In this article, you will learn different types of flowcharts and how they are used for different purposes. You will also learn how to create great flowcharts with Sketchboard’s online flowchart maker in 4 steps.

What is a flowchart?

A flowchart is a visual description of the components -which are often sequential- of a process or workflow. Flowcharts are one of the most commonly used types of diagrams in diverse domains from software design to manufacturing and business development. Flowcharts can be created for different purposes in different forms. However, the fundamental idea of visualizing the steps of a process to communicate it more effectively is the same for all flowcharts.

Flowcharts can be as simple as a quick sketch on a piece of paper. They can also be quite complex, created by sophisticated software that depicts a comprehensive process with countless elements. A flowchart can be also named as flow chart, process flowchart, or process flow diagram.

Step 0: Why do you need a flowchart?

Flowcharts are very useful tools when there is a need to explain a certain activity and its sequential steps effectively. Although the main purpose stays the same, it is important to keep in mind that different use cases might require different types of flowcharts. Here is a quick list of different use cases of a flowchart.

Understanding the nature of a process

In today’s currently changing environment, it is not always straightforward to grasp a basic understanding of how things work. It can be a software design of an HR tool, hardware manufacturing process, or a decision-making process. Visualizing a process helps everyone to be on the same page. Flowcharts bring significant value when there is a need to develop a common understanding of how a particular process is done.

Creating a common perception between stakeholders

Some processes have too many steps that nobody can easily comprehend the big picture. Flowcharts step in these cases to develop a common understanding for everyone involved. They can either prepare everyone for an “aha!” moment or just work as a starting point for a deeper discussion. Making the flowchart high-level or more detailed can facilitate different conversations between stakeholders.

Improving or automating a process

To make something better, it is important to comprehend the current situation first. Flowcharts make it easier to identify bottlenecks during the improvement phase of a process. The “as is” version and improved version of the process can be visualized via flowcharts. In addition to that, different improvement ideas can be discussed and prototyped on the flowchart before implementation. They can save time during the planning and integration phases of the improvements.

Reporting and documenting

Many organizations are having internal or external audits for different purposes. Flowcharts are very common tools to document steps of a process for reporting. Flowcharts can efficiently explain an activity, a workflow, or a decision-making process to an outsider. Documentation of such critical processes can make reporting and controlling tasks easier and smoother.

Types of flowcharts

Flowcharts are categorized in various ways. As the flowchart concept finds broad use in different fields every day, the types are getting more diverse too. For example, Chaudhuri in his book Flowchart and Algorithm Basics classifies flowcharts into two categories:

• program flowchart is widely used to visualize the steps of how a computer program solves a problem
• system flowchart aims to depict how multiple solutions interact with each other in a broader system

With that said, there are more categories worth to mention such as the document flowchart that visualizes how a document is processed within a certain system, the data flowchart that depicts the data flow in the process.

Another categorization is based on how detailed the flowchart is:

• a macro flowchart or general flowchart provides a high-level picture
• a detailed flowchart includes an in-depth perspective

The swimlane diagram or swimlane flowchart is another type of flowchart that includes an additional layer where cross-functionality can be depicted through the “swimlanes”. Although named differently, there are more diagram types that are similar to flowcharts: such as Unified Modeling Language (UML).

It is also important to note that a flowchart is one of the process mapping tools that can be used for various purposes. However, other process mapping tools such as the suppliers-inputs-process-outputs-customers (SIPOC or COPIS) tool and value-stream maps can be more beneficial in some particular situations.

4-step guideline to create flowcharts

Regardless of the purpose of your flowchart, here is a 4-step guideline to create one.

Step 1: Clarify the purpose of the flowchart

Understanding the purpose of the flowchart is a very critical step. Decide which part of the system needs to be visualized. Then define the boundaries, starting and ending points of the flowchart. . When you deal with more complicated systems that are integrated with each other, defining where your flowchart starts and ends can be a little tricky. In this phase, you can already start considering which agents are included in the process.

It is also a good idea to clarify the target audience and purpose of your flowchart. For example: Do you need a flowchart to explain your process to new employees, or do you need it to improve the current workflow? Check out the “Why do you need a flowchart?” section above if you haven’t yet. Answer to this question can save a lot of time, and make your flowcharting experience smoother. Without defining the purpose and the target audience, it is not possible to decide how much detail you would like to include in your flowchart.

Step 2: Map out the process items of the flowchart

Once you clarify the frame of your flowchart, it is time to document the activities, actors, and decision points of the process. Create shapes for each activity between the beginning and the end. To clarify the roles in each activity, you can use swimlanes for every actor which can be particular people, job positions, or departments. There are different shapes to represent different types of items such as diamonds for decision points, boxes for activities, and so on. Start simple, then make it more detailed as you go.

Depending on the type of flowchart you would like to use, there are different flowchart symbols. Some diagram types such as Unified Modelling Language (UML) or Business Process Model and Notation (BPMN) diagrams have a more structured icon list with defined rules. On the other hand, you can build your own visual language with more creative icons if you like. Just keep in mind that

Step 3: Create connections between flowchart items

After the flowchart items are added to the canvas, it is time to place them in the right sequence and visualize the relationships. Use easy connections with lines and arrows to represent the order. You can move the items around to make sure the flowchart is clear to follow. If needed, add text to the connecting lines to explain the relationship. Depending on how detailed flowcharts you would like to have, you can use different types of lines and arrowheads to clarify the nature of the relationships between the flowchart components.

Connections are the fundamental components of every flowchart. If your purpose is to understand the nature of a sophisticated process, this phase is the core of your flowcharting experience. Once you understand how various components work together in the system, you are successful in your pursuit. Just make sure you put enough time and effort into this. So that you create a comprehensive first draft. Once your first version is ready, it is time to move forward to the last step.

Step 4: Review, share, receive feedback, and improve

No flowchart is perfect, that’s why pencils have erasers. When the first draft is good enough, ask your team members for comments. This is the step where a collaborative online whiteboard can make your life easier. Using the collaboration features such as comments or slack integration makes it easier to give and receive feedback. In agile workplaces, these iterative cycles can be overlapping. This means your team can be already involved in your flowcharting process from the first step, and continuously provide input to your in-progress drafts.

If your purpose is to improve the process you visualized, this is the core point of your flowchart creation process. This is the time where you can ideate multiple versions to initiate discussions. You can benchmark your versions with your current processes and your competitors’ processes. Then sharing it with a broader level of stakeholders to widen your perspective can make a difference. Don’t be afraid of having a couple of iterative rounds for further improvements.

Flowchart examples

There are countless use cases of flowcharts in almost every field such as software development, healthcare, education, engineering, and business development. In this section, you will find some useful examples that you can use as templates for inspiration.

Decision Flowchart

Decision-making is one of the fundamental processes for any kind of organization. As a tool for strategic decision-making, decision flowcharts are widely used to standardize the decision-making process. In addition to that, creating a flowchart to design a comprehensive decision flow for any problem saves a lot of time.

Decision flowcharts provide a comprehensive visual guide for the decision-makers to act on particular situations. When dealing with complex problems, making a decision flowchart can help to ensure that rational decisions are agreed upon and implemented on an organizational level.

Data Flow Diagram (DFD)

A data flow diagram (a.k.a. data flowcharts) aims to depict how data moves through a process in a system. Data flow diagrams doesn’t include any decision points (often represented by diamond shapes) instead, it visualizes how data is used as input and output in various processes.

As an alternative, Unified Modeling Language (UML) Activity diagrams can be used to represent data flow in a system and provide similar functionality. There are different notations to be used for data-flow diagrams. Use a flexible flowchart tool to ideate your data flow diagrams quickly with your team.

Workflow Flowchart

Workflow flowcharts are used to define particular business processes in an organization. The history of workflow charts goes back to Frederick W. Taylor (1856–1915) who is the founding father of scientific management (also known as Taylorism). The modern management approaches also utilizes workflow diagrams very often when there is a need to map out a certain business process for further improvements.

As an example, you can see a workflow diagram of a recruitment process above. Although there are different versions of the workflow diagrams depending on the purpose, they basically include activity shapes and arrows to represent the flow.

Swimlane Flowchart

Swimlane flowchart (a.k.a. swimlane diagram) is used to visualize responsibilities in a workflow. As a metaphor from swimming pools, swimlanes can be created vertically or horizontally. Effective use of swimlanes in a flowchart can deliver a very clear picture of roles and responsibilities within a process.

Swimlanes often represent a department, a unit, or a single job position. Other flowchart components are added to different swimlanes to distinguish the responsibilities of each activity item.
