What is a flowchart?

A flowchart (or flow chart) is a diagram that illustrates a process, system or other sequential sets of steps. For this reason, almost all flowcharts can be considered process flowcharts (or process flow diagrams).

Flowcharts are used extensively in the computer programming field, but they can also be a useful way to visualize an organization, a job task or a business process.

Organizations of all types can use flowcharts for both internal and external purposes.

This is an example of an internal-focused flowchart. This basic flowchart can help customer support team members understand the business process involved or what they need to do when there’s an email or phone call from customers.

But flowcharts can also have usefulness as a type of content companies can create, such as this entertaining process flow diagram that helps readers understand whether a nap should be in their future.

Let’s take a look at the different types of flowcharts there are and how you can use the right one for your business communication needs. You will notice that we don’t include process flow diagram as one of the categories, as almost all flowcharts are process flowcharts of some kind.

Decision flowchart

Among the most immediately recognizable flowcharts, decision flowcharts are somewhat obvious in that they are used to help make decisions in the order they need to be made. Decision flowcharts include “yes” and “no” questions and answers as part of their flow.

Let’s take a look at some decision flowchart examples.

This decision flowchart is quite simple, but it provides an ideal example of the format with the questions that need to be asked and the order in which they should be posed presented clearly.

Workflow flowchart / Workflow diagram

A workflow flowchart shows decisions and actions that happen inside an organization as part of a work product, project, service or other goals, like fulfilling a customer order. They often show how different roles, teams or departments contribute to the product or service.

This workflow chart illustrates an IT troubleshooting process, but it’s easy to imagine how your organization could update it to help team members understand a process that they are likely to repeat regularly.

Swimlane flowchart

A swimlane flowchart is a type of workflow diagram that is always cross-functional and illustrates the order in which decisions or actions happen and the relationships between them.

Phases of the workflow are usually read from left to right or top to bottom, and distinct teams are displayed in rows or columns.

This is a good example of this type of cross-functional flowchart:

This swimlane flowchart is a good way to illustrate a complex process in your company that covers data or documents that may enter your organization through a few means but that need to be handled the same way.

Use case flowchart / Use case diagram

A use case diagram or use case flowchart illustrates the goals and interactions a customer has with a company, and it can include both external customers and internal users. One of the main purposes is to show the interactions between the company and external customers.

This use-case flow chart template isolates the major events involved in managing customer relationships, but it could easily apply to any event-based process flowchart that involves multiple organizational levels.

This use-case diagram shows the possible ways in which an ATM could be used, but it would be simple to customize a diagram like this to visualize an event-driven process in your company.

EDP flowchart / EPC diagram

An event-driven process or EDP flowchart (also called an EPC diagram, with EPC standing for event-driven process chain) is similar to a use case flowchart or diagram in that it focuses on customers or users.

But where EDP flowcharts are unique is that they narrow their focus on actions taken by users, which are often illustrated as “events” in the context of a process.

System flowchart or program flowchart

System flowcharts and program flowcharts describe how systems and programs function and interact. Some show processes and functions completed by computer systems, while others show how manual, paper, online, and disk drives interact as part of a process, such as how paper applications get input into databases that can then be accessed online.

This is a good example of a system flowchart, although it’s in the form of an infographic. This particular program flowchart illustrates how a payment program processes customer information and finalizes payments.

Data flow diagram or document flowchart

Data flowcharts (also called data flow diagrams) and document flowcharts illustrate how information and data flows within a system. Sometimes information is in documents, though the data in question can also reside within a database or other structure.

This is an example of how a data flowchart looks like:
