benefits of using the 8D method is the improved ability to identify necessary systematic changes to prevent future issues from occurring. Look for ways to improve your management systems, operating methods, and procedures to not only eliminate your current problem, but stop similar problems from developing later on.

Based on our example, the training your team suggested is now adopted in the new manager onboarding curriculum. Every manager now has a “meeting system” that all meetings must be guided by, and workloads and projects are managed as a team within your new collaboration software . Innovation is improving, and morale is at an all-time high!

D8: Celebrate with your team

The 8D method of problem-solving is impossible to accomplish without dedicated team members and first-class collaboration. Once notes, lessons, research, and test data are documented and saved, congratulate your teammates on a job well done! Make an effort to recognize each individual for their contribution to uncovering a successful solution.

This is a formal report that can be used as a means of communication within companies, which makes for transparent problem-solving that you can apply to the entire production or process chain.

Benefits of using the 8D method

The 8D method is one of the most popular problem-solving strategies for good reason. Its strength lies in teamwork and fact-based analyses to create a culture of continuous improvement —making it one of the most effective tools for quality managers. The benefits of using the 8D method include: 

Improved team-oriented problem-solving skills rather than relying on an individual to provide a solution

Increased familiarity with a problem-solving structure

A better understanding of how to use basic statistical tools for problem-solving

Open and honest communication in problem-solving discussions

Prevent future problems from occurring by identifying system weaknesses and solutions

Improved effectiveness and efficiency at problem-solving

Better collaboration = better problem solving

No matter how good a manager you are, production and process issues are inevitable. It’s how you solve them that separates the good from the great. The 8D method of problem solving allows you to not only solve the problem at hand but improve team collaboration, improve processes, and prevent future issues from arising.

8D Problem Solving Report

8D is a problem solving method used globally, mainly in manufacturing industry by Quality Engineers and Operations managers. The purpose of 8D problem solving method is to identify, correct and prevent problems affecting customers and operational efficiency. It is a problem solving approach similar to PDCA cycle (Plan – Do – Check – Act).

8D stands for 8 Disciplines. It is a methodology that emphasizes “No problem should be repeated but fixed permanently”.

8D Problem Solving Method originally evolved during Second World War. But it became an official methodology in 1974, when it was used by US Government for its Military Operations as ‘Military Standard 1520’. Later it was adapted and popularized by Ford Motors with slight modification in the methodology.

As the name indicates 8D has 8 disciplines that any process or operations should follow to solve the problems occurring. The outcome of 8D is a report called ‘8D Report’ that records the problems, root cause(s) and corrective and preventive actions.

The below are the D’s in 8D approach:

Figure 1: 8D Problem Solving Approach

1D  – Team Formation: The first and foremost step not only in 8D but also in any other initiative or project is Team Formation, for any initiative cannot be successful without a right team. The team selected should be committed, competent, co-ordinated, cross-functional with representation from all teams, and should be knowledgeable in 8D methodology.

2D – Problem Description: After selecting the team, our concentration should be on detailing the problem. The team should collect details about the problem, for completely understanding the depth of the problem. All details should be data and fact based.

3D – Interim Containment Actions: Once the problem is described, before heading up to problem solving, the team should fix the effect of the problem, especially on customers. It might involve actions like isolating the items affected, replacing defective parts, before it reaches the customers. This step is mainly to prevent the problem from reaching the market and customers, which might become a competitive disadvantage and reduce customer loyalty.

4D – Root Cause Analysis: After taking containment actions, the team should involve in identifying the root cause(s) for the problem. Methods and tools like 5-Why Analysis , Fishbone diagram , Pareto Analysis , 7 Old QC tools , New QC tools etc. can be used for identifying the root cause. An important point to be noted is: Whatever method is used for RCA , it should be data & fact based.

5D – Formulate Corrective Actions: After successfully arriving at the root cause, the team should formulate corrective actions to be taken to correct the problem. Tools like Brain storming, Affinity diagram etc. can be used.

6D – Validate Corrective Actions: After arriving at the corrective actions, the team should validate whether the solutions are effective. There are several tools like Accelerated life testing , simulation etc. available for this purpose. Then the solution can be implemented in the process. The solution approach from step 4-6 should be repeated until the problem is completely eliminated.

7D – Preventive Action: Identifying and implementing corrective actions is only a temporary solution that keeps the system running or is like ‘Living with the problem by taking counter measures’. The permanent solution is to identify a potential long term solution that will not allow the problem (similar problems) from occurring into the system again. Sometimes corrective action will be a costly, time being measure. Preventive action makes changes in the system, upstream or downstream processes so that the entire system is modified or aligned for ‘Problem Free’ operations.

8D – Team and Individual Recognition: Once the problem is completely solved, the team and the extra-ordinary contributors must be rewarded and recognized appropriately. This will act as a motivation factor for other employees.

These are the steps of 8D methodology. To summarize, 8D is a holistic, systematic and proven methodology for problem solving.

What is the 8D Problem Solving? And How to use the 8D Report?

The 8D problem-solving process (also known as the 8 Disciplines) is very different from previous processes we explored previously, such as the Double Diamond process or the IBM Design Thinking. The 8D process works in a rigid standardised nature to address the crisis caused by problems. The 8D process aims to walk with the team to highlight the problem, its root causes and propose a long-term solution. The process is documented in an 8D report which includes details of each of the eight stages. At the end of this article, we will explore an example report, and you can find a free 8D report template to download.

In times of crisis, companies face the challenge of analysing and solving problems efficiently in a short time to save developed projects. Problem-solving techniques such as the  TRIZ method  and  Hurson’s Production Thinking Model  allow companies to overcome crises and solve problems using less effort and time.

Brief History of the 8D Problem Solving

The 8D method was first implemented by the US government during WW II as a military standard and was referred to as the Army Directive 1520, “Remedies and disposal of nonconforming materials.” In 1987, the demand for a team-oriented problem-solving method increased among the management organisation in the automotive industry to find a way to eliminate recurring issues.

Ford Motor Company published their manual,  Team Oriented Problem Solving (TOPS),  which includes their 8 Disciplines of the problem-solving process. The process was initially used to deal with quality control and safety issues inside the company but later expanded its role to a team approach problem-solving method. The 8D process is employed by engineers and designers to identify, analyse, and correct problems by eliminating the primary source that caused the problem.

So, what are the eight steps in the 8D methodology? The 8D problem solving process includes 8 Disciplines. In the mid-90s, a D0 step for planning was added to the process. The 8D steps include the following:

• D1: Team formation
• D2: Describe the problem
• D3: Develop a temporary containment plan
• D4: Determine and verify root causes
• D5: Verify the permanent solution
• D6: Implement the permanent solution
• D7: Prevent recurrence
• D8: Congratulate your team

The 8 Disciplines aim to achieve the following targets while solving the specified problem:

• Think as a team while solving the problem
• Isolate the situation and understand its causes
• Identify the factors that contribute to the problem
• Provide a temporary solution to halt the impact of the problem
• Eliminate the causes of the problem and the factors contributing to it
• Prevent the problem from recurring

When Should the 8D Problem Solving be Used?

Based on the above targets, the 8D problem solving process is designed for complex problems whose solution exceeds the ability of one expert. Also, it aims to establish communication for problem resolution through different levels inside the company. In some situations, the consumer or the management team requests the application of the 8D process through several forms or documentation.

While 8D problem solving is suitable for recurring problems that may repeatedly occur within a project or company, it is not ideal for simple issues that can be solved quickly by individual efforts. The process is unsuitable for a problem that can be solved with a straightforward solution. The 8D process is designed for complex issues, which require several weeks to solve and the involvement of at least four people.

8D problem solving provides a systematic process to find and solve problems. Therefore, if the situation requires choosing between alternative solutions, 8D acknowledges that other tools may help solve the problem better than the 8D process.

How to Apply the 8D Problem Solving Process?

The steps below form the 8 Discipline process to achieve targeted problem solving through the eight steps.

This discipline is also known as the Pre 8D because it aims to understand the problem and determine if the 8D process is the correct method to use. At this stage, the team aims to answer general questions such as:

• Is this a new problem, or has it happened before?
• Is this a recurring problem?
• What is the history of this issue?
• What was the method used to solve the problem before?

At this stage, the target is to learn about the problem’s history and decide if the 8D process is the best tool to solve the problem.

D1: Team Formation

Thinking as a team can produce more efficient solutions than trying to solve a problem alone. The team includes all the stakeholders involved in the situation. The team communicates with each other and performs brainstorming to solve the problem (check  Design Thinking Tools: Reverse Brainstorming ). If the team does not know each other, the brainstorming time can be used to learn how to teach members to explore ideas together. Methods can be used in brainstorming sessions such as mind mapping , Six Thinking Hats , and  Lego Serious Play.

D2: Describe the Problem

After team formation, the second step is to understand the problem and its risks. This stage starts with a risk analysis to identify the situation and how it can affect the project flow. Several methods can be used to analyse the problem from different perspectives, including  SWOT analysis ,  SCAMPER technique , and similar tools. This stage is essential to building a clear vision of the problem and ensuring all stakeholders have the same understanding of the situation.

D3: Develop a Temporary Containment Plan

While solving the problem, there should be a temporary containment plan to prevent the problem from affecting the rest of the project or the final product. This temporary containment solution is a short-term operation such as adding more labour, increasing the quality measurements, applying a risk plan, etc.

It is essential to understand that the containment action is not the real solution and can only be used for the short term. Therefore, this action can be applied internally and not affect the process of reaching a permanent solution.

D4: Determine and Verify Root Causes

This stage aims to investigate the root causes of the problem; it can be considered the core of the 8D problem solving process. In many problems, what we see as causes are symptoms of other root causes. This misunderstanding can lead to inaccurate attempts at solutions that can have negative consequences in the future and leave the underlying problem unsolved.

An intensive investigation should be implemented because, in many cases, the root cause is hidden inside the process and covered by many symptoms, which is confusing. Some tools can be used to define the root causes of the problem, such as  brainstorming , statistical analysis, flow charts, audits, etc.

D5: Verify the Permanent Solution

Once the root cause is defined, the solution becomes apparent, and the team better understands how to solve the problem. However, the symptoms and other related factors may create difficulties deciding how best to apply the solution. So, these other factors should be considered when determining the permanent solution to the dilemma.

When choosing the permanent solution to the problem, it should meet the following criteria to ensure it is the ideal solution for the problem:

• The solution should be practical
• The solution should be feasible
• The solution should be cost-effective
• The solution should not fail during production
• The solution should be implemented in all affected facilities in the company

D6: Implement the Permanent Solution

Once the solution is approved, this step tends to work as an action plan. This plan aims to outline the steps to implement the solution. It is common to ask questions in this stage: What should be done? Who should be involved in the correction plan?

More documentation and detailed plans should be created if the solution is complex and needs further procedures. The method may include training the team and checking the plan’s progress for further development and improvement.

D7: Prevent Recurrence

Once the action plan is set and ready to be implemented, the team should establish a plan to prevent the problem from occurring in the future. The action plan should be tested and documented as part of the process to avoid the recurrence of the problem. Some of the tools that can achieve this goal are Control Charts, Capabilities Analysis, and Control Plans.

D8: Congratulate the Team

After completing the task and implementing the solution, the team deserves an acknowledgement of their work and a celebration. This event will positively impact the stakeholders and reflect recognition of employees’ efforts from the management inside the company.

How do you Write an 8D Report?

The primary documentation used in the problem solving process is the 8D report. Korenko et al. (2013) presented an example of the 8D problem-solving application, Application 8D Method For Problems Solving . After this example, you can find a free 8D Report template that you can download and use for both commercial and noncommercial applications. The first part of the report, D0, includes information about the problem and the project details related to the project. D1 section contains details of the team involved in the project, roles, titles and contact information. D2 part of the report includes a detailed description of the problem and possible visual images to show the problem clearly. The report can consist of the type of damage of the failure and the function where the problem occurs (Figure 2).  

D3 includes details of the temporary solution for the problem required to stop the damage rapidly. In this part, the temporary remedy is described, particularly the symptoms affect, the responsibility, and the validation of the action. In D4, the team uses a root-cause method such as the 5WHYs or the Cause-Effect analysis (Fish Bone method). These methods help the team to identify the root causes of the problem. In Figure 3, the 5WHYs method is used several times to identify the root cause of the problem. 

D5 of the report provides details about the permanent solution to fix the problem. Unlike the temporary solution, this aims to element the root causes of the problem. This section includes the procedure’s name, the reason to use it, the responsibility, the management approval to apply it and the expected date of completing the utilisation of the solution, as seen in Figure 4. In the following stage, D6, the team provides details on the implementation and validation of the permanent action.

D7 provides details about preventing the recurrent problem, such as the name of the action after the validation process in the previous stage. Also, this stage provides details of the cause behind this action and elements about its responsibility and implementing details. Finally, in D8, the report includes a summary of the procedure and the proper approvals related to the procedure implementation (Figure 5).

The 8D Problem Solving process provides a reliable and systematic method that ensures that the problems inside a company or project are solved by eliminating their root causes and preventing recurrence. However, it is most suitable for complex problems that can take weeks or even months to solve. Therefore, the first stage aims to determine if the 8D process is ideal for the problem or if more straightforward tools should be implemented. If the 8D problem solving method is appropriate for your business problem, you have a step-by-step template to guide you through your attempts to find a suitable solution to the obstacle you need to overcome.

8D Problem Solving Process

Solving major problems in a disciplined way.

Written by the Mind Tools Content Team

(Also known as Global 8D Problem Solving)

When your company runs into a major problem, you need to address it quickly. However, you also need to deal with it thoroughly and ensure that it doesn't recur – and this can take a lot of effort and elapsed time.

The 8D Problem Solving Process helps you do both of these seemingly-contradictory things, in a professional and controlled way. In this article, we'll look at the 8D Problem Solving Process, and we'll discuss how you can use it to help your team solve major problems.

Origins of the Tool

The Ford Motor Company® developed the 8D (8 Disciplines) Problem Solving Process, and published it in their 1987 manual, "Team Oriented Problem Solving (TOPS)." In the mid-90s, Ford added an additional discipline, D0: Plan. The process is now Ford's global standard, and is called Global 8D.

Ford created the 8D Process to help teams deal with quality control and safety issues; develop customized, permanent solutions to problems; and prevent problems from recurring. Although the 8D Process was initially applied in the manufacturing, engineering, and aerospace industries, it's useful and relevant in any industry.

The eight disciplines are shown in figure 1, below:

Figure 1: The 8D Problem Solving Process

The 8D Process works best in teams tasked with solving a complex problem with identifiable symptoms. However, you can also use this process on an individual level, as well.

Applying the Tool

To use the 8D Process, address each of the disciplines listed below, in order. Take care not to skip steps, even when time is limited; the process is only effective when you follow every step.

Discipline 0: Plan

Before you begin to assemble a team to address the problem, you need to plan your approach. This means thinking about who will be on the team, what your time frame is, and what resources you'll need to address the problem at hand.

Discipline 1: Build the Team

You should aim to put together a team that has the skills needed to solve the problem, and that has the time and energy to commit to the problem solving process.

Keep in mind that a diverse team is more likely to find a creative solution than a team of people with the same outlook (although if outlooks are too diverse, people can spend so much time disagreeing that nothing gets done).

Create a team charter that outlines the team's goal and identifies each person's role. Then, do what you can to build trust and get everyone involved in the process that's about to happen.

If your team is made up of professionals who haven't worked together before, consider beginning with team-building activities to ensure that everyone is comfortable working with one another.

Discipline 2: Describe the Problem

Once your team has settled in, describe the problem in detail. Specify the who, what, when, where, why, how, and how many; and use techniques like CATWOE and the Problem-Definition Process to ensure that you're focusing on the right problem.

Start by doing a Risk Analysis – if the problem is causing serious risks, for example, to people's health or life, then you need to take appropriate action. (This may include stopping people using a product or process until the problem is resolved.)

If the problem is with a process, use a Flow Chart , Swim Lane Diagram , or Storyboard to map each step out; these tools will help your team members understand how the process works, and, later on, think about how they can best fix it.

Discovering the root cause of the problem comes later in the process, so don't spend time on this here. Right now, your goal is to look at what's going wrong and to make sure that your team understands the full extent of the problem.

Discipline 3: Implement a Temporary Fix

Once your team understands the problem, come up with a temporary fix. This is particularly important if the problem is affecting customers, reducing product quality, or slowing down work processes.

Harness the knowledge of everyone on the team. To ensure that each person's ideas are heard, consider using brainstorming techniques such as Round Robin Brainstorming or Crawford's Slip Writing Method , alongside more traditional team problem solving discussions.

Once the group has identified possible temporary fixes, address issues such as cost, implementation time, and relevancy. The short-term solution should be quick, easy to implement, and worth the effort.

Discipline 4: Identify and Eliminate the Root Cause

Once your temporary fix is in place, it's time to discover the root cause of the problem.

Conduct a Cause and Effect Analysis to identify the likely causes of the problem. This tool is useful because it helps you uncover many possible causes, and it can highlight other problems that you might not have been aware of. Next, apply Root Cause Analysis to find the root causes of the problems you've identified.

Once you identify the source of the problem, develop several permanent solutions to it.

If your team members are having trouble coming up with viable permanent solutions, use the Straw Man Concept to generate prototype solutions that you can then discuss, tear apart, and rebuild into stronger solutions.

Discipline 5: Verify the Solution

Once your team agrees on a permanent solution, make sure that you test it thoroughly before you fully implement it, in the next step.

• Conducting a Failure Mode and Effects Analysis (FMEA) to spot any potential problems.
• Using Impact Analysis to make sure that there will be no unexpected future consequences.
• Using Six Thinking Hats to examine the fix from several different emotional perspectives.

Last, conduct a Blind Spot Analysis to confirm that you and your team haven't overlooked a key factor, or made an incorrect assumption about this solution.

Discipline 6: Implement a Permanent Solution

Once your team reaches a consensus on the solution, roll your fix out. Monitor this new solution closely for an appropriate period of time to make sure that it's working correctly, and ensure that there are no unexpected side effects.

Discipline 7: Prevent the Problem From Recurring

When you're sure that the permanent solution has solved the problem, gather your team together again to identify how you'll prevent the problem from recurring in the future.

You might need to update your organization's standards, policies, procedures, or training manual to reflect the new fix. You'll likely also need to train others on the new process or standard. Finally, you'll need to consider whether to change your management practices or procedures to prevent a recurrence.

Discipline 8: Celebrate Team Success

The last step in the process is to celebrate and reward your team's success . Say "thank you" to everyone involved, and be specific about how each person's hard work has made a difference. If appropriate, plan a party or celebration to communicate your appreciation.

Before the team disbands, conduct a Post-Implementation Review to analyze whether your solution is working as you thought, and to improve the way that you solve problems in the future.

In the late 1980s, Ford Motor Company developed the 8D (8 Disciplines) Problem Solving Process to help manufacturing and engineering teams diagnose, treat, and eliminate quality problems. However, teams in any industry can use this problem solving process.

The eight disciplines are:

• Build the Team.
• Describe the Problem.
• Implement a Temporary Fix.
• Identify and Eliminate the Root Cause.
• Verify the Solution.
• Implement a Permanent Solution.
• Prevent the Problem From Recurring.
• Celebrate Team Success.

The 8D Problem Solving Process is best used with a team solving complex problems; however, individuals can also use it to solve problems on their own.

Table of Contents

Eight Disciplines (8D) is a problem-solving methodology designed to address, correct, and eliminate recurring problems impacting business operations, manufacturing, and product development.

Developed by Ford Motor Company in the 1980s, the 8D method has since been widely adopted across various industries as a comprehensive quality and process improvement tool. It combines teamwork, analytical tools, and a systematic approach to identify, solve, and prevent problems.

How & When 8D Methodology is Used

The 8D methodology is used when a recurring or significant problem has been identified and needs a structured approach to resolve. It is advantageous in scenarios where the root cause of the problem is not immediately apparent and requires thorough analysis to identify.

Industries like automotive, manufacturing, aerospace, and healthcare, among others, leverage 8D for its systematic approach to problem-solving and its emphasis on prevention.

The process is typically initiated once a problem is recognized and can significantly impact quality, safety, customer satisfaction, or costs. The 8D approach is about resolving the issue at hand and implementing a continuous improvement system that prevents similar problems from occurring.

The Eight Disciplines Explained

The 8D methodology consists of the following steps:

D1: Establish the Team

The first formal step of the Eight Disciplines (8D) problem-solving methodology, D1, focuses on establishing the team that will work on identifying, analyzing, and solving the problem at hand. This step is critical to the success of the 8D process, as the team’s composition, skills, and collaboration will significantly impact the effectiveness of the problem-solving efforts. Here’s a detailed look at D1, including its objectives, key considerations, and best practices for assembling an effective team.

Objectives of D1

• Form a Cross-functional Team : The primary objective is to assemble a team with members from various departments or functions relevant to the problem. This diversity ensures a broad range of perspectives and expertise, facilitating a comprehensive understanding of the problem and the development of effective solutions.
• Define Roles and Responsibilities : Clearly outline each team member’s roles, responsibilities, and expectations. This clarity helps in ensuring accountability and efficient collaboration throughout the 8D process.
• Empower the Team : Equip the team with the authority, resources, and support needed to investigate the problem thoroughly and implement solutions effectively. This includes access to data, tools, and decision-making authority.

Key Considerations for Establishing the Team

• Expertise and Knowledge : Select members with the relevant technical knowledge, problem-solving skills, and experience related to the problem area. Including experts who understand the processes, products, or services involved is crucial.
• Interpersonal Skills : Consider potential team members’ interpersonal skills and teamwork capabilities. Effective communication, collaboration, and conflict-resolution skills are essential for the team’s success.
• Representation from Affected Areas : Ensure that the team includes representation from all areas affected by the problem. This can include manufacturing, quality assurance, engineering, customer service, and other relevant departments.
• Leadership : Appoint a team leader with strong leadership skills and the ability to guide the team through the 8D process. The team leader should be capable of facilitating meetings, keeping the team focused, and ensuring progress.

Best Practices for Assembling an Effective Team

• Size of the Team : Aim for a manageable team size, typically between 4 to 8 members. This size allows for diverse input while maintaining efficient communication and decision-making.
• Training : Provide training or orientation on the 8D methodology and problem-solving tools to team members unfamiliar with the process. This ensures that all members are aligned and can contribute effectively.
• Commitment and Availability : Ensure selected team members are available and committed to participating in the 8D process. This may require securing support from management to allocate time and resources for the team’s activities.
• Communication Plan : Establish a communication plan outlining how the team will communicate internally and with external stakeholders. Regular updates and meetings should be scheduled to keep everyone informed and engaged.

In summary, D1 is about carefully selecting and preparing a team with the right mix of skills, knowledge, and perspectives to tackle the problem effectively. A well-established team sets the foundation for a successful 8D process, enabling thorough analysis, creative solutions, and sustainable improvements.

D2: Describe the Problem

After establishing a well-composed team in D1, the Eight Disciplines (8D) problem-solving methodology progresses to D2, which focuses on accurately and comprehensively describing the problem. This step is crucial as it lays the foundation for understanding the issue and guides the subsequent steps in the 8D process. An effective problem description ensures that the team has a clear and shared understanding of what needs to be addressed. Here’s a closer look at D2, including its objectives, key elements, and best practices.

Objectives of D2

• Define the Problem Clearly : Provide a clear, concise description of the problem, emphasizing specific, measurable details about what is happening, where, when, and to what extent.
• Establish Baseline Data : Gather and document quantitative data related to the problem to establish a baseline for future comparisons. This data helps in understanding the severity, frequency, and trends of the problem.
• Identify the Impact : Assess and describe the impact of the problem on operations, quality, customer satisfaction, costs, and safety. Understanding the impact helps prioritize the problem-solving efforts.

Key Elements of an Effective Problem Description

• Specificity : Avoid vague descriptions. Be specific about the details of the problem, including the affected product or process, locations, time frames, and quantities.
• Quantitative Data : Use data and evidence to describe the problem. Quantifiable information such as defect rates, downtime, and customer complaints provides a clearer picture of the problem’s magnitude.
• Use of Visuals : Where possible, use charts, graphs, photographs, or diagrams to illustrate the problem. Visual aids can enhance understanding and communication among team members and stakeholders.
• 5W2H Method : Employ the 5W2H method (Who, What, Where, When, Why, How, How Much) to ensure a comprehensive description. While not all elements may be known at this stage, addressing as many as possible strengthens the problem statement.

Best Practices for Describing the Problem

• Involve Relevant Stakeholders : Engage with individuals who are directly affected by the problem or who have firsthand knowledge of it. Their insights can contribute to a more accurate and detailed problem description.
• Avoid Assuming Causes : Focus on describing the problem without jumping to conclusions about its causes. The analysis of root causes is addressed in later stages of the 8D process.
• Initial Problem Statement Revision : Be prepared to revise the problem statement as more information becomes available. An iterative approach ensures the problem description remains accurate and relevant throughout the process.
• Document Everything : Maintain thorough documentation of the problem description, including all data, visuals, and stakeholder inputs. This documentation will be invaluable as the team progresses through the 8D steps.

In summary, D2 is about defining the problem in clear, specific, and measurable terms, utilizing data and evidence to outline the scope and impact of the issue. A well-articulated problem statement is essential for guiding the team’s efforts in investigating root causes, developing corrective actions, and ultimately resolving the problem effectively.

D3: Develop Interim Containment Plan

Following the establishment of the team and the detailed description of the problem, the Eight Disciplines (8D) problem-solving methodology advances to D3, which involves developing an interim containment plan. This step is crucial for preventing the problem from causing further harm or spreading while the team works on identifying and implementing a permanent solution. Here’s a deeper look at D3, its objectives, key considerations, and best practices.

Objectives of D3

• Minimize Impact : Implement immediate, temporary measures to contain the problem, minimizing its impact on customers, operations, and quality.
• Prevent Spread : Ensure that the problem does not escalate or spread to other areas, processes, or products.
• Maintain Operations : Keep operations running as smoothly as possible while the team works on identifying and implementing a long-term solution.

Key Considerations for Developing an Interim Containment Plan

• Quick and Effective Measures : The containment actions should be quick to implement and effective in addressing the immediate impacts of the problem. They don’t have to be the long-term solution but should provide immediate relief.
• Assessment of Risks and Side Effects : Evaluate the potential risks and side effects of the containment actions. It’s vital to ensure that these actions do not introduce new problems or significantly disrupt operations.
• Resource Allocation : Determine what resources (e.g., personnel, equipment, materials) are needed to implement the containment actions and ensure they are readily available.

Best Practices for Interim Containment

• Identify Containment Actions : Containment actions can vary widely depending on the nature of the problem. Manufacturing issues might involve segregating and inspecting inventory to remove defective products. In service-oriented processes, it might entail additional checks or temporary manual oversight.
• Communication and Documentation : Clearly communicate the need for, and details of, the containment actions to all affected parties. Document all actions taken, including who is responsible for implementing and monitoring these actions’ effectiveness.
• Monitor and Adjust : Continuously monitor the effectiveness of the containment actions. Be prepared to adjust or implement additional measures if the problem persists or side effects are observed.
• Link to Root Cause Analysis : While D3 focuses on immediate containment, it should be implemented with an understanding that it is a temporary fix. Insights gained during this stage can be valuable for the root cause analysis in D4.

Example of Containment Actions

For a manufacturing defect identified in a product line, containment actions might include:

• Inspecting All Current Inventory : Perform a thorough inspection of all current inventory to identify and segregate any defective products.
• Halting Production : Temporarily stop production of the affected product line until the root cause is identified and addressed.
• Notifying Customers : If defective products have reached customers, inform them of the issue, and offer replacements, repairs, or refunds as appropriate.

In summary, D3 is about quickly responding to the problem with effective interim measures that contain its impact. These actions are crucial for maintaining customer trust and operational stability while the team works on a permanent solution. Properly executed, the containment plan sets the stage for a thorough analysis and resolution of the underlying issue in the subsequent steps of the 8D process.

D4: Determine Root Cause(s)

After establishing an interim containment plan to manage the immediate impacts of the problem, the Eight Disciplines (8D) problem-solving process moves to D4, which focuses on identifying the root cause(s) of the problem. This critical step involves a deep dive into the problem to understand why it occurred in the first place, setting the stage for developing effective, long-lasting solutions. Here’s a closer look at D4, including its objectives, methodologies, and best practices.

Objectives of D4

• Identify Underlying Causes : The primary objective of D4 is to determine the fundamental reasons behind the problem, going beyond superficial symptoms to understand the underlying causes.
• Systematic Analysis : Employ a systematic approach to analyze the problem and its contributing factors, ensuring that all possible causes are considered.
• Evidence-Based Conclusions : Base conclusions on data and evidence, rather than assumptions or speculation, to ensure that the identified root causes accurately represent the source of the problem.

Methodologies for Root Cause Analysis

Several tools and techniques can be employed during D4 to facilitate thorough and systematic root cause analysis:

• 5 Whys : A questioning technique used to drill down into the details of the problem and uncover the root cause by repeatedly asking “Why?” until the fundamental cause is identified. [ Learn More ]
• Ishikawa (Fishbone) Diagram : A visual tool that helps identify and categorize potential causes of a problem across various categories (e.g., People, Processes, Materials, Equipment), facilitating a comprehensive analysis.
• Pareto Analysis : A statistical technique that applies the 80/20 rule to identify the few critical causes that contribute to most of the problem, helping prioritize focus areas. [ Learn More ]
• Fault Tree Analysis (FTA) : A top-down, deductive analysis method used to explore the causes of a specific problem or undesired event.

Best Practices for Root Cause Analysis

• Cross-functional Collaboration : Engage team members from different functions or departments to ensure a broad perspective is considered during the analysis. Different viewpoints can uncover aspects of the problem that might otherwise be overlooked.
• Data Collection and Analysis : Gather and analyze data related to the problem, including historical data, to identify patterns, trends, and anomalies that might point to root causes.
• Verification of Root Causes : Before concluding the analysis, verify that the identified root causes, when addressed, would prevent the recurrence of the problem. This might involve experimentation, additional data analysis, or consulting with subject matter experts.
• Document Findings : Thoroughly document the analysis process, findings, and evidence supporting the identification of root causes. This documentation is crucial for justifying the corrective actions in later stages and for future reference.

Example of Root Cause Identification

If a manufacturing process is producing a high rate of defective products, root cause analysis might reveal that the root cause is outdated equipment that cannot maintain the necessary precision for production. Alternatively, the analysis might uncover that the real issue is a lack of operator training, leading to improper machine setup.

In summary, D4 is about rigorously identifying the root cause(s) of the problem through systematic analysis and evidence-based conclusions. Understanding the underlying reasons why a problem occurred is essential for developing effective corrective actions that prevent recurrence, setting the stage for D5, where these solutions are selected and planned.

D5: Choose and Verify Permanent Corrective Actions (PCAs)

After identifying the root cause(s) of the problem in D4, the Eight Disciplines (8D) problem-solving process progresses to D5. This crucial step involves selecting, verifying, and planning the implementation of permanent corrective actions (PCAs) to address the root causes identified. The goal is to ensure that the problem is resolved in a way that prevents its recurrence. Here’s a detailed look at D5, including its objectives, considerations, and best practices.

Objectives of D5

• Select Effective Solutions : Choose corrective actions that directly address the root causes of the problem to ensure that it is effectively resolved.
• Prevent Recurrence : Ensure that the chosen solutions not only fix the problem but also prevent it from happening again in the future.
• Consider Impact : Evaluate the potential impact of the corrective actions on other processes, systems, or products to avoid creating new problems.

Key Considerations for Choosing Corrective Actions

• Effectiveness : Assess the potential effectiveness of each corrective action in addressing the root cause. This often involves a cost-benefit analysis to determine the most efficient solution.
• Feasibility : Evaluate the feasibility of implementing each corrective action, considering factors such as time, resources, and organizational constraints.
• Side Effects : Consider any potential side effects or negative impacts of corrective actions on other processes or areas.

Best Practices for Selecting and Verifying PCAs

• Brainstorming and Collaboration : Engage the team in brainstorming sessions to generate a wide range of potential corrective actions. Collaboration ensures diverse perspectives and innovative solutions.
• Pilot Testing : Where feasible, conduct pilot tests of the proposed corrective actions. This allows the team to assess their effectiveness and make necessary adjustments before full-scale implementation.
• Stakeholder Input : Involve stakeholders, including those who will be affected by the corrective actions, in the selection process. Their insights can provide valuable input on the practicality and potential impact of the proposed solutions.
• Documentation : Thoroughly document the decision-making process, including the rationale for selecting specific corrective actions and the results of any tests or evaluations conducted.

Example of Verifying Corrective Actions

If the root cause of a manufacturing defect was identified as outdated equipment unable to maintain precision, a potential corrective action might be to upgrade or replace the equipment. Before implementing this solution across the board, a pilot test could be conducted with one production line to verify the effectiveness of the new equipment in reducing defects. The results would inform whether this solution should be applied more broadly or adjusted.

Implementation Planning

Once the corrective actions have been selected and verified, the next step is to plan their implementation. This involves:

• Developing a Detailed Action Plan : Outline the steps needed to implement the corrective actions, including timelines, responsibilities, and required resources.
• Setting Milestones and Metrics for Success : Establish clear milestones and performance metrics to monitor the effectiveness of the corrective actions over time.
• Communication : Communicate the plan and expected outcomes to all stakeholders, ensuring alignment and support for the implementation phase.

In summary, D5 is a critical step in the 8D process, where the team selects and verifies corrective actions that will effectively address the root causes of the problem. By carefully considering each solution’s impact, effectiveness, and feasibility, and involving stakeholders in the process, the team can ensure that the chosen actions will provide a lasting resolution to the problem, paving the way for successful implementation in D6.

D6: Implement and Validate Corrective Actions

Following the selection and verification of permanent corrective actions (PCAs) in D5, the Eight Disciplines (8D) problem-solving process moves on to D6, which focuses on implementing and validating these corrective actions. This crucial step ensures that the solutions are effectively put into place and that they effectively resolve the problem and prevent its recurrence. Here’s an in-depth look at D6, including its objectives, implementation strategies, and best practices for validation.

Objectives of D6

• Implement Solutions : Execute the plan developed in D5 to implement the corrective actions that address the root causes of the problem.
• Monitor Implementation : Closely monitor the implementation process to ensure corrective actions are executed as planned and identify any issues or barriers to successful implementation.
• Validate Effectiveness : Verify that the implemented corrective actions have effectively resolved the problem and that there are no unintended negative impacts on other processes or areas.

Strategies for Implementing Corrective Actions

• Detailed Implementation Plan : Utilize the detailed plan developed in D5, which outlines the steps, timelines, responsibilities, and resources required for implementation. This plan serves as a roadmap, guiding the implementation process.
• Communication and Training : Communicate the implementation plan to all relevant parties, ensuring everyone understands their role. Provide training or support as necessary to facilitate effective implementation.
• Resource Allocation : Ensure that all necessary resources, including personnel, equipment, and financial resources, are available and allocated to support the implementation of corrective actions.

Best Practices for Validating Corrective Actions

• Establish Validation Criteria : Define clear criteria for evaluating the success of the corrective actions. These criteria should be directly linked to the metrics and goals established during the planning phase.
• Collect and Analyze Data : Gather data to assess the effectiveness of the corrective actions. This may involve measuring performance indicators, conducting inspections, or gathering stakeholder feedback.
• Adjust and Optimize : If the data indicates that the corrective actions are not fully effective, or if there are unforeseen negative impacts, be prepared to make adjustments. This may involve revising the actions, implementing additional measures, or conducting further analysis to identify additional root causes.
• Document Results : Thoroughly document the implementation process, the validation efforts, and the outcomes. This documentation should include data analysis, adjustments, and final assessment of the effectiveness of corrective actions.

Example of Implementation and Validation

If the corrective action involved upgrading equipment to address manufacturing defects, the implementation phase would include purchasing and installing the new equipment, training operators on its use, and integrating it into the production process. Validation would involve monitoring defect rates before and after the implementation, assessing production efficiency, and gathering feedback from operators to ensure that the problem has been resolved and that no new issues are arising from the change.

In summary, D6 is about taking the corrective actions from plan to action, ensuring they are implemented effectively, and validating their success in solving the original problem. This step requires careful planning, coordination, and data-driven validation to confirm that the problem has been addressed and to prevent its recurrence, setting the stage for preventive measures in D7.

D7: Take Preventive Measures

After implementing and validating the effectiveness of the corrective actions in D6, the Eight Disciplines (8D) problem-solving process advances to D7. This step focuses on taking preventive measures to ensure that the problem and similar issues do not recur in the future. D7 is about embedding long-term solutions into the organization’s processes, systems, and culture. Here’s a detailed look at D7, including its objectives, key activities, and best practices.

Objectives of D7

• Prevent Recurrence : Establish measures that prevent the original problem and similar issues from occurring again in the future.
• Systemic Improvement : Identify and implement changes to systems, processes, and practices to improve overall quality and performance, based on the learnings from the problem-solving process.
• Enhance Organizational Learning : Promote a culture of continuous improvement and learning by sharing insights and best practices derived from the problem-solving process across the organization.

Key Activities for Taking Preventive Measures

• Review of Related Processes and Systems : Examine other processes and systems that could be affected by the same or similar root causes. This broad review helps identify areas where preventive measures can be applied more widely.
• Modification of Standards and Procedures : Update existing standards, procedures, and documentation to incorporate the learnings and preventive measures identified during the problem-solving process. This may include revising work instructions, quality standards, training materials, and maintenance schedules.

Because of its structured and systematic approach, as well as its emphasis on root cause analysis and continuous improvement, it is an effective method for organisations of all sizes and industries.

The Benefits of 8D Problem Solving:

• Aids in determining the root cause of problems rather than just treating symptoms
• Promotes continuous improvement by preventing recurring problems
• Helps organisations identify and correct problems before they escalate by providing a structured and systematic approach to problem-solving.
• Organizations can use the 8D process to effectively resolve problems and continuously improve their processes for greater efficiency and success.

The 8 Steps of 8D Problem Solving

The 8D process is a cyclical method for problem-solving that is organised and systematic. It consists of eight steps that guide the problem-solving process and aid in the achievement of a successful outcome. The procedure is as follows:

D1 : Form a Team – This step entails assembling a group of people with relevant expertise and experience to work on the problem.

D2 : Describe the Problem – This step entails clearly defining the problem by describing symptoms, and potential consequences, and gathering data to back up the description.

D3 : Interim Containment Actions – In this step, temporary measures are implemented to contain the problem until a permanent solution is found.

D4 : Root Cause Analysis – this step entails determining the root cause of the problem in order to effectively address it.

D5 : Corrective Actions – this step entails creating and implementing a plan of action to address the underlying cause of the problem.

D6 : Corrective Action Implementation – This step entails carrying out the corrective actions.

D7 : Corrective Action Verification – This step involves validating the effectiveness of the corrective actions.

D8 : Long-Term Corrective Actions – this step entails putting in place and monitoring long-term solutions to keep the problem from recurring.

Each step in the 8D process is interconnected, and it is critical to complete each step thoroughly to ensure a successful outcome. Organizations can solve complex problems in a structured and effective manner by following the 8D process.

Best Practices for 8D Problem Solving

Clearly Define the Problem: The first step in solving a problem is clearly defining it. This entails describing the symptoms and potential consequences of the problem, as well as gathering data and information to back up the description.

Involve All Stakeholders: It is critical to include all stakeholders in the problem-solving process to ensure a successful outcome. Individuals or departments with relevant expertise and experience, as well as those affected by the problem, are included.

Focus on Root Causes, not Symptoms: It is critical to focus on finding the root cause of a problem rather than just treating its symptoms in order to effectively solve it. Methods of root cause analysis, such as 5 Whys or Fishbone diagrams, can aid in this process.

Verify Corrective Actions: Once corrective actions have been implemented, it’s important to validate their effectiveness. This includes ensuring that the problem has been fully addressed and that the corrective actions are long-term.

Follow-Up and Monitor Progress: Because the 8D process is a tool for continuous improvement, it’s critical to follow up on the problem-solving process and track progress over time. This includes regular check-ins to ensure that corrective actions are being implemented as intended and to identify any new or recurring problems. Organizations can ensure a successful 8D problem-solving process and continuously improve their processes for greater efficiency and success by adhering to these best practices.

Example of 8D being used to address a customer complaint.

The following is an example of an 8D process used in the manufacturing sector to address a customer complaint:

D1: Create a Team – A cross-functional team of representatives from production, quality control, customer service, and engineering is formed. The team leader is chosen, and the roles and responsibilities of the team members are established.

D2: Describe the Problem – The customer complaint is reviewed and the problem is described as a “defective product delivered to the customer”. The information gathered from the customer and from internal investigations is used to precisely define the problem .

D3: Interim Containment Actions – Interim containment actions are taken to reduce the impact of the problem. To prevent the affected product from being delivered to other customers, the team implements a hold and quarantine procedure.

D4: Root Cause Analysis – The team employs the 5 Whys method to identify the underlying cause of the problem. The root cause is discovered to be a machine malfunction that went unnoticed during the manufacturing process.

D5: Corrective Actions – The team devises a strategy to address the underlying cause of the problem. The plan includes repairing the malfunctioning machine as well as performing regular machine maintenance checks to avoid similar problems in the future.

D6: Carry Out Corrective Actions – The plan of action is carried out, the machine is repaired, and preventive maintenance checks are carried out.

D7: Verify Corrective Actions – The team conducts an internal audit and checks that the machine is functioning properly to ensure that the corrective actions have effectively addressed the root cause of the problem.

D8: Prevent Recurrence – To avoid a recurrence of the problem, the team updates the procedures and processes for machine maintenance checks, as well as providing additional training to production staff. The team also reviews and updates the process on a regular basis to ensure continuous improvement.

The manufacturing company was able to effectively resolve the customer complaint, minimise its impact, and prevent recurrence by following the 8D process.

In Conclusion, 8D Problem Solving is a structured and effective method for dealing with complex issues in any industry. This process brings together a cross-functional team to analyse and solve problems systematically, resulting in long-term solutions and continuous improvement.

Introduction to 8d Problem Solving

The 8D approach to problem solving , also known as the 8D methodology, is a systematic and comprehensive method used to address and resolve complex issues, particularly in manufacturing and other industries.

This 8D troubleshooting methodology involves a structured process designed to identify, correct, and prevent issues, ensuring that similar problems do not occur in the future.

By following the 8D process steps , teams can effectively perform root cause analysis and implement corrective actions.

The 8D structured problem-solving process is highly valued for its ability to provide a clear framework for identifying and eliminating the root cause of a problem, thereby enhancing overall operational efficiency.

Why to Apply 8D Problem Solving Methodology?

The 8D methodology , developed to represent the best practices in problem solving, provides the engineering teams with an effective and efficient team-oriented problem solving skill, a better understanding of Root Cause Analysis (RCA) and how to use basic statistical tools required for problem solving. 8D helps the management understand and resolve problems better, identify necessary systemic changes and inputs for change, and facilitate a more candid and open communication in problem solving discussions.

8D improves the Quality and Reliability of your products, and if performed correctly, prepares the engineering team for future problems.

How to Use Root Cause Analysis to Transform Your Safety Program

8d problem solving approach.

The 8D is a systematic process for the introduction and improvement of quality, and elimination of problems. Here we will show you the step by step approach of the 8D problem solving tools that can make you proficient at identifying causes of problems, defining problems, and errors. Additionally, it helps identify root causes and take actions to solve and prevent identified problems in processes. So, let’s take a peep inside:

D0: Planning and preparing for the 8D

Proper planning and preparation are always a good start before taking any action. So, you need to consider the following before forming a team:

• Problem description
• Timeframe for the resolution
• The number of resources to accomplish this

D1: Team establishment

Create a team with people who varied backgrounds and experiences which will lead to the best quality inputs and a complete solution. For the team to function smoothly, define clear roles, and responsibilities for your people, and have a team leader.

D2: Problem description

The 8D method’s primary focus is to describe the problem appropriately and objectively such that it captures all the vital information. During this analysis, repeated 5W1H (why, what, who, where, when, and how) are required to be asked to develop a clear description.

D3: Problem containment plan

A temporary problem containment plan is sometimes needed to minimize the impact of the problem until you develop permanent solutions. On developing the plan based on the hypothetical cases, the resources for addressing the main problem can be released. At times, new processes may be required to work around the problem until you have a permanent fix.

D4: Root Cause Analysis (RCA)

With the problem temporarily contained, you can now turn to identify all of the root causes of the nonconformance . There are several tools to identify the actual root cause of an issue including the 5W1H to understand the problem in-depth, Fishbone diagrams to visually categorize causes, and Pareto charts to identify the vital causes.

D5: Permanent Corrective Action

Once the root cause of the problem is determined, the team can start brainstorming permanent corrections to identify what the best long-term solution will be. Brainstorming sessions combined with tools such as affinity diagrams help organize ideas based on their relationships and determine the best course of action.

D6: Implement and Validate the Permanent Corrective Action

Once the solution is identified, the management needs to implement and verify the corrective action using the PDCA (plan-do-check-act) approach for small-scale testing before large-scale rollout. Thus, the outcomes and corrective actions are tracked to ensure expected results. To successfully implement a permanent change, a project plan should incorporate:

• Development of the project plan for implementation
• Communicating the plan to all stakeholders
• Validating improvements using measurement

D7: Prevent Recurrence

A complete solution of problems means preventing them from occurring. Besides, preventative measures should also be implemented for corrective actions in the 8D methodology. This requires reviewing management processes, operating procedures, and 8D training manuals to ensure that best practices are followed.

At this stage, organizations should consider actions including updating process audit questions and regularly verifying them based on corrective actions to reduce risk in other processes, presenting poka-yoke or error-proofing devices to big-risk processes, and conducting red rabbit tests to see how long it takes poka-yoke devices to detect defective product.

D8: Verification and Team Celebration

Once the problem is solved, the ultimate step is to congratulate the team. It’s important to recognize their efforts and share their success across the organization because teams require feedback to allow for satisfactory closure. This facilitates motivation and employee engagement while helping you improve quality control, execute process improvements, and aid change management as you grow.

Create a team with people who are having varied backgrounds and experiences which will lead to the best quality inputs and a complete solution. For the team to function smoothly, define clear roles, and responsibilities for your people, and have a team leader.

A complete solution of problems means preventing them from occurring initially. Besides, preventative measures should also be implemented for corrective actions in the 8D methodology. This requires reviewing management processes, operating procedures, and training manuals to ensure that best practices are followed.

8D Root Cause Analysis (RCA) and 8D Corrective Action Process

The 8D Root Cause Analysis, as well as the 8D Corrective Action process, is a widely systematic approach in quality management , especially concerning 8D in quality control. This method includes eight comprehensive steps that are devised to problem solving by dealing with root causes of the problems comprehensively. The steps of the 8D process start with the formation of a team, a clear definition of the problem, and move on to interim containment actions. This is then followed by detailed root-cause analysis using the 8D RCA process, development and verification of permanent corrective actions, implementation, and recurrence preventing efforts. Encouraging details in the analysis: the 8D methodology steps encompass collaborative efforts and documentation that ensure durable solutions and continuous improvement in organizational processes. Root Cause Analysis (RCA) is embedded within the 8D process and includes the following steps and techniques:

Problem Symptom is measured and transformed to “Object and Defect”

Problem Symptom is reformed to Problem Statement using the 5W1H process

Potential Causes are gathered using the tools like Fishbone or Affinity Diagram

Problem Statement should fit using both the “is” and the “isn’t” sections of the question

Root Cause concepts are developed from remaining possible causes on the tool and related changes from is/is not

Compare theories with recent data and develop experiments for Root Cause Verification

Test and confirm the Root Causes

Integration with statistical tools and data analysis in every step of 8D analysis is sure to make the most accurate identification of the root cause.

This approach would ensure that cross-functional teams' participation would not only be present in the brainstorming sessions but also in the 8D problem solving process at the problem solving stage.

Training in 8D Methodology

8D training is an inevitable imperative that makes its deployment in organizations effective. The 8D methodology provides all the necessary details that the teams could apply to the skills and knowledge required at every step in 8D of quality control . Training the workforce on 8D methodology will make them able to apply these aspects when dealing with real-world problems, which will better off the quality and efficiency of the entire organization. It ensures that all these measures and strategies have been inducted to make sure that 8D problem solving approaches are not just tools for problem solution but have been inducted to lay down the base for sustainable quality improvement and prevention practices in the organizational processes.

8D Problem Solving Report

8D problem solving reports and templates are useful tools to initiate a problem solving process. These reports are used to explain what 8D is and including information about each step so that one will know what needs to be done by attempting this to solve problems. Keeping these reports easily available can avoid repeating work on the same problems over and over again.

8D reports must be detailed and incorporate information at every step within the 8D process. Those who are working on the problem should provide sufficient information when completing a report so that someone who was not on the current 8D team can pull it out and understand what the problem was and what solutions were implemented.

8D Problem Solving: A Step-by-Step Guide

8D problem solving is an excellent framework for addressing complicated manufacturing problems and beyond. I’ve watched it turn around many a troubled production line. It’s a systematic way to analyze a problem step by step and ensure you don’t miss anything. You’ll learn to build the right team, determine the root causes, and fix the problems for good. So, here are the specifics of the framework.

What is 8D Problem Solving?

Ford Motor Company developed the 8D model in the 1980s, originally called Team Oriented Problem Solving (TOPS). However, the company borrowed the structure from earlier problem-solving processes implemented by the U.S. government and military.

At its essence, 8D adheres to these core principles:

• Team-oriented problem solving
• Data-driven decision making
• Root Cause Analysis
• Permanent corrective action
• Prevent recurrence

You’ll see 8D utilized throughout various industries, including:

• Automotive manufacturing
• Electronics
• Food manufacturing

Implementing 8D delivers numerous benefits. You’ll observe higher product quality, lower costs, and improved customer satisfaction. Plus, it instills a culture of continuous improvement in your company.

In my consulting experience, companies that embrace 8D experience fewer recurring problems. In other words, you’re not just solving problems – you’re also stopping them from coming back.

The 9 Steps of 8D Problem Solving

Originally, the process consisted of 8 steps. However, a planning step (D0) was later added to the beginning of the process, making it a 9-step approach. Let’s discuss each step:

• D0: Plan and Prepare
• D1: Build the Team
• D2: Define the Problem
• D3: Stop the Current Problem from Getting Worse
• D4: Find and Verify the Root Cause
• D5: Implement Permanent Corrective Actions
• D6: Implement and Validate the Solution
• D7: Prevent Problem from Recurring
• D8: Congratulate the Team and Turn the Game off

Each step is essential to solving the problem at hand. You cannot skip any steps, nor should you rush through them. Companies will always come up with a reason to shorten the process—but it never fails to result in an incomplete solution or the problem arising again.

The D0 step, in particular, is of utmost importance, as executing the step ensures you have the resources, data and political support to solve the problem as you now intend to.

When I do consulting work, I preach this methodical approach to problem solving. Using this structured approach will make you a more thorough and effective problem solver.

Forming the 8D Team (D1)

Building the right team is essential to effective 8D problem solving. You need a combination of skills, expertise, and viewpoints, as 8D problem solving deals with complex issues.

In 8D problem solving, the core team is usually 3 people for data analysis and a larger team of subject matter experts when you need to brainstorm or experiment. This two-tier team structure enables effective data analysis and broader brainstorming or experimentation.

When selecting your team, consider the following:

• Relevant technical expertise
• Problem-solving skills
• Communication skills
• Availability to participate throughout the process

It’s important to have clear team members and roles defined. You should have:

• A team leader to guide the process
• A recorder to document any findings and actions
• Subject matter experts

Diverse cross-functional teamwork is essential. If teams are too homogeneous, I’ve noticed that they struggle to find the right solution. You need different insights to collectively challenge assumptions and recognize innovative solutions.

Team size is another consideration. I’ve found that a core team of 3 to 5 people works well. If you have too many people, the process becomes cumbersome and slow.

Describing the Problem (D2)

To define the problem accurately, look at the following:

• Quantitative data (measurements, frequencies, costs)
• Qualitative data (customer complaints, any anecdotal information)
• The “5 W’s and 1 H” (Who, What, When, Where, Why, How)
• A problem statement that is specific, measurable and ideally objective

If the problem could be interpreted as a vague or subjective statement, it isn’t specific enough. For example, “Quality is bad” isn’t specific enough. “We’re finding that 10% of all weld joints are failing inspection due to surface defects” is specific enough.

This is where the actual data comes into play. Look at the data both quantitatively and qualitatively. What are you seeing that tells you you have this problem? Then, what are those numbers saying with respect to patterns, trends or anomalies? This will help you determine the real problem you’re dealing with.

Remember: A problem well-stated is a problem half-solved. If you have to go back and redefine it later, you’ll waste a lot of time and energy on the later steps of the 8D process.

Implementing Interim Containment Actions (D3)

Containment actions are short-term steps that prevent the customer from feeling the problem’s impact. These aren’t true solutions, but they allow you time to identify and implement permanent solutions.

Common types of interim containment actions include:

• Increased inspection
• Sorting suspect product
• Process changes
• Customer communication
• Temporary design changes

The key with these actions is speed. You should do everything in your power to stop the customer from feeling the pain. Many companies get stuck at this phase, worrying about the cost or admitting there’s a problem. This short-term thinking always results in bigger headaches later.

Assess whether your containment actions are effective. Are they truly stopping the problem from reaching the customer? If not, how can you adjust or add another containment action?

Thoroughly document all of your containment actions. You’ll use this information later to develop permanent solutions and ensure the problem doesn’t happen again.

Identifying and Verifying Root Causes (D4)

Root cause analysis is the process of delving deep to discover why a problem truly occurred. It’s not about who is to blame – it’s about understanding why the problem occurred in the first place.

The method uses a variety of problem-solving tools, including:

• Fishbone diagrams
• Pareto charts
• Failure Mode and Effects Analysis (FMEA)
• Statistical process control

Personally, I’ve found the 5 Whys to be particularly helpful. This involves asking “why” multiple times to get to the root cause of a problem. It’s a very basic strategy, but it’s surprisingly effective.

A common mistake to avoid is confusing symptoms with causes. For example, “operator error” is almost never the root cause of a problem. You need to dig deeper to figure out why the operator made an error. Was it due to a lack of training? Poorly written instructions? Bad equipment design?

Once you have a list of potential causes, verify them through data analysis. Can you recreate the problem using the suspected cause? Can you prevent the problem by controlling the cause?

This step can be tedious and requires patience. Don’t accept the first explanation you come across. Keep asking “why” until you’re confident you’ve found the true root cause.

Developing Permanent Corrective Actions (D5)

Now that you’ve identified the root cause, it’s time to brainstorm permanent solutions. This is the fun part where you get to be creative and innovative.

The most effective corrective actions will:

• Address the root cause of the problem.
• Be possible to execute.
• Not create other problems.
• Prevent the issue from happening again.

Gather your team and brainstorm potential solutions. It’s important to encourage creativity here. Some of the best solutions I’ve seen have come from someone who wasn’t directly involved in the problem.

Evaluate each potential solution based on your criteria. Also, evaluate the long-term impact of the solution. It’s easy to fall into the trap of implementing a quick fix, so ask yourself, “Will this solution truly prevent the issue from happening again?”

Include the people who will execute the solution in the brainstorm. This might be the line operator, an engineer, a quality person, etc. The people closest to the problem will often have the best solutions.

Remember, the objective is to solve the problem forever. Don’t allow the team to implement a solution that will only fix the problem for now.

Implementing and Validating Solutions (D6)

The 8D framework places a strong emphasis on using data and quantitative analysis to verify that your selected corrective actions will actually fix the problem. To do this, set up measurements and define what success looks like before implementing your solutions.

When you implement your solutions:

• Create a detailed plan of attack.
• Assign each step to an owner along with a due date.
• Communicate changes to everyone who needs to know.
• Train people or provide resources so they can execute your solution.
• Monitor the implementation process closely.

After implementing your solutions, verify that they actually worked. Are you seeing the improvements you expected? If not, you may need to revisit your solution.

Thoroughly document all of the changes you made. This documentation is essential for creating standard operating procedures, training new hires, and making sure the issue never happens again.

In my consulting content, I constantly reinforce the importance of verifying that your solutions worked. Don’t just assume they did – show it with data.

Preventing Problem Recurrence (D7)

Prevention is about implementing systemic changes so the issue doesn’t happen again. It’s a step many people forget, but it’s arguably the most important.

Here are a few prevention strategies:

• Update procedures and standards
• Add error proofing
• Enhance training
• Improve communication
• Change design or manufacturing

Think conceptually about the issue. What other processes or products might have the same problem? If so, make sure to prevent it there as well.

Training is often the solution. Make sure all relevant employees understand the issue, why it happened, and how to prevent it from happening in the future.

Set up continuous improvement processes. Preventative checks, audits, process reviews, and feedback loops help you catch issues before they become huge problems.

I’ve also witnessed companies change their entire business with effective prevention. It’s not just about fixing issues – it’s building a quality and continuous improvement culture.

Recognizing the Team and Closing the Process (D8)

The eighth and final step of the 8D methodology is often neglected, yet it is key to long-term success. Recognizing the team’s efforts and formally closing the process yields closure and encourages future engagement.

When recognizing the team:

• Recognize individual team members
• Celebrate the team’s success and learnings
• Explain the impact of their work
• Contemplate offering formal recognition or rewards

Capture lessons learned. What worked well? What didn’t? This learning is invaluable for future problems that arise.

Communicate success stories to your entire organization. This step generates additional buy-in for continuous improvement and motivates other teams.

Formally close the 8D process. This action signifies the end of immediate problem solving and the beginning of ongoing monitoring and improvement.

In my experience, teams that feel recognized are more engaged and hungry for the next problem to solve. Once you play this last step, you’ll realize the ROI of 8D again and again.

Tools and Techniques for 8D Problem Solving

Effective 8D problem solving requires various tools and techniques. The 8D process itself is a methodology, so training in the 8D process and various data analysis tools is necessary to effectively execute the process.

Common 8D tools include:

• 5 Why analysis
• Scatter plots
• Control charts

Using the right tool for each step is critical. For example, you might use a Pareto chart to prioritize issues in the problem description step and a fishbone diagram to identify potential root causes.

The key to making these tools work in the 8D process is to ensure the 8D process integrates them. They’re not tools sitting in isolation from one another; they all fit together to create a comprehensive problem-solving strategy.

Training is also key to effectively using the tools. I’ve seen many teams struggle with the 8D process simply because they didn’t have the data analysis tools down pat. So, invest in training for your team members to make the problem solving process itself more effective.

8D Reporting and Documentation

An 8D report is how suppliers communicate with customers about what they have done to address a complaint. Therefore, it’s an essential communication piece in the 8D process.

The key to a great 8D report is:

• • A clear description of the problem
• • Details of containment actions
• • Results of the root cause analysis
• • The corrective actions taken
• • Evidence that corrective actions worked
• • Preventative measures

Best practices for writing the report:

• Use clear, concise language.
• Use data to justify your conclusions.
• Use visuals when they clarify the point.
• Keep the report updated as you move through the 8D process.

Why document each step? It creates a paper trail of your problem-solving process, supports decision making, and allows other people in your company to learn from what you’ve already tried.

Use 8D reports to update stakeholders on your progress (both during and at the end of the 8D process). Keeping stakeholders informed aligns everyone involved in solving a problem. And a rule I live by is that the more aligned all stakeholders are, the more trust and support you’ll have in your problem-solving process.

Challenges and Best Practices in 8D Implementation

While implementing 8D is complex, the benefits justify the investment. Common challenges include change resistance, resource constraints, and difficulty determining the true root cause.

• To mitigate these challenges:
• Get management buy-in
• Offer proper training
• Allow time to conduct a thorough analysis
• Create a blameless culture that focuses on making things better
• Tips to ensure successful implementation of 8D:
• Start with small pilot projects to gain confidence
• Use a skilled facilitator to ensure early success
• Standardize your 8D process and tools
• Continuously assess and improve your 8D system

Measuring the effectiveness of your 8D process is essential. Use KPIs such as problem recurrence, time to solve, and customer satisfaction.

In consulting, I’ve witnessed companies completely change their ability to solve problems accurately by implementing a robust 8D process. It’s not easy, but the quality improvements and cost savings are significant.

Parting Thoughts

The 8D problem solving process is a great framework for addressing complicated problems. It offers a systematic way to discover root causes and resolve them with permanent solutions. In my experience, the key to success is ensuring proper execution through commitment, training, and cross-functional teamwork.

You’ll encounter challenges, but the benefits of the 8D process justify the investment. By using the 9 step methodology and selecting the right tools, you can instill a culture of continuous improvement within your company. Just keep in mind that effective problem solving is a continuous journey. Continue to optimize your strategy, and you’ll notice a significant increase in both efficiency and quality.

8D (Eight Disciplines) – The problem Solving tool

In this modern era, to sustain products in the market needs to use advanced manufacturing processes. Modern machinery and cost effective processes for produce quality products with low cost. but as you all know that. It’s difficult to constant manufacturing processes and sustain product quality. Because it is natural that, during the working time unexpected problems can be occurred and that kind of problems must be resolved in respective manner. Some organizations are used outmoded technique that solve the issues on temporary basis. As well those problems can be possible reoccur in processes in future.

So, needs to efficient system that eliminate the possibility of reoccur issues as well as smooth the manufacturing processes. Fortunately, we have some problem solving tools can solve the issue permanently. 8D (Eight disciplines) is one of the popular problem solving tool that in now days, organizations are adopting pleasurably. OK, so let’s see how to implement 8D in organization.

What is 8D (Eight Disciplines)?

“8D (Eight Disciplines) is problem solving tool / methodology used for correctly identified the cause of the problem, fixed and dissipate possibility of recurrence of quality problems.”

8D model is systematic approach popularly used in responding to manufacturing issues. Generally, quality team conduct eight disciplines processes for identify root causes of problem and eliminate it by appropriate actions. The 8D (Eight Discipline) model is correctly identify the cause of the problem. And apply such actions to prevent recurrence of the problem. 8D is perform as preventive and corrective action system by implement step by step process to identify potential and actual problems in processes.

Benefits of 8D (Eight Disciplines)

• The 8D method is very easy for implement in workplace as well as logical method that clearly indicate required steps of problem solution.
• The method is very popular in automotive industry, mean your customer may ask for 8D report for its own application implementation. Because it is reliable and well know problem solving tool for automotive industry.
• An excellent way of reporting non conformance to suppliers and their corrective actions.
• 8D helps to eliminate complicated issues at appropriate locations where defined the causes of the problem incorrect, lack of consequences in implementation and same problem appear again.
• The team approach works best when the problem, and its associated information is labyrinthine. Because 8D is designed and capable for special cause of problems identification and elimination.

8D (Eight Disciplines) Process Chart: Table

8d (eight disciplines) methodology.

• D1: Team Establishment
• D2: Problem Description
• D3: Containment Action
• D4: Root cause
• D5: Corrective Action
• D6: Implement and validation corrective actions
• D7: Prevent recurrence
• D8: Verify and congratulate team

The 8D (eight Disciplines) is a process for systematic introduction of quality perfection, improvement and elimination of problems. Here in this article I will show you step by step approach and using several examples of the problem solving tools . When we involve in 8D methodology and its processes using a structured method, we become very effective at identifying cause of problems, defining problems and mistakes. As well as easily establish root causes and taking actions that solve and prevent problem identifying in processes.

So, let’s see 8D (Eight Disciplines) in deep:

As you well know, whenever any problem occurring in the manufacturing processes before you must see some warning sign that indicate the problem. Which is being experience in terms of an undesirable results and can be describe using data to identify the variation as expected and actual results.

Actually, this is the preparation stage that require to be complete before starting the eight disciplines processes in organization. Generally, peoples asking what type of preparation required before 8D process? –

A deep analysis and empathetic of the issues and problems, previous experience with same issues or related issues are necessary to determine. If the eight disciplines (8D) is the correct method to be used for solving the issues.

You have to ask the questions as below as recognizing the problem:

• Describe it is new problem in organization / division? If same problem, occur previously at where? If it is new how long from it were being in process. Or it is unknown cause?
• Has it occurred before? where? and what solutions / actions are applied at on it? What is the history of this problem?
• Why it’s happened again? is there proper solutions are not applied? what causes behind it is occur again?
• What problem solving method was used? It was joint method for one or more problem? if it is separately performed what was defects remained in method?
• To consider warning sign of problems is it really looks very complex to one person cannot resolve the problem?
• To consider above points, does the problem warrant required an eight Disciplines (8D) method? if yes, why and proceed it.

The 8D (eight disciplines) process is a team based problem solving methodology. Hence the team members must be involve for identify, action plan and eliminate issues of appropriate problem. A deeper understanding of the problem & its previous records are required to ensure if the 8D solved issues for raise issue.

D1 »  Team Establishment

The team establishment is first step of the 8D (Eight Disciplines) approach. This discipline is significant stage as the eight disciplines is based on the substance of team cooperation. Establishment group of peoples called CFT (Cross Functional Team) where must each one from different department is selected by management, with the production process knowledge, product knowledge, and skill in the required technical disciplines to solve the problem and implement corrective actions.

Why team approach is important?

• CFT (Cross Functional team) build by group of peoples from different department and expertise. So any technical issues can be possible to identify, fix and eliminate problem through it.
• A Cross functional team can perform more effectively than individuals trying to solve problems.
• Cross functional team may have adequate capability to introduce proper solution of the problem.
• A group of people can discuss, focus on negative effects of actions, and can think creatively.
• Brainstorming as a group can stimulate ideas giving the team a better perspective of the problem.

A Cross functional team for eight disciplines consists of more than two people who are closely concern to the problem. Generally, involves peoples form different departments in the organization coming together to solve a problem. The skills that the team members require for this discipline to ensure the proper solution are:

• (A). Team member must knowledge of product / part / item (manufacturing processes, assembly etc.)
• (B). Team member must know the process where the problem has showed itself.
• (C). Team member must have knowledge of the customer application, technical use and end application requirements.
• (D). Team member must have skill about decision making, communication skill , and analysis of the processes and data related to manufacturing processes.

How to define team role & responsibility?

Usually, every team must have leader, here the same team leader has an important role to establish procedures and implement actions accordingly. The team leader must prepare a list defining the team structure as eight disciplines concern. the list is also important to establish role & responsibility in 8D processes. Every team member has its own importance in 8D methodology. Because every single member comes with different expertise. Hence to solve problem multifunction conception and views helpful for appropriate issues.

The role and responsibilities of the individual team member must have allocate by the team and will involve some of the points are:

Data collection and analysis, experimentation, decision making processes, modelling managing resources, planning and implementation of action plans, action plan verification and validation, communications etc.

The common processes and requirements for the 8D processes needed to contribute to the problem solving effort.

D2 »  Problem Description

Problem description is a second stage designate for deep into the problem & getting a more complete information and sophisticated understanding of the problem. The problem description indicates, problem clearly identify and the eight discipline problem solving planner activities to take as much actual information as possible. Which organizes the first analysis perform in the problem solving process. You have to describe problem accurately in this stage, clear designed information is foundation to further steps of analysis.

The process of this discipline as below:

Describe The Problem Process Flow: Table

A problem description is the results of a practice that uses the is / is not method to magnify the problem statement. The location and nature of the problem have to be describe along with its impacts. Another very important analyzing results of information. To ensure that the problem involves is recurrent or whether it could occur on particular process or product.

See table below help for better understanding:

Describe the problem with Is / Is Not Method: Table

When the describing the problem with 5W + 2H (Who, What, Why, Where, When, how, how many / much) method should be use. Where you get the answered thoroughly and systematically by the questions.

See picture below for problem analysis worksheet:

Remember that, you have to specified problem statement been defined, and you have get to know for certain why that is occurring. So Is / Is not analysis must been perform for it. You have to also verify that the similar parts / components displayed the same problem? current process flow identified? does this process flow represent a change.

Once you get the answer you can collect the data and analyze it. The information you collected are evaluated for potential root causes, and identify physical evidence of the problem. The problem description been reviewed for completeness with 8D (Eight disciplines) customer and affected parties, and document the activities.

D3 »  Containment Action

This is the stage where are taken correct containment action to prevent escalation of the problem. Or at the worst delivering non-conforming product to the customer. You have to describe the containment action plan to put in place in order to eliminate the effects of the problem. In this stage, immediate correction action should be carrying out in the shortest time possible. The main objective of the implement interim actions / containment actions to isolate issues from parties while a permanent solution is being develop and implement.

Why containment action required?

• When the cross functional team working on identification of the root causes of problem , collecting information and other related processes might possible some defective product produced by manufacturing in tenure. So, it is extremely important containment actions on this condition at appropriate locations.
• To ensure the customer has minimal or no impact felt as a results of the problem identified, as well prevent these defective products from getting the customer.
• In case of any defective lot / product reached to customer, it may not comply requirements to end application, hence customer will claim and complaints as results customer dissatisfaction.
• Due to immediate actions, the similar products and processes must be verified and ensure the risk levels are minimum or not evident.

Through PDCA Cycle

Plan »  Prepare the most effective containment action plan and implementation including verifying the containment action effectiveness and concerned activities such as work instructions , resources and equipment available.

Do »  The plan must execute as containment action plan prepared, and ensure that the actions should be clearly communicated at processes and management levels.

Check » It is cross function team responsibility that every containment actions prepared during the planning section must be implemented exactly accordingly and ensure that it may continue to be effective. One of the important activity of this section is to verify and ensure that. The activities must not any other side effects raise as a result of the containment actions.

Act » Take the actions to ensure containment action are effective and sustained with all manufacturing and supporting processes. Take the questioners and get the feedback from internal and external customers to implement and make sure is there further containment actions or correction required to rectify other issues.

8D – Containment actions checklist

8D containment action points:

D4 »  root cause.

On this stage in Eight disciplines (8D) problem solving process, needs to establish and describing the root causes of a problem is the core of this disciplines. And you will have appraise the team structure and configuration to ensure that all the right skills and experience is available for the upcoming phases or processes in the problem solving effort.

Elimination of the problem should be detecting the real cause of the problem. The objective of the explain and verify root causes is to identify all significant causes which could clarify why this problem happens. An eliminate and confirm the root cause by examine each significant cause against the describe problem and results of tested data.

For define and verify root causes you have to step out as below:

• Establish a process flow and Cause and Effect Diagram to include all the sources of variations.
• Develop a stratification cause and effect diagram, but remember that, the cause and effect diagrams used input from all team members, lack of the information of remains any points or data left, you will not get real cause.
• Establish comparative analysis, by determine critical differences between problem location and non-problem locations.
• You can also use time line analysis. Graphical / visual charts give you better understanding in most cases.
• Index the potential causes of problems by use both the process flow and cause and effect diagram.
• By using the both the tool, you can analyze the potential cause for the most likely cause.
• Determine slot of data, identify the potential cause as a root cause.
• Collect and analyze the appropriate information to identify the potential cause as a root cause.
• Specify causes that permitted the apparent warning sign to occur, are the root causes and often repressed deep in the processes. You can use the tools to help in the whole processes that is problem solving techniques are : (1)  Pareto charts  (2) 5 Whys analysis (3) Statistical analysis (4)  Flow charts  (5) Fishbone diagram (6) GR & R study (7)  FMEA  (8) Frequent audits (9) Fault tree Analysis (10) Brainstorming etc..

The time line is one of the important and useful tool that manage the records at time line of all events in and around the problem.

A company making steel tubes is experiencing a pits on tubes problem identified.

The significant processes / event are recorded on a time line are:

The time line helps to draw processes and events on time. Though it you can get the answer when actually the problem was first seen at which location. Now you can filter out possible causal theories later in the process by identifying what could possibly have caused the problem and what could not have caused the problem.

There are more three important stages you have to concentrate are:

(1) Develop possible causal theories (2) Establish possible root causes (3) Verify possible root causes and define and verify escape point.

You must do deeply thought about the possible causes and documents on separate media. For each of the cause you have to prepare a proper theory that describe how that the possible cause would result in the problem being experienced. You have to do write note of each ideas for develop causal theory for possible root causes.

Ask the simple question to each causal points that answered in “IS” / “IS NOT”. Does this explain the reason why the problem exists on the “IS” and not on the “IS NOT”. For separately of the possible root causes, there now requirements to be useful action to validate the possible root cause. This should be carried out in practical terms wherever possible.

D5 »  Corrective Action

On the fifth stage of eight disciplines, the cross functional team must determine which corrective actions should be establishing and implement in the short period of time to ensure that the processes and product quality maintained and controlled. The corrective actions must be requirements that satisfy both the parties internal and external customers. Once the root causes are known, team concentrate on the permanent solutions, by systematic approach is needed to use the root cause analysis to establish actions for proper solution. The points that you need to focused on:

• Empathetic and defining the problem, the eight disciplines (8D) team must be able to defining the problems and implement the solution practically.
• Enclosing the effects of the problem, please note that implementation and using the program for solution must be cost effective.
• Identifying and verifying the root cause of the problem.
• Need to permanently solve the problem, and the solution must be feasible.
• Confirm the potential solutions through testing programs, and remember that the implementation program should not fail during the implement in production so, it is important the solution is a test and essential characteristic such as mistake proof and affordable.
• Verify that the solution eliminates the problem and its effects;

In fifth stage of eight disciplines, the team can introduce the additional control in the processes, and ensure that the solution is properly validated that during the implementation in running production it will not raise any unwanted issues, so trail on the small quantities first to verify the solution is effective is necessary. To ensure that the permanent corrective actions need to establish proper process flow for it, see the example process flow:

Verify Corrective Actions Process Flow: Table

Verify the corrective actions.

It is extremely important that all the established actions and implementation plans for fix the issues must be performed to not leading any further problems. So, cross functional team must well aware of this kind of technicality and must should try out the implementation program with small part of production or small quantities first to verify its effectiveness.

Corrective actions test with pre-production with small quantity can confirm that the identified corrective actions will resolve the problem of the customer, and ensure that will do not any undesirable side effects.

Check points

Somethings that still need to confirm and ensure that corrective action is will properly works at real production. Some points that help you to re-verify the condition such as:

• (1) List and measure all of the indicators related to the program.
• (2) identify which of the indicators are most direct relation to the program.
• (3) Determine intervals to measure the problem.
• (4) identify what cross fictional team prioritized the customer / end user evaluation after the implementation.
• (5) confirm the scientific methods used to verify effectiveness etc.

D6 »  Implement and validation corrective actions

On the stage of validation corrective actions, the cross functional team consists of measuring the long term effectiveness of the corrective actions. The purpose of verification of the corrective action is ensure that the actions are implemented are efficient and these are eliminated permanently through effective controls and activities that are embedded in the tasks of the process. Some indicators that you can ensure that the corrective actions are properly works:

• Test and control results display improvement
• Less Rejection or reject ppm (%) in process.
• Measurements such as dimension, units’ appearance are correct according to tolerance and specifications.
• Controls on incoming raw materials for quality improvement.
• Increased satisfaction ratio and feedbacks from customers.

The statistical tools such as process capability, histograms, control charts etc. can used to measured and verify the effectiveness of the implemented corrective actions. The cross functional team must have informed to customer about the results achieved, if the process capability submitted with the requirements the customer validates the corrective measures functional. The 8D team confirms whether the capability complies with internal manufacturing requirements, if the process capability complied the team validates the corrective action.

Checkpoints:

You can use PDCA cycle for implement this stage in manufacturing processes. The implementation of the permanent corrective action conduct to implement to verify the plan for validation of the corrective action. You can plan to withdraw containment (immediate) action as part of implementation of the corrective actions.

There is also important that each resources used in processes must be properly planned as well as all documentation, process instructions and communication implementation for corrective actions. Check that the corrective actions have been implemented and integrated into the appropriate tasks and manufacturing processes. Take the actions on any variation from the plan or expected results.

D7 »  Prevent recurrence

On this stage, the cross functional team have to determine what action should be taken to prevent recurrence of the problem. You have to amend those operating systems, regular practices, management system as well as procedures to prevent recurrence of this problem and all similar issues. Because preventing recurrence is a one of the important task of problem’s solution. The general process flow of the prevent recurrent is:

• Input implemented corrective actions and validation
• Review the history / previous record of the problem.
• Analyze how this problem occurred and escaped.
• Identify affected parties and opportunities for similar problems to occur and escape
• Identify the system’s policies, practices and procedures that allowed this problem to occur and escape to the customer.
• Revise the process flow of the management or operating system.
• Analyze how similar problems could be addressed.
• Develop plans to coordinate necessary actions. And verify prevent actions.
• Develop systematic prevent recommendations to process owner.
• Identify and choose prevent actions. And implement preventive actions.
• Make the system changes to prevent recurrence.
• Verify the preventive actions are effectives? If yes, Standardize the new practices.
• Notify all personnel of the resolution actions by using failure mode effects analysis.

In this stage of the 8D (eight disciplines) cross functional team analyses whether the corrective action implemented would prevent or improve the quality of similar products and processes. To ensure the prevent recurrent of the problem, you should verify results of their actions and must validate that the results is on target. To verify the actions, you must check out below points:

D8 »  Verify and congratulate team

The last stage of the 8D (Eight Disciplines) Is verification of the introduced actions in previous stages are effective. It is highly recommended that verification be made by comparing the measures of the problem with outcomes from upcoming actions of material or outcomes from rejecting of next lot. Once cross functional team has complete implementation all previous stages and ensure that the actions taken in previous stages are works. All team member deserve to be congratulate as well to know that their efforts are appreciate and that the organization knows about their accomplishments.

The cross functional team must have skills and experience to be able to make progress toward as satisfactory problem resolution, and skills and experiences are base reasons for individual selection. Different skills and experiences will support to be drafted in at various stages throughout the process to get the deep understanding about the symptom of problem, root causes and resolution.

The 8D report

From beginning to end of all 8D (Eight Disciplines) processes, the single document calls 8D report is essential part once complete. Team assume that all things are complete and fix as appropriate actions for appropriate issues. This report serves as a communication tool displaying overall process of the 8D (Eight Disciplines) processes along with actions taken. So, let’s see example format of 8D report:

Conclusion:

When the problem has been resolve. The cross functional team should release a final document with stage wise brief description about its experiences. The 8D report give quick and better explanation of how the whole process had handling by team and also 8D serves report as a communication tool displaying overall progress of process.

We can assume that, the successful corrective actions have eliminated repetition of problems and prevention of similar issues. Further, team must ensure that corrective actions will be assess on their ability to help avoiding future problems. If we do not distinguish between major and minor problems, any issue will hold the delivery of customer and that is the reason we must have to categorize by identify systematic issues to eliminate appropriate problems.

8 Disciplines (8D) Problem Solving Explained

It goes back a long way and was even used during World War II by the US government, and was called Military Standard 1520. It was later popularized by Ford’s use in “Team Oriented Problem Solving (TOPS)” where it was initially adopted as a method of documenting problem solving efforts. The template later evolved and is still being used by Ford.

What are the main strengths of an 8D Problem Solving method over a more basic problem-solving method?

• The 8D problem-solving board facilitates cross functional team collaboration for effective problem solving.
• Containment actions act as a “first aid” plaster that protects the organization from the problem until the root causes are defined and permanent corrective actions are implemented.
• Future preventive actions are proactive and oriented towards a forward-looking approach which spots potential problems before they happen. This is a great mindset to encourage in a company culture.

The purpose of 8D problem solving is to systematically identify, analyze, and resolve complex issues in a structured manner. It promotes a team-based approach to address root causes, prevent recurrence, and improve processes. Employing the eight disciplined steps enhances problem-solving skills, fosters continuous improvement, and ensures customer satisfaction.

What are the 8 Disciplines?

Step 1: FORM A TEAM Based on the problem at hand, the team Leader will establish a team. This should be formed with employees from different departments to allow additional perspectives on a problem.

Step 2: PROBLEM DEFINITION The 8D method’s initial focus is to properly describe and to understand the severity and occurrence of the problem. This sets the scene for identifying the importance of risks or issues involved with the problem.

Step 3: CONTAINMENT Once the team identifies the problem, the immediate next action is to provide a temporary solution to the problem. This should be quick and easy to implement. This is a plaster solution to contain the problem. The temporary action implemented is removed once the permanent corrective action is applied (See step 6).

Step 4a: ISHIKAWA/ FISHBONE DIAGRAM Root cause analysis is the core and most important section of 8D. The Ishikawa diagram is a fantastic tool for identifying multiple root causes of a problem. The root causes are categorized into six categories (Man, Measurement, Machine, Method, Material, Nature) which helps you to not miss any possible root causes of a problem. This structure helps team members think in a very systematic way.

Step 4b: 5 WHYS ANALYSIS Once identified, there is a need to delve deeper to get to the roots of the problem. If the roots are not removed, the weeds will re-grow.

The 5-whys technique is one of the most preferred approaches to minimize or possibly eliminate issues. By repeatedly asking the question “Why?” Each time a further Why? is asked (up to a maximum of 5x), you can distinguish the symptoms from the causes of a problem.

Effective use of the 5-whys analysis technique will determine the root cause of all non-conformances and subsequently lead to the development of effective, long-term corrective and preventive actions.

Step 5: IDENTIFICATION OF PERMANENT CORRECTIVE ACTIONS Once the team establishes the root causes, the next step is to identify permanent corrective actions. Corrective actions ensure improvement and elimination of causes and prevent the same kind of problem happening again.

Step 6: IMPLEMENTATION OF PERMANENT CORRECTIVE ACTIONS To successfully implement a permanent solution to the problem, proper and systematic planning is necessary. The task is defined, the owner and due date are assigned and, most importantly, the status is monitored to ensure successful implementation. As always, auditing and monitoring is vital to a lasting & successful outcome.

Step 7: IDENTIFICATION AND IMPLEMENTATION OF FUTURE PREVENTIVE ACTIONS In line with the continuous improvement principle of lean, all firms should not just stop with taking corrective action but should strive to adopt a proactive approach. Unlike a corrective action, which fixes the root cause of a current issue, future preventive actions try to address problems before they happen.

Step 8: RECOGNITION Share and praise the team successes. It is a great motivator!

What are the benefits of 8D problem solving?

8D problem solving is a powerful tool that encourages collaborative team-based problem solving. This approach harnesses the collective intelligence and skills of a group to address issues efficiently and creatively. The diverse perspectives and expertise of the team leads to innovative solutions that individuals might not achieve alone. This tool not only helps implement corrective actions for the current issues, but it also helps teams anticipate potential challenges and develop measures to address them before they escalate. 8D provides a well-rounded problem-solving strategy, enhances productivity, and fosters a culture of continuous improvement.
