“People ask me questions Lost in confusion Well, I tell them there's no problem Only solutions” —John Lennon, “Watching the Wheels”

Despite John Lennon’s lyrics, nobody is free from problems, and that’s especially true in business. Chances are that you encounter some kind of problem at work nearly every day, and maybe you’ve had to “put out a fire” before lunchtime once or twice in your career.

But perhaps what Lennon’s saying is that, no matter what comes our way, we can find solutions. How do you approach problems? Do you have a process in place to ensure that you and your co-workers come to the right solution?

In this article, we will give you some tips on how to find solutions visually through a problem-solving flowchart and other methods.

What is visual problem-solving?

If you are a literal thinker, you may think that visual problem-solving is something that your ophthalmologist does when your vision is blurry. For the rest of us, visual problem-solving involves executing the following steps in a visual way:

• Define the problem.
• Brainstorm solutions.
• Pick a solution.
• Implement solutions.
• Review the results.

How to make your problem-solving process more visual

Words pack a lot of power and are very important to how we communicate on a daily basis. Using words alone, you can brainstorm, organize data, identify problems, and come up with possible solutions. The way you write your ideas may make sense to you, but it may not be as easy for other team members to follow.

When you use flowcharts, diagrams, mind maps, and other visuals, the information is easier to digest. Your eyes dart around the page quickly gathering information, more fully engaging your brain to find patterns and make sense of the data.

Identify the problem with mind maps

So you know there is a problem that needs to be solved. Do you know what that problem is? Is there only one problem? Is the problem sum total of a bunch of smaller problems?

You need to ask these kinds of questions to be sure that you are working on the root of the issue. You don’t want to spend too much time and energy solving the wrong problem.

To help you identify the problem, use a mind map. Mind maps can help you visually brainstorm and collect ideas without a strict organization or structure. A mind map more closely aligns with the way a lot of our brains work—participants can bounce from one thought to the next defining the relationships as they go.

Mind mapping to solve a problem includes, but is not limited to, these relatively easy steps:

• In the center of the page, add your main idea or concept (in this case, the problem).
• Branch out from the center with possible root causes of the issue. Connect each cause to the central idea.
• Branch out from each of the subtopics with examples or additional details about the possible cause. As you add more information, make sure you are keeping the most important ideas closer to the main idea in the center.
• Use Collaborative AI to generate or expand on your ideas, so your mind map is as complete as possible.

Alternatively, you could use mind maps to brainstorm solutions once you discover the root cause. Try our free mind map template  or add the mind map shape library to quickly start your own mind map.

Create a problem-solving flowchart

A mind map is generally a good tool for non-linear thinkers. However, if you are a linear thinker—a person who thinks in terms of step-by-step progression making a flowchart may work better for your problem-solving strategy. A flowchart is a graphical representation of a workflow or process with various shapes connected by arrows representing each step.

Whether you are trying to solve a simple or complex problem, the steps you take to solve that problem with a flowchart are easy and straightforward. Using boxes and other shapes to represent steps, you connect the shapes with arrows that will take you down different paths until you find the logical solution at the end.

Flowcharts or decision trees are best used to solve problems or answer questions that are likely to come up multiple times. For example, Yoder Lumber , a family-owned hardwood manufacturer, built decision trees in Lucidchart to demonstrate what employees should do in the case of an injury.

To start your problem-solving flowchart, follow these steps:

• Draw a starting shape to state your problem.
• Draw a decision shape where you can ask questions that will give you yes-or-no answers.
• Based on the yes-or-no answers, draw arrows connecting the possible paths you can take to work through the steps and individual processes.
• Continue following paths and asking questions until you reach a logical solution to the stated problem.
• Try the solution. If it works, you’re done. If it doesn’t work, review the flowchart to analyze what may have gone wrong and rework the flowchart until you find the solution that works.

If your problem involves a process or workflow , you can also use flowcharts to visualize the current state of your process to find the bottleneck or problem that’s costing your company time and money.

Lucidchart has a large library of flowchart templates to help you analyze, design, and document problem-solving processes or any other type of procedure you can think of.

Draw a cause-and-effect diagram

A cause-and-effect diagram is used to analyze the relationship between an event or problem and the reason it happened. There is not always just one underlying cause of a problem, so this visual method can help you think through different potential causes and pinpoint the actual cause of a stated problem.

Cause-and-effect diagrams, created by Kaoru Ishikawa, are also known as Ishikawa diagrams, fishbone diagrams , or herringbone diagrams (because they resemble a fishbone when completed). By organizing causes and effects into smaller categories, these diagrams can be used to examine why things went wrong or might go wrong.

To perform a cause-and-effect analysis, follow these steps.

1. Start with a problem statement.

The problem statement is usually placed in a box or another shape at the far right of your page. Draw a horizontal line, called a “spine” or “backbone,” along the center of the page pointing to your problem statement.

2. Add the categories that represent possible causes.

For example, the category “Materials” may contain causes such as “poor quality,” “too expensive,” and “low inventory.” Draw angled lines (or “bones”) that branch out from the spine to these categories.

3. Add causes to each category.

Draw as many branches as you need to brainstorm the causes that belong in each category.

Like all visuals and diagrams, a cause-and-effect diagram can be as simple or as complex as you need it to be to help you analyze operations and other factors to identify causes related to undesired effects.

Collaborate with Lucidchart

You may have superior problem-solving skills, but that does not mean that you have to solve problems alone. The visual strategies above can help you engage the rest of your team. The more involved the team is in the creation of your visual problem-solving narrative, the more willing they will be to take ownership of the process and the more invested they will be in its outcome.

In Lucidchart, you can simply share the documents with the team members you want to be involved in the problem-solving process. It doesn’t matter where these people are located because Lucidchart documents can be accessed at any time from anywhere in the world.

Problem-Solving Flowcharts is a graphical representation used to break down problem or process into smaller, manageable parts, identify the root causes and outline a step-by-step solution. 

It helps in visually organizing information and showing the relationships between various parts of the problem.

This type of flowcharts consists of different symbols and arrows, each representing different components or steps in the problem-solving process. 

By following the flow of the chart, individuals or teams can methodically approach problem, analyze different aspects of it and come to a well-informed solution.

Problem-Solving Flowcharts is a versatile tool that can be used in various scenarios. Here’s when to consider utilizing one:

• Complex Problems: When faced with a multifaceted issue that involves multiple steps or variables, flowcharts can help break down the complexity into digestible parts.
• Team Collaboration: If you’re working with a team and need a common understanding of problem and its potential solutions then a flowchart provides a visual that everyone can refer to.
• Analyzing Processes: In a situation where you need to understand a particular process, whether it’s within a project or a part of regular operations then mapping it out in a flowchart can offer clarity.
• Decision Making: When various paths or decisions might be taken, a flowchart can outline the potential outcomes of each aiding in making an informed choice.
• Training and Onboarding: Flowcharts can be used in training materials to help new employees understand complex processes or procedures which makes the learning curve smoother.
• Identifying Root Causes: If you’re looking to identify the underlying causes of problem then a flowchart can facilitate a systematic approach to reaching the root of the issue.

Problem-solving flowcharts can offer several benefits to the users who are looking to solve a particular problem. Few advantages of flowcharts in problem solving are: 

Visual Clarity

When you’re dealing with multifaceted problems or processes, words alone can make the situation seem even more tangled. Flowcharts distill these complexities into easily understandable visual elements. 

By mapping out each phase or component of problem, flowcharts offer a bird’s eye view enabling individuals to grasp the bigger picture and the finer details simultaneously.

Sequential Representation

Flowcharts excel in laying out the sequence of events or actions. By indicating a clear starting point and illustrating each subsequent step, they guide users through a process or solution path methodically. 

This linear representation ensures that no step is overlooked and each is executed in the right order.  

Collaboration

Problem-solving often requires team effort and flowcharts are instrumental in fostering collaborative environments. 

When a team is discussing potential solutions or trying to understand problem’s intricacies, a flowchart serves as a collective reference point. 

It aids in synchronizing everyone’s understanding, minimizing miscommunications and promoting constructive discussions.

1. Define the Problem  

Before anything else, it’s essential to articulate the problem or task you want to solve clearly and accurately. By understanding exactly what needs to be addressed you can ensure that subsequent steps align with the core issue.

2. Identify the Inputs and Outputs  

Determine what inputs (such as data, information or resources) will be required to solve the problem and what the desired outputs or outcomes are. Identifying these factors will guide you in structuring the steps needed to reach the end goal and ensure that all necessary resources are at hand.

3. Identify the Main Steps  

Break down the problem-solving process into its main steps or subtasks. This involves pinpointing the essential actions or stages necessary to reach the solution. Create a roadmap that helps in understanding how to approach the problem methodically.

4. Use Decision Symbols  

In problem-solving, decisions often lead to different paths or outcomes. Using standard symbols to represent these decision points in the flowcharts allows for a clear understanding of these critical junctures. It helps visually present various scenarios and their consequences.

5. Add Descriptions and Details  

A well-designed flowcharts is concise but clear in its labeling. Using arrows and short, descriptive phrases to explain what happens at each step or decision point ensures that the flowcharts communicates the process without unnecessary complexity. 

6. Revise and Refine  

Creating a flowcharts is not always a one-and-done process. It may require revisions to improve its clarity, accuracy or comprehensiveness. Necessary refinement ensures that the flowcharts precisely reflects the problem-solving process and is free from errors or ambiguities.

7. Use Flowchart Tool  

While it’s possible to draw a flowcharts manually, using a flowcharts tool like Venngage’s Flowchart Maker and Venngage’s Flowchart Templates can make the process more efficient and flexible. These tools come with pre-designed templates and intuitive interfaces that make it easy to create, modify and share flowcharts. 

5 different types of problem-solving flowcharts 

Let’s have a look at 5 most common types of flowcharts that individuals and organizations often use. 

1. Process Flowchart s

A process flowcharts is a visual representation of the sequence of steps and decisions involved in executing a particular process or procedure. 

It serves as a blueprint that showcases how different stages or functions are interconnected in a systematic flow and it highlights the direction of the process from its beginning to its end.

Process flowcharts are instrumental in training and onboarding, sales process , process optimization, documentation, recruitment and in any scenario where clear communication of a process is crucial.

2. Flowcharts Infographic 

A flowcharts infographic is a great way to showcase the process or a series of steps using a combination of graphics, icons, symbols and concise text. It aims to communicate complex information in a clear and easy-to-understand manner, making it a popular tool for conveying information, data and instructions in a visually engaging way.

For example, you can use this flowchart to illustrate a health insurance process that visually explains the steps involved from finding a provider to paying for your healthcare provider. 

3. Circular Flowcharts

A circular flowcharts is used to illustrate the flow of information, goods, services or money within a closed system or process. It gets its name from its circular shape, which emphasizes the continuous and cyclical nature of the flow. 

Circular flowcharts are widely used in various fields such as economics, business, engineering and process management to help visualize and understand complex systems.

In a circular flowcharts , elements are represented using various shapes and connected with arrows to indicate the direction of flow. The circular arrangement indicates that the process is ongoing and repeats itself over time.

4. Swimlane flowcharts

Swimlane flowcharts , also known as cross-functional flowcharts are a specific type of flowchart that organizes the process flow into lanes or “swimlanes.” 

Each lane represents a different participant or functional area involved in the process and the flowchart shows how activities or information move between these participants. 

Swimlane flowcharts are particularly useful for illustrating complex processes that involve multiple stakeholders or departments.

In a swimlane flowcharts, the process is divided horizontally into lanes and each lane is labeled with the name of the department, person or role responsible for that part of the process. Vertically, the flowchart displays the sequence of steps or actions taken in the process.

5. Decision Flowchart s

Decision flowcharts, also known as decision trees or flow diagrams are graphical representations that illustrate the process of making decisions or solving problems. 

They are widely used in various fields such as computer science, business mapping , engineering and problem-solving scenarios. 

Decision flowcharts help break down complex decision-making processes into simple, sequential steps, making it easier to understand and follow.

A decision tree is a specialized flowchart used to visually represent the process of decision-making. 

Businesses and other individuals can employ a decision tree analysis as a tool to aid in evaluating different options and the possible consequences associated with each choice.

Decision trees Infographics can be used to create a more nuanced type of flowchart that is more informative and visually appealing by combining a decision flowchart and the flowchart infographic. 

Decision flowcharts are valuable tools for visualizing decision-making processes, analyzing complex problems and communicating them effectively to others.

Designing effective problem-solving flowcharts involves careful consideration of various factors to ensure clarity, accuracy and usability. Here are some best practices to create efficient and useful problem-solving flowcharts:

• Understand the problem first & clearly define it
• Keep it simple
• Use standard & recognizable symbols
• Ensure that the flowchart follows a logical and sequential order
• Clearly label each decision point, action and outcome
• Verify the flowchart’s accuracy by testing it
• Clearly state the decision criteria that lead to different branches
• Provide context when the flowchart is part of a larger process or system
• Review and revise the flowchart

Is flowchart the representation of problem solutions?

Flowcharts are not the representation of problem solutions per se; rather, they are a visual representation of processes, decision-making steps and actions taken to arrive at a solution to problem.

What are the 3 basic structures of flowcharts?

3 Basic Structures of Flowcharts are:

• Sequence: Simplify Complexity
• Selection (Decision): Embrace Choices
• Repetition (Loop): Emphasize Iteration

What are the elements of a good flowchart?

A good flowchart should exhibit clarity and simplicity, using consistent symbols and labels to depict a logical sequence of steps. It should be readable, with appropriate white space to avoid clutter while eliminating ambiguity through well-defined decision criteria and paths.

How to create a problem-solving flow chart

Problem-solving is one of those topics that we’ve often discussed on this site (check out our Problem Solving guide ). We think it’s one of  THE  vital skills of business. Why? Because you’ll come across problems every day, and you need to arm yourself with the right tools to solve them.

A problem-solving flowchart is one of those tools. It’ll help you take a problem statement, break the problem down into likely causes helping you get to the bottom of what’s gone wrong.

In this post, we’ll cover

• What is a Problem Solving Flow Chart
• How to create a Problem Solving flow chart
• Example 1 of Problem Solving flow chart
• Example 2 of Problem Solving Flow chart
• What flow chart shapes to use
• When should you use a flow chart
• 7 tips on creating your Problem Solving chart

Key Benefits & Likely issues with the tool

Let’s get started!

What is a Problem Solving Flowchart

A Problem Solving flow chart is a diagram that uses shapes, arrows, and text to show a moving sequence of actions and/or activities that help solve a problem.  

How to create a Problem Solving flowchart

• Describe your problem.
• Pose Yes/No Questions that can help identify the cause of the problem
• Question each stage of the process until it is fully examined
• Repeat steps 2 & 3 until you have identified a solution
• Try the solution; if it is successful in addressing the root cause, then you’ve fixed your problem. If not, repeat the process until you have a solution that works.

A problem-solving flowchart attempts to identify a root cause/solution to the trigger that is causing the problem allowing you to change the process and prevent the problem from occurring. 

Let’s now demonstrate the effectiveness of a problem solving flowchart by showing some examples.

Example 1 Problem solving flow chart

In our first example, we’re going to start with something simple to show you the principle of the tool.

We have been given a cup of tea and we don’t like it!  

Let’s use a problem-solving flow chart to find out what’s gone wrong.

We’ve used Excel to capture this flow chart using flowchart shapes (insert –> shapes), you can, of course, use other applications to do this, you don’t’ have to have specialized flow chart software to do this. ( there’s a great flowchart in Excel video here ). Or you can simply use a pen and paper.

Use a rectangle and add your problem statement.

Remember to keep your problem statement unambiguous and straightforward. Here we’ve used “I don’t like my cup of tea.”

Now that we’ve got our problem statement, we’re going to start asking questions.

We’re going to examine the variables that go into a cup of tea in an attempt to find out what’s gone wrong.

** TIP** – Work through your process – rather than start from scratch, if you have a documented process, work through that examining each step to ascertain if there are issues. If not, you might find it useful to research and sketch out the process before starting with your flowchart.

We have a process for the cup of tea, which is:

1/ Boil Water

2/ Place Breakfast Tea teabag in the cup

3/ Add Water

4/ Leave to sit for 2 mins

4/ Remove teabag

5/ Add milk

6/ Add sugar

So our problem solving flow chart needs to examine each of those steps to determine where the failure has occurred. 

We’ll add a question shape (diamond), connect out problem statement to it using an arrow to check if we boiled the kettle. Our Diagram will now look like:

As a question, we want two possible routes – Yes and No.

Our process asks us to boil the kettle if we did, and the answer is Yes, then we can go to the next process step.

If the answer is No, then we have a problem. Our tea will be cold. 

Here we can do one of two things. We can terminate the flow chart, or we can add an activity to rectify the problem (this might be to remake the drink or to perhaps heat the drink up in the microwave).

Our flow chart now looks like this:

Step 2 in our Tea making process was to add a Breakfast-tea tea bag.

So, once again, we’ll ask a question about that step.

“Did we add an English Breakfast teabag.”

As before, we’ll use a question shape, using Yes or No answers. If we performed the process step correctly, we’d move on. If we didn’t, we’ll either end the problem solving (we’ve found the root cause), or we’ll add a corrective action.

Now we’ll repeat this process until we’ve reviewed the whole process.

Our finished flowchart looks like this.

However, we’re not finished.

What happens if we follow the flow chart, and we find we didn’t use boiled water. We remake the tea using boiled water, and we still don’t like it?  

We need to ask some further questions.

We need to update our flow chart to validate that we solved the problem and what to do if we didn’t.

So for each step of the process, our problem solving flowchart now looks like this.

Here’s our completed flow chart.

As you can see, we’ve identified the problem, and we’ve described a corrective action.

But there’s a problem here. With this flowchart, you can still follow it, validating the process, and still end up with a cup of tea that’s unsatisfactory. 

Why is that?

Well, it’s perfectly possible that we started out with a process that’s incorrect. What happens if the process called for using an incorrect tea bag from the start?

So we’ll simplify things by adding a block at the end that if you’re still not happy at the end of reviewing the steps, a full review of the process will be undertaken. This is a simple answer to this problem, and I would expect that you would expand this section in more detail if you were creating a flowchart yourself.

So what does a more complex process look like, how about we look at a business problem?

Example 2 Problem Solving flow chart

OK, so example 1 may have been a bit simple, and you are maybe looking for something in a business context.

So in Example 2, let’s look at a scenario that’s a little more complex.

Let’s assume that your organization has received a non-conforming part. You have been assigned to work with the Vendor to:

• Find out what went wrong
• Prevent recurrence

We’re going to use a problem solving flow chart to help us do that.

As with the first example, we’re going to state the problem.

“The part is non conforming.”

Using the production process from the Vendor, we’ll work through the stages to see if we can spot what’s gone wrong.

The diagram below shows an analysis of the first two steps of the production process using a problem-solving flow chart.

The first thing you’ll notice is that on one process step, there may be many questions to ascertain the potential issue.  

Some of these may be complex and require careful thought.

There may be multiple variables (systems, processes, tools, inputs, etc.) that may require attention.

You will need to analyze each process step, in full, to be sure you have caught all the possible causes of the fault.

Which Flow chart shapes should you use.

A problem solving flow chart usually utilizes only a small number of shapes. We show these in the table below.

When should you use a Problem Solving flow chart

There are many many problem tools available.

A flow chart lends itself to be used when:

• You are looking for a tool that is simple to use
• You are looking to use a tool that does not require complex software
• You want to validate a  process.
• You want something that facilitates collaboration
• You want something that you can use to communicate with others

7 Tips on creating great problem solving flow charts

1/ Use standard shapes!

2/ Make it easy to follow!

3/ Keep things on one page

4/ Don’t overload your boxes with text

5/ Go into enough detail. Don’t try and simplify activities as it might hide problems from being seen.

6/ Collaborate. Where you can utilize a team to help document the problem and the activities do so. The more knowledge of the process, the better chance you’ll have of locating the issue.

7/ Use a consistent direction to flow your process, moving things around the page can confuse people who might look at it.

A flow chart can provide you with a great advantage when looking to solve problems. Some of the key benefits include

• A visual aide that’s easy to understand
• Simple to use, does not require hours and hours of training
• A tool that facilitates collaboration
• Effective for aiding communication
• Provides an effective method of analysing a process

However, as with everything, there are some issues to look out for

• Flowchart fails to capture all process steps and therefore root cause analysis is hit and miss
• Lack of knowledge of the process by the individual compiling the flowchart results in inaccurate problem solving
• Inconsistent flow of process makes maps confusing
• Complex processes may be better suited to other tools (fishbone etc)
• Inconsistent formatting and/or use of shapes result in flowchart that is difficult to utilise.

There are a great many tools out there for problem-solving, and flow charts can be used either as a stand-alone tool or conjunction with one of these other tools.

Flowcharts can make for a great problem-solving tool.  

They’re simple to use, effective, and facilitate collaboration.

Flow Charts

Identify and communicate your optimal process.

By the Mind Tools Content Team

How often have you thought about streamlining a process in your organization but not been sure where to start? Or perhaps you've struggled to understand a process when it's described to you in detail.

Flow charts are a useful tool in these situations, as they make a process easy to understand at a glance. Using just a few words and some simple symbols, they show clearly what happens at each stage and how this affects other decisions and actions.

In this article and video, we look at how to create and use flow charts, and explore how they can help you to solve problems in your processes.

What Is a Flow Chart?

Flow charts are easy-to-understand diagrams that show how the steps of a process fit together. American engineer Frank Gilbreth is widely believed to be the first person to document a process flow, having introduced the concept of a "Process Chart" to the American Society of Mechanical Engineers in 1921.

Flow charts tend to consist of four main symbols, linked with arrows that show the direction of flow:

1. Elongated circles, which signify the start or end of a process.

2. Rectangles, which show instructions or actions.

3. Diamonds, which highlight where you must make a decision.

4. Parallelograms, which show input and output. This can include materials, services or people.

You can use many other symbols in a flow chart but remember that these diagrams are used for communication . If you use symbols that only a few people understand, you may fail to get your message across. So, be sure to keep things simple !

When to Use a Flow Chart

All manner of organizations use flow charts to:

• Define a process.
• Standardize a process.
• Communicate a process.
• Identify bottlenecks or waste in a process.
• Solve a problem .
• Improve a process.

For example, software developers can use them to work out how the automated and manual parts of a process join up. Inexperienced team members might follow a flow chart to help them to complete activities in the right order. A manufacturer could ensure that it keeps to its values by applying a quality-control flow chart that presents questions and decision points. And an HR department might combine a flow chart with an organogram to show people who to contact about issues and when.

Why Use Flow Charts?

This tool's simplicity makes communicating and documenting a process quick and clear, so that the process will more likely be understood and applied correctly and consistently. It can also help you to estimate the timescale of the process, as you're better able to gauge the time needed for each task along the way. And you'll more likely identify who you should involve and at what stage, such as senior management or a compliance authority.

But you can also benefit from the process of creating a flow chart itself, as you build it step by step. You'll be able to focus on the detail of each individual stage, without feeling overwhelmed by the rest of the process, and then "zoom out" again to see the wider picture.

If your process or project involves several people or teams, you might find it more useful to use a Swim Lane Diagram rather than a flow chart – this helps you to show process flows between people and teams.

How to Create a Flow Chart

Follow these four steps:

Step 1: Identify Tasks

Begin by listing all of the tasks in a process in chronological order. Ask questions such as, "What happens next in the process?" or, "Do you need to make a decision before the next step?" or, "What approvals are required before you move on to the next task?"

Put yourself in the shoes of the person using the process, possibly for the first time. Talk to team members who work with the process directly, and get their opinions on where improvements could be made. Better yet, take a hands-on approach and go through the procedure yourself, and think about the practicalities of each stage. Use Customer Experience Mapping if your flow chart focuses on customer service, so that you can gain a better understanding of the process.

Step 2: Organize and Document Tasks

Next, start your flow chart by drawing the elongated circle shape and labeling it "Start."

Then, work through your whole process, and show the actions and decisions in the order that they happen. Link them with arrows to illustrate the flow of the process.

Where you need to make a decision, draw arrows from the decision diamond to each possible solution, and then label each arrow with the decision made. Remember to show the end of the process by using an elongated circle labeled "Finish."

Step 3: Double-Check the Process

When you've completed your flow chart, go back to the start and try it out to make sure that you haven't overlooked anything. Work through each step, and ask yourself whether you've represented the sequence of actions and the decisions involved correctly. Are there more decisions to be made at certain stages?

Then show your flow chart to other people, especially those who work directly with the process. Ask them to test that it works and to tell you if there are any problems or omissions.

Step 4: Challenge the Flow Chart

Finally, you might want to improve the process rather than just record it. So, see whether any of the steps that you've described are unnecessary or overly complicated. Identify any major bottlenecks , and deal with them to improve performance.

Are there any missing steps, no matter how small or seemingly insignificant, that you should add? And have you assigned tasks and decisions to the right people or automated them where it's most appropriate? Make any changes and then challenge the chart again.

As you challenge your flow chart, you might also be challenging your team members' tried and tested ways of working. So, take time to win support for your ideas, and don't expect to change people's habits overnight.

You may find that SIPOC diagrams will give you the detailed information that you need to introduce change in a controlled and effective way.

Flow Chart Software

You'll likely start with drawing flow charts by hand, but it's often more convenient to use a diagramming app to save, amend and share your charts.

Such apps vary from the simple and free, such as draw.io , creately and Pencil Project , to the more complex and paid-for, such as gliffy™ , Lucidchart , SmartDraw™ , and Visio® .

Flow charts can quickly become long and complicated, so that you can't represent them on a single piece of paper. This is where you can use "connectors" (shown as numbered circles) to link the flow when moving from one page to another. The user can follow the matching numbers to trace the flow of the process.

The image below shows part of a flow chart for how the receptionists in an example company should route incoming phone calls to the correct department:

Flow charts are simple diagrams that map out a process, so that you can easily communicate it to other people. You can also use them to define and analyze a process, build a step-by-step picture of it, and then standardize or improve it.

To draw a flow chart, identify the tasks and decisions that you make during a process, and write them down in order.

Then, arrange these steps in the flow chart format, using the appropriate symbols.

Finally, check and challenge your flow chart to make sure that it accurately represents the process, and that it shows the most efficient way of doing the job.

Flowchart Tutorial (with Symbols, Guide and Examples)

A flowchart is simply a graphical representation of steps. It shows steps in sequential order and is widely used in presenting the flow of algorithms, workflow or processes. Typically, a flowchart shows the steps as boxes of various kinds, and their order by connecting them with arrows.

What is a Flowchart?

A flowchart is a graphical representations of steps. It was originated from computer science as a tool for representing algorithms and programming logic but had extended to use in all other kinds of processes. Nowadays, flowcharts play an extremely important role in displaying information and assisting reasoning. They help us visualize complex processes, or make explicit the structure of problems and tasks. A flowchart can also be used to define a process or project to be implemented.

Flowchart Symbols

Different flowchart shapes have different conventional meanings. The meanings of some of the more common shapes are as follows:

The terminator symbol represents the starting or ending point of the system.

A box indicates some particular operation.

This represents a printout, such as a document or a report.

A diamond represents a decision or branching point. Lines coming out from the diamond indicates different possible situations, leading to different sub-processes.

It represents information entering or leaving the system. An input might be an order from a customer. Output can be a product to be delivered.

On-Page Reference

This symbol would contain a letter inside. It indicates that the flow continues on a matching symbol containing the same letter somewhere else on the same page.

Off-Page Reference

This symbol would contain a letter inside. It indicates that the flow continues on a matching symbol containing the same letter somewhere else on a different page.

Delay or Bottleneck

Identifies a delay or a bottleneck.

Lines represent the flow of the sequence and direction of a process.

When to Draw Flowchart?

Using a flowchart has a variety of benefits:

• It helps to clarify complex processes.
• It identifies steps that do not add value to the internal or external customer, including delays; needless storage and transportation; unnecessary work, duplication, and added expense; breakdowns in communication.
• It helps team members gain a shared understanding of the process and use this knowledge to collect data, identify problems, focus discussions, and identify resources.
• It serves as a basis for designing new processes.

Flowchart examples

Here are several flowchart examples. See how you can apply a flowchart practically.

Flowchart Example – Medical Service

This is a hospital flowchart example that shows how clinical cases shall be processed. This flowchart uses decision shapes intensively in representing alternative flows.

Flowchart Example – Simple Algorithms

A flowchart can also be used in visualizing algorithms, regardless of its complexity. Here is an example that shows how flowchart can be used in showing a simple summation process.

Flowchart diagrams — What they are and how to use them

February 7, 2024 by katieadelson

In today’s day and age, information overload is a constant challenge. The need for clear and concise ways to present complex ideas has become more important than ever.  

F lowchart diagrams have emerged as a powerful tool to simplify ideas, streamline workflows, and improve understanding.  

Studies have shown that visual aids, such as flowchart diagrams, can improve comprehension by up to 400% compared to text-only explanations. 

Are you an entrepreneur, a student, or a professional seeking to enhance your problem-solving and decision-making skills?  

If so, this blog will provide you with everything you need to understand flowchart diagrams and how to utilize them. 

What is a flow chart?  

Flowchart diagrams are visual representations that help show the steps and decision-making processes of a system, concept, or procedure.  

They use symbols and arrows to show the flow of information or actions, making complex processes easier to understand. 

A flowchart consists of shapes connected by lines, each representing a specific action or decision.  

The shapes typically used in flowcharts include rectangles, diamonds, ovals, and parallelograms. These shapes are chosen based on the specific purpose of the flowchart and convey different meanings. 

By visualizing these steps sequentially as a series of text-filled symbols or shapes, flowcharts can show you: 

• How to reach your goal, step-by-step. 
• What tasks need to be completed as part of the process. 
• Where decisions need to be made, and what happens next. 

Flowcharts make it easier for teams to follow work processes. They’re a powerful alignment tool that can be used to help you create, document, analyze, or improve the way work gets done. 

A brief history of flowcharts  

Flowcharts have a long history. They have been widely used for decades in various fields to visualize processes and workflows.  

The concept of visualizing processes using graphical symbols can be traced back to ancient civilizations, such as the Egyptians and Greeks. They employed diagrams and drawings to represent organizational systems and workflows. 

In the modern context, the credit for creating and popularizing flowcharts can be attributed to Frank Gilbreth and Lillian Gilbreth, pioneers in the field of industrial engineering.  

In the early 20th century, the Gilbreths introduced a system called “ Process Charts ” to analyze and improve workflow efficiency in industrial settings.  

These process charts utilized symbols and arrows to depict the flow of materials and information in a process. 

However, it wasn’t until the 1940s that the concept of flowcharts gained actual popularity. During this period, flowcharts became an essential tool in computer programming as they helped programmers visualize and understand complex algorithms and programs.  

Over the years, flowcharts have evolved. Now, many symbols have standard meanings to ensure consistency and clarity, such as:  

• Rectangles used to show processes. 
• Diamonds to portray decisions. 
• Oval shapes pinpoint the start or end of a flowchart. 
• Parallelograms to represent input/output or data storage. 
• Arrows for workflows and more. 

In the present day, flowcharts are widely used in diverse industries. They enable teams and stakeholders to understand, analyze, and communicate complex processes, identify issues, and find solutions for improvement. 

How to use a flowchart  

You can use a flowchart template to solidify personal or team objectives across various business activities. They’re often the tool of choice for explaining complex procedures without the technical jargon. 

Here are a few flowchart examples outlining areas where these step-by-step diagrams come in especially handy: 

• Project management and planning . Starting a project? You’ll find flowcharts an invaluable aid – especially during the planning stage. Use your diagram to ease collaboration between individuals or departments as you map out the steps your team needs to take. 
• Program, product, or system design . Designing something new comes with a unique set of challenges. Using a flowchart diagram can help level the playing field when your group is venturing through uncharted territory together. For example, when you’re tasked with creating a great user experience design. 
• Workflow documentation . Documenting a workflow or process with the help of a flowchart maker gives you a visual, readily available point of reference. This may help you get inspired, discuss a problem, make improvements, demonstrate compliance, or share knowledge with a new hire. 
• Process audit and decision-making . Troubleshooting, cost-cutting, and efficiency initiatives are all made easier by using flowcharts to study your options. Decision flowcharts (aka decision tree diagrams) are just one example of how you can review failed or inadequate processes from different angles. 

2 types of flowcharts  

There are various types of flowcharts and each type serves a different purpose and is used in different industries and fields.  

Below are three types of flowcharts that may be useful to improve your workflow: 

Type 1: Process map  

A process map is the most commonly used type of flowchart. It illustrates the steps or actions in a process, showing the sequence of tasks and decision points.  

Process maps are used to analyze and optimize business processes, identify issues, and communicate the process to stakeholders or higher-ups. They are widely used in various industries, such as manufacturing, logistics, healthcare, and project management. 

Type 2: Decision flowchart  

A decision flowchart, also known as a decision tree , represents a series of decisions and their possible outcomes. It visualizes the logic flow, allowing users to make decisions based on certain conditions or criteria.  

Decision flowcharts are commonly used in problem-solving, algorithm design, and decision-making processes across many fields, including programming, finance, and quality management. 

6 flowchart symbols to use in your diagrams   

In flowcharts, symbols represent different elements and actions involved in a process. These symbols provide visual clarity and help to communicate the flow of the process.  

These symbols interact with each other in a flowchart by connecting them with arrows that indicate the sequence of steps or actions. Arrows show the flow direction from one symbol to another, indicating the order in which the actions or tasks are performed.  

The flowchart continues until it reaches the end symbol. 

Symbols can be connected through multiple arrows, branching out to different paths based on decisions, or connecting back to previous steps to represent loops. The specific interaction between symbols in a flowchart depends on the representation process’s logic and requirements. 

Here are some common symbols used in flowcharts: 

1. Start and end symbol  

This symbol is represented by a rounded rectangle and signifies the beginning or end of the  

process. It is used to indicate the start and end points of the flowchart. 

2. Process symbol  

This symbol is represented by a rectangle and represents an action or operation that occurs within the process. It is used to describe the specific tasks or actions that need to be carried out. 

3. Decision symbol  

This symbol is represented by a diamond shape and is used to present a decision point or branching in the process. It represents a yes/no or true/false condition and usually has arrows pointing to possible outcomes. 

4. Input and output symbol   

This symbol is represented by a parallelogram and represents the input or output of data or information to or from the process. It signifies the interaction with external sources or systems. 

5. Connector symbol  

This symbol is represented by a small circle or a small rectangle and is used to link different parts of the flowchart. It is used when the flow needs to continue on a different page or when it needs to reference another part of the flowchart. 

6. Loop symbol  

This symbol is represented by a curved arrow or rectangle with curved sides, indicating a loop or repetition. It signifies that certain actions or tasks are repeated until a condition is met. 

9 steps to plan your flow chart   

Planning a new flow chart involves several key steps.  

Here are the steps presented as bullets: 

• Define objectives. Clearly outline the purpose and goals of the flow chart and identify what process or system the flow chart will represent. 
• Identify processes and activities . List the main processes and activities that need to be represented in the flow chart. Then,  break down complex processes into smaller, manageable steps. 
• Determine flow direction . Decide the flow direction (usually left to right or top to bottom). 
• Use standard symbols. Choose appropriate flow chart symbols for different elements such as processes, decisions, inputs, outputs, etc. 
• Define start and endpoints. Mark the start and end points of the process and indicate where the flow chart begins and where it concludes. 
• Establish connections. Connect processes and activities with arrows to represent the flow of information or actions. 
• Include decision points. Identify decision points within the process where choices need to be made and use decision diamonds to represent these decision points. 
• Get feedback. Share the flow chart with relevant stakeholders to gather feedback. Incorporate suggestions and make improvements accordingly. 
• Finalize and document. Finalize the flow chart with the necessary adjustments. 

How to create a flowchart diagram in 4 steps  

Since the point of any flowchart is to clarify a process or flow of events, standardized symbols are the key to communicating in a “language” everyone will understand. 

As mentioned, the three most basic flowchart symbols include: 

• Oval shapes (indicate workflow start or endpoints). 
• Rectangle shapes (indicate individual steps). 
• Diamond shapes (indicate decision points). 

Here’s how to create a flowchart diagram in four easy steps. 

1. Establish the purpose of your flowchart  

List out the various steps you’ll need to include. 

2. Use a labeled oval shape to represent the starting position of your process or workflow  

Then, with the list you just created, start at your oval and use arrowed lines to link the individual steps or tasks in the proper sequence. These steps should be represented by rectangles with brief, text-based descriptions inside. 

Use diamond shapes to indicate where decisions will be required in your process    

Use arrowed lines to link each diamond to new or repeated steps resulting from your decisions. 

Use a labeled oval shape to represent the end of your process or workflow  

And that’s it! 

Example of a flowchart diagram  

No matter how you use it, you’ll find a flowchart diagram equally effective, whether driving or supporting your initiative. 

Here’s a very simple example. 

Let’s say you and a friend want to create, stock, and sell originally designed t-shirts. Neither of you has run a business before, however, so you’re having trouble visualizing what the customer order process will look like. 

Since you need to finalize this part of your business plan before your bank loan appointment tomorrow, your friend suggests using a flowchart diagram to get a handle on your sales order workflow. 

You start by listing the steps you expect to take as part of this process.  

• Your customer places an order. 
• You pick the requested shirts from your inventory and set them aside. 
• You process your customer’s payment. 
• You package and ship their order. 
• The receipt of their delivery is confirmed. 
• You follow up to make sure your customer is satisfied. 

Next, you lay these steps out in your diagram using directional arrows and the appropriate flowchart symbols (in this case, ovals and rectangles).  

ORDER RECEIVED (process start point) > Stock picked > Payment processed > Order shipped > Delivery confirmed > CUSTOMER FOLLOW-UP (process end point) 

So far, so good. Here is what your simple flowchart would look like: 

You’re smart enough to realize, however, that t-shirt inventory levels will fluctuate, and not every customer payment transaction will clear. 

So, you identify where decisions will need to be made and use diamond shapes to edit and restructure your flowchart at two distinct points. 

H3: Point #1 

ORDER RECEIVED (process start point) > Product in stock?  

YES > Stock picked > Payment processed … 

NO > Additional inventory created > Product in stock?  

H3: Point #2 

ORDER RECEIVED (process start point) > Stock picked > Payment processed > Payment   

approved?  

YES > Order shipped … 

NO > Get new payment method from customer > Payment processed > Payment approved?  

NO > ORDER CANCELLED (new process endpoint) 

To design this process as clearly as possible for the benefit of both you and the bank, label the arrowed lines branching off your diamonds with the words YES or NO. Then, connect them to new rectangles or back to previous rectangles when earlier steps must be repeated. 

Following those steps, here is what your new flowchart would look like: 

Now, feeling much more confident about how your customer order process will play out, you finish your business plan , keep your bank appointment, and get the loan you need to start cranking out t-shirts. 

3 flowchart use cases  

Flowcharts are so versatile, we’re confident you’ll have no trouble finding ways you, your team, and your company can use and benefit from them – especially when you need to: 

• Lay out the processes for creating new products or systems. 
• Explore areas where quality or efficiency might be improved in an existing workflow. 
• Visualize the tasks or decisions that will go into planning your next project.  

If you need more help getting started, here are some additional flowchart examples in the form of use cases. 

1. Company A wants to improve its approach to sales training  

With sales department turnover high – and exit interviews showing departing reps weren’t always confident in their ability to close a sale – the company realizes they need to provide new sales hires with better training.  

They use a flowchart diagram to document their sales process from beginning to end and use it as the central talking point in onboarding sessions going forward. 

  As the company’s sales rep performance improves, turnover goes down, and revenues go up. 

2. Company B wants to create a simple but effective set of product instructions  

Despite its popularity, surveys show that many customers find the company’s flagship product difficult to assemble and operate.  

Determining they need instructions to simplify these processes for future buyers, the company prints flowchart diagrams that illustrate product assembly and troubleshooting procedures step-by-step. 

By providing these instructions with their product, the company soon finds they’re spending less time on after-sales support. 

3. Company C wants to customize its service  

The company has experienced great success with their basic house-cleaning service but receives many requests for add-ons like window washing and upholstery cleaning.  

Recognizing that customized packages will necessitate additional time, equipment, and staff, the company uses flowcharts to lay out revised workflow options and determine cost feasibility.  

Ultimately, they discovered that customizing their service isn’t financially viable right now. 

The company decides to put customization on hold until they’ve explored opportunities for outside investment.

Problem-solving – Flowchart example

The flowchart starts with identifying a problem. After the problem is identified, data is gathered and analyzed. Then, the solution is developed and the best solution is identified. If it isn’t successful, the solution development process starts again. If successful, the plan is implemented and is improved continuously.

Problem Solving

Today, we use computers in every field for various purposes. But, we know that they cannot solve the problems all by themselves. Furthermore, we have to give step by step instructions to the computer for solving the problem. We can define problem-solving as a process of understanding the problem, finding solutions for the problem, and finally implementing the solution to it. We can design the solution before coding in the form of algorithms and flowcharts. Moreover, the identification of arithmetic and logical operations is very important in developing the program.

Therefore, we can say that a successful problem-solving process depends on the following factors:

• understanding the problem and defining it precisely.
• designing proper algorithms and flowcharts of the solution.
• implementing the algorithm successfully.

When the problems are easy we can easily search out a solution. Whereas, complex problems require step by step process to solve. Hence, this means that we have to apply problem-solving techniques to solve the problem. Furthermore, this starts with finding a precise definition of the problem and ends with a successful solution. Moreover, the identification of arithmetic and logical operations plays a vital role while designing the algorithm. Here, we will study the algorithms and flowcharts.

Designing the solution

After understanding the relationship between input and output and the functionalities required we have to design an algorithm or flowchart. Furthermore, the algorithm should contain all the necessary functions to solve the problem. Moreover, it should produce a proper output for every input.

Hence, we can say that before writing the exact code for the problem it is necessary to define a solution. We can do this by starting with an initial plan and improvising it till it gives perfect results. Moreover, there can be more than one possible solution for a problem. Therefore, it is the responsibility of the programmer to choose the best solution.

While designing a problem we can represent it in algorithms and flowcharts. Hence, before writing the program code we can design the solution either in the form of an algorithm or a flowchart.

Introduction to Algorithms

An algorithm is basically a procedure of steps that we exactly follow to solve a particular task or problem. We can say that it is a set of rules that we need to follow while developing a program code during problem-solving. Furthermore, if we write an algorithm before actually writing a code, it becomes easy to perform the coding part. Moreover, the algorithm is in simple English language hence, others can also easily understand it and develop the code.

Features of an algorithm

The features of an algorithm are as follows:

The algorithm should be very clear and unambiguous in its meaning. It should be simple so that one can understand it easily.

• Well-defined inputs

A program may require to take input from the user. Therefore, the algorithm should clearly define the inputs.

• Well-defined outputs

The algorithm should clearly specify the output that the program will produce.

The algorithm should have a termination point. This means that the algorithm should not be such that it runs infinite times or end up in loops.

• Feasibility

The algorithm should be such that we can implement it easily. Hence, it should be simple and practical to implement.

• Language independent

It should be in simple English language. Since the code implementation should result in the same output no matter which programming language we use while writing the code.

Introduction to Flowcharts

It is basically a diagrammatic representation of an algorithm. Furthermore, it uses various symbols and arrows to describe the beginning, ending, and flow of the program. Moreover, the programmers use it to depicting the flow of data and instructions while problem-solving. F lowcharting is the process of drawing a flowchart for an algorithm.

Symbols in a flowchart

The flowchart uses various symbols in the representation. These basic symbols are as follows:

It represents the start, stop, or halt in a program’s flow. The flowchart always starts and ends with this symbol. Besides, we represent it using an oval shape.

Input/Output

We represent it using a parallelogram . It indicates any input from the user or output of the program.

We represent it using a rectangle . It indicates any arithmetic operation’s processing such as addition, subtraction, multiplication, division, etc.

We represent it using the diamond symbol. It represents any type of decision in a program that results in true or false. For example. if-conditions.

We represent it using a circle . Whenever a flowchart is too large we can use connectors to avoid confusion.

These are basically arrows that represent the flow of the program.

Algorithm and flowchart explained with examples, what is algorithm and flowchart.

Algorithm and flowchart are programming tools. A Programmer uses various programming languages to create programs. But before actually writing a program in a programming language, a programmer first needs to find a procedure for solving the problem which is known as planning the program. The program written without proper pre-planning have higher chances of errors. The tools that are used to plan or design the problem are known as programming tools. Algorithm and flowchart are widely used programming tools.

The word “algorithm” relates to the name of the mathematician Al- khowarizmi , which means a procedure or a technique. Programmer commonly uses an algorithm for planning and solving the problems.

An algorithm is a specific set of meaningful instructions written in a specific order for carrying out or solving a specific problem.

Types of Algorithm:

The algorithm and flowchart are classified into three types of control structures.

• Branching(Selection)
• Loop(Repetition)

According to the condition and requirement, these three control structures can be used.

In the  sequence structure, statements are placed one after the other and the execution takes place starting from up to down.

Whereas in branch control, there is a condition and according to a condition, a decision of either TRUE or FALSE is achieved. In the case of TRUE, one of the two branches is explored; but in the case of FALSE condition, the other alternative is taken. Generally, the ‘IF-THEN’ is used to represent branch control.

Write an algorithm to find the smallest number between two numbers

Write an algorithm to check odd or even number.

The Loop or Repetition allows a statements or block of statements to be executed repeatedly based on certain loop condition. ‘While’ and ‘for’ construct are used to represent the loop structure in most programming languages. Loops are of two types: Bounded and Unbounded loop. In bounded loop, the number of iterations is fixed while in unbounded loops the condition has to satisfy to end the loop.

An algorithm to calculate even numbers between 20 and 40

Write an algorithm to input a natural number, n, and calculate the odd numbers equal or less than n.

Characteristics of a good algorithm.

• The Finite number of steps:

After starting an algorithm for any problem, it has to terminate at some point.

• Easy Modification.

There can be numbers of steps in an algorithm depending on the type of problem. It supports easy modification of Steps.

• Easy and simple to understand

A Simple English language is used while writing an algorithm. It is not dependent on any particular programming language. People without the knowledge of programming can read and understand the steps in the algorithm.

An algorithm is just a design of a program. Every program needs to display certain output after processing the input data. So one always expects the result as an output from an algorithm. It can give output at different stages. The result obtained at the end of an algorithm is known as an end result and if the result is obtained at an intermediate stage of process or operation then the result is known as an intermediate result. Also, the output has to be as expected having some relation to the inputs.

The first design of flowchart goes back to 1945 which was designed by John Von Neumann . Unlike an algorithm, Flowchart uses different symbols to design a solution to a problem. It is another commonly used programming tool.

In general, a flowchart is a diagram that uses different symbols to visually present the flow of data. By looking at a flow chart one can understand the operations and sequence of operations performed in a system. This is why flowchart is often considered as a blueprint of a design used for solving a specific problem.

A flowchart is defined as a symbolic or a graphical representation of an algorithm that uses different standard symbols.

Flowchart Symbols:

Guidelines for drawing a flowchart.

• The Title for every flowchart is compulsory.
• There must be START and END point for every flowchart.
• The symbols used in flowchart should have only one entry point on the top. The exit point for symbols (except for decision/diamond symbol) is on the button.
• There should be two exit points for decision symbol; exit points can be on the bottom and one side or on the sides.
• The flow of flowchart is generally from top to bottom. But in some cases, it can also flow to upward direction
• The direction of the flow of control should be indicated by arrowheads.
• The operations for every step should be written inside the symbol.
• The language used in flowchart should be simple so that it can be easily understood.
• The flowlines that show the direction of flow of flowchart must not cross each other.
• While connecting different pages of the same flowchart, Connectors must be used.

Some examples of algorithm and flowchart.

Example1: To calculate the area of a circle

Step1: Start

Step2: Input radius of the circle say r

Step3: Use the formula πr 2 and store result in a variable AREA

Step4: Print AREA

Introduction

The student will learn how to design an algorithm using either a pseudo code or flowchart. Pseudo code is a mixture of English like statements, some mathematical notations and selected keywords from a programming language. It is one of the tools used to design and develop the solution to a task or problem. Pseudo codes have different ways of representing the same thing and emphasis is on the clarity and not style.

Pseudo Code

Pseudo code is an informal high-level description of the operating principle of a computer program or other algorithm. It is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed.

Pseudo code uses the structural conventions of a programming language, but is intended for human reading rather than machine reading. It typically omits details that are not essential for human understanding of the algorithm, such as variable declarations, system-specific code and some subroutines. The programming language is augmented with natural language description details, where convenient, or with compact mathematical notation.

The purpose of using pseudo code is that it is easier for people to understand than conventional programming language code, and that it is an efficient and environment-independent description of the key principles of an algorithm. It is commonly used in textbooks and scientific publications that are documenting various algorithms, and also in planning of computer program development, for sketching out the structure of the program before the actual coding takes place.

Example \(\PageIndex{1}\)

In the following example, the pseudo code is on program that can add 2 numbers together then display the result.

A flow chart is a type of diagram that represents an algorithm, workflow or process. It shows the steps in the form of boxes of various kinds and their order by connecting them with arrows. The diagrammatic representation illustrates a solution model to a given problem.

Flowcharts can be used in the analysis, design, documenting or managing a process or program in various fields. They are also used in designing and documenting complex processes or programs.

Flowchart building blocks

• They are represented as circles, ovals or rounded (fillet) rectangles. They contain the word “Start” or “End”, or another phrase signaling the start or end of a process, such as “submit inquiry” or “receive product”.
• They show “flow of control”. For example an arrow coming from one symbol and ending at another symbol represents that control passes to the symbol the arrow points to. The line for the arrow can be solid or dashed. The meaning of the arrow with dashed line may differ from one flowchart to another and can be defined in the legend.
• These are represented as rectangles.
• Subroutines are represented as rectangles with double-struck vertical edges. They are used to show complex processing steps which may be detailed in a separate flowchart.
• These are represented as a parallelogram.
• These are represented as a hexagon. They normally show operations which have no effect other than preparing a value for a subsequent conditional or decision step (see below).
• These are normally represented as a diamond (rhombus) showing where a decision is necessary. They commonly test a Yes/No question or True/False condition. It has two arrows coming out of it, usually from the bottom point and right point, one corresponding to Yes or True, and one corresponding to No or False.
• It is generally represented with a black blob, showing where multiple control flows converge in a single exit flow. A junction symbol will have more than one arrow coming into it, but only one going out.
• They are represented by an identifying label inside a circle. Normally used in complex or multi-sheet diagrams to substitute for arrows. For each label, the “outflow” connector must always be unique, but there may be any number of “inflow” connectors. In this case, a junction in control flow is implied.
• It is normally represented by a double transverse line with any number of entry and exit arrows.They can be used whenever two or more control flows must operate simultaneously. The exit flows are activated concurrently when all of the entry flows have reached the concurrency symbol. A concurrency symbol with a single entry flow is a fork; one with a single exit flow is a join.

All processes should flow from top to bottom and left to right.

Example \(\PageIndex{2}\)

Problem: Calculate and report the grade-point average for a class.

Discussion: The average grade equals the sum of all grades divided by the number of students.

• Output: Average grade
• Input: Student grades
• Processing: Find the sum of the grades; count the number of students; calculate average

PSEUDO CODE

Program: Determine the average grade of a class

Figure \(\PageIndex{1}\): The Average Grade of a Class Flowchart

This section covered the algorithm development tools, that is, the pseudo codes, flowcharts and how to design and develop them. These tools are not hinged to any programming language but can be implemented in any language of choice. Basically these are the initial steps of designing a program for any given task. Examples for both are given to try and show the learner how they look like. On the flow charts, it has further included the building blocks of a flow chart.

Flowchart In Programming

A flowchart is a diagrammatic representation of an algorithm. A flowchart can be helpful for both writing programs and explaining the program to others.

Symbols Used In Flowchart

Examples of flowcharts in programming.

1. Add two numbers entered by the user.

2. Find the largest among three different numbers entered by the user.

3. Find all the roots of a quadratic equation ax 2 +bx+c=0

4. Find the Fibonacci series till term≤1000.

Note: Though flowcharts can be useful for writing and analyzing a program, drawing a flowchart for complex programs can be more complicated than writing the program itself. Hence, creating flowcharts for complex programs is often ignored.

Flowcharts are nothing but the graphical representation of the data or the algorithm for a better understanding of the code visually. It displays step-by-step solutions to a problem, algorithm, or process. It is a pictorial way of representing steps that are preferred by most beginner-level programmers to understand algorithms of computer science, thus it contributes to troubleshooting the issues in the algorithm. A flowchart is a picture of boxes that indicates the process flow sequentially. Since a flowchart is a pictorial representation of a process or algorithm, it’s easy to interpret and understand the process. To draw a flowchart, certain rules need to be followed which are followed by all professionals to draw a flowchart and are widely accepted all over the countries.

What is FlowChart?

A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.

Flowchart symbols

Different types of boxes are used to make flowcharts flowchart Symbols. All the different kinds of boxes are connected by arrow lines. Arrow lines are used to display the flow of control. Let’s learn about each box in detail.

Uses of Flowcharts in Computer Programming/Algorithms

The following are the uses of a flowchart:

• It is a pictorial representation of an algorithm that increases the readability of the program.
• Complex programs can be drawn in a simple way using a flowchart.
• It helps team members get an insight into the process and use this knowledge to collect data, detect problems, develop software, etc.
• A flowchart is a basic step for designing a new process or adding extra features.
• Communication with other people becomes easy by drawing flowcharts and sharing them.

When to Use Flowchart?

Flowcharts are mainly used in the below scenarios:

• It is most importantly used when programmers make projects. As a flowchart is a basic step to make the design of projects pictorially, it is preferred by many.
• When the flowcharts of a process are drawn, the programmer understands the non-useful parts of the process. So flowcharts are used to separate sound logic from the unwanted parts.
• Since the rules and procedures of drawing a flowchart are universal, a flowchart serves as a communication channel to the people who are working on the same project for better understanding.
• Optimizing a process becomes easier with flowcharts. The efficiency of the code is improved with the flowchart drawing.

Types of Flowcharts

Three types of flowcharts are listed below:

• Process flowchart: This type of flowchart shows all the activities that are involved in making a product. It provides a pathway to analyze the product to be built. A process flowchart is most commonly used in process engineering to illustrate the relation between the major as well as minor components present in the product. It is used in business product modeling to help understand employees about the project requirements and gain some insight into the project.
• Data flowchart: As the name suggests, the data flowchart is used to analyze the data, specifically it helps in analyzing the structural details related to the project. Using this flowchart, one can easily understand the data inflow and outflow from the system. It is most commonly used to manage data or to analyze information to and fro from the system.
• Business Process Modeling Diagram: Using this flowchart or diagram, one can analytically represent the business process and help simplify the concepts needed to understand business activities and the flow of information. This flowchart illustrates the business process and models graphically which paves the way for process improvement.

Types of boxes used to make a flowchart

There are different types of boxes that are used to make flowcharts. All the different kinds of boxes are connected to one another by arrow lines. Arrow lines are used to display the flow of control. Let’s learn about each box in detail.

1. Terminal

This box is of an oval shape which is used to indicate the start or end of the program. Every flowchart diagram has an oval shape that depicts the start of an algorithm and another oval shape that depicts the end of an algorithm. For example:

This is a parallelogram-shaped box inside which the inputs or outputs are written. This basically depicts the information that is entering the system or algorithm and the information that is leaving the system or algorithm. For example: if the user wants to input a from the user and display it, the flowchart for this would be:

This is a rectangular box inside which a programmer writes the main course of action of the algorithm or the main logic of the program. This is the crux of the flowchart as the main processing codes is written inside this box. For example: if the programmer wants to add 1 to the input given by the user, he/she would make the following flowchart:

4. Decision

This is a rhombus-shaped box, control statements like if, condition like a > 0, etc are written inside this box. There are 2 paths from this one which is “yes” and the other one is “no”. Every decision has either yes or no as an option, similarly, this box has these as options. For example: if the user wants to add 1 to an even number and subtract 1 if the number is odd, the flowchart would be:

This arrow line represents the flow of the algorithm or process. It represents the direction of the process flow. in all the previous examples, we included arrows in every step to display the flow of the program. arrow increases the readability of the program.

6. On-Page Reference

This circular figure is used to depict that the flowchart is in continuation with the further steps. This figure comes into use when the space is less and the flowchart is long. Any numerical symbol is present inside this circle and that same numerical symbol will be depicted before the continuation to make the user understand the continuation. Below is a simple example depicting the use of On-Page Reference

Advantages of Flowchart

• It is the most efficient way of communicating the logic of the system.
• It acts as a guide for a blueprint during the program design.
• It also helps in the debugging process.
• Using flowcharts we can easily analyze the programs.
• flowcharts are good for documentation.

Disadvantages of Flowchart

• Flowcharts are challenging to draw for large and complex programs.
• It does not contain the proper amount of details.
• Flowcharts are very difficult to reproduce.
• Flowcharts are very difficult to modify.

Solved assignment problems – algorithms and flowcharts.

An algorithm is defined as sequence of steps to solve a problem (task) . The steps must be finite, well defined and unambiguous. Writing algorithm requires some thinking. Algorithm can also be defined as a plan to solve a problem and represents its logic. Note that an algorithm is of no use if it does not help us arrive at the desired solution

Algorithm characteristics

• It should have finite number of steps . No one can be expected to execute infinite number of steps.
• The steps must be in order and simple
• Each step should be defined clearly i.e. without un-ambiguity (without doubtfulness)
• Must include all required information
• Should exhibit at least one output

A flowchart is a pictorial (graphical) representation of an algorithm . A flowchart is drawn using different kinds of symbols. A symbol is used for a specific purpose. Each symbol has name.

Different algorithms have different performance characteristics to solve the same problem. some algorithms are fast. some are slow. some occupy more memory space. some occupy less memory space. some are complex and some algorithms are simple..

Logically algorithm, flowchart and program are the same.

Q1. Add 10 and 20

To solve this problem we will take a variable sum and set it to zero. Then we will take the two numbers 10 and 20 as input. Next we will add both the numbers and save the result in the variable sum i.e., sum = 10 + 20. Finally, we will print the value stored in the variable sum.

Algorithm (in simple English)

• Initialize sum = 0 (PROCESS)
• Enter the numbers (I/O)
• Add them and store the result in sum (PROCESS)
• Print sum (I/O)

Q2. Find the sum of 5 numbers

In this question we are asked to find the sum of 5 numbers. So, we will take two variables - sum and count and set both of them to zero. The sum variable will store the result while the count variable will keep track of how many numbers we have read.

To solve this problem we will use the concept of loop. In loop or iterative operation, we execute some steps repeatedly as long as the given condition is TRUE. In this case we will keep reading the input till we have read 5 numbers.

So, we first initialize sum and count to zero. Then we will take the input and store it in a variable n. Next we will add the value stored in n to sum and save the answer in sum.

i.e., sum = sum + n

Then we will increment count by 1 and check if count is less than 5. If this condition is TRUE then we will take another input. If the condition is FALSE then we will print the value stored in variable sum.

• Initialize sum = 0 and count = 0 (PROCESS)
• Enter n (I/O)
• Find sum + n and assign it to sum and then increment count by 1 (PROCESS)
• Is count < 5 (DECISION)
• if YES go to step 2 else Print sum (I/O)

Q3. Print Hello World 10 times

This problem is also solved using the loop concept. We take a variable count and set it to zero. Then we print "Hello World" and increment count by 1.

i.e., count = count + 1

Next we check if count is less than 10. If this is TRUE then we again print "Hello World" and increment the variable count. On the other hand if the condition if FALSE then we will stop.

• Initialize count = 0 (PROCESS)
• Print Hello World (I/O)
• Increment count by 1 (PROCESS)
• Is count < 10 (DECISION)
• if YES go to step 2 else Stop
