History of Flowcharts

It is not clear who was the true inventor of flowcharts, but the first standardized documentation on flow chart was first introduced by Frank and Lillian Gilbreth. In 1921, the couple presented the graphic-based method in a presentation titled: “Process Charts: First Steps in Finding the One Best Way to do Work”, to members of the American Society of Mechanical Engineers (ASME).

After that, in 1930s, Allan H. Mogensen, an industrial engineer trained some participants in his Work Simplification Conferences in New York. Participants from this conference such as Art Spinanger and Ben Grahamthen began to use flowchart in their respective fields, which helped propagate the usage of flowchart.

In 1947, ASME adopted a symbol set derived from Gilbreth’s original work as the “ASME Standard: Operation and Flow Process Charts.”

In the year 1949, flowchart began to be used for planning computer programs and quickly became one of the most popular tools in designing computer algorithms and programs. Nowadays, flow chart is an important productivity tool, serving employees in various industries and functions.

What is a Flowchart used for?

Flowchart is a very versatile tool that can be used to:

  • Document a process
  • Present a solution
  • Brainstorm an idea
  • Design a system
  • Explain a decision making process
  • Store information

Flowchart Symbols & Components

Flowchart is a very intuitive method to describe processes. As such, in most cases, you don’t need to worry too much about the standards and rules of all the flow chart symbols. In fact, a simple flowchart, constructed with just rectangular blocks and flowlines, can already get most jobs done.

However, if you want to get technical and precise, there are preset rules and standards you can follow. Specifically, the American National Standards Institute (ANSI) set standards for flowcharts and their symbols in the 1960s. Afterwards, the International Organization for Standardization (ISO) adopted the ANSI symbols in 1970. In general, flowcharts flow from top to bottom and left to right. For a full list of flowchart symbols, read our Guide on Flowchart Symbols

1. Flowline: Shows the process’ direction. Each flowline connects two blocks.
2. Terminal: Indicates the beginning or end of a flowchart
3. Process: Represent a step in a process. This is the most common component of a flowchart.
4. Decision: Shows a step that decides the next step in a process. This is commonly a yes/no or true/false question.
5. Input / Output: Indicates the process of inputting or outputting external data.
‍6. Annotation / Comment: Indicates additional information regarding a step in a process.
‍7. Predefined Process: Shows named process which is defined elsewhere.
‍8. On-page Connector: Pairs of on-page connecter are used to replace long lines on a flowchart page.
‍9. Off-page Connector: An off-page connector is used when the target is on another page.
‍10. Delay: Any delay period that is part of a process
‍11. Alternate Process: An alternate to the normal process step. Flow lines to an alternate process block is usually dashed.
‍12. Data: Data input or output
‍13. Document: A document
‍14. Multi-document: Multiple documents
‍15. Preparation: A preparation step
‍16. Display: A machine display
‍17. Manual Input: Data or information into a system
‍18. Manual Operation: A process step that isn’t automated

How to Create a Flowchart?

Step 1: Map out major steps

Start with a piece of paper, or a free flow chart creator like Zen Flowchar Next, draw several major blocks that represent the most important steps in your process. Don’t worry about the details for now. Because flow charts are read left to right and top to bottom, start your first node at the top left corner of your workspace.

Step 2: Key in details of your flowchart

Fill in the remaining steps. We recommend working in the natural order of the process. An optional step here is to style your chart with different shapes and color to make it easier to follow.

Step 3: Test your chart

Work through all the steps in your chart to make sure they are clear and exhaustive, and that there is no open-ended node remained.

Step 4: Gather feedback & share

Share a draft of the flowchart and get feedback from the intended users to improve upon it. Flowcharts should be made easily accessible to all parties involved. So make sure you publish your work in the right place. Our online interactive flowchart maker Zen Flowchart has a handy publishing feature, which allows you to publish and share your flowcharts. Any future updates you make to the document will automatically be updated.

Types of Flowchart

From the basic flowchart, we have seen its proliferation into other variations to serve specific functions and industries. Here are some types of flowchart you may come across:

  • Process Flowchart
  • Process Map
  • A Process Flow Diagram
  • Workflow Chart
  • Workflow Diagram

Data Flow Diagram

A type of diagram that represents the flow of data in a process or system.

Swimlane Flowchart

A flowchart with the addition of swimlane component, which helps organize the nodes of a chart into the appropriate party or team. Each lane will only contains the steps involving a single party. For example, for a hiring process that involves multiple teams, a standard flowchart may be reorganized into different lanes involving different teams to better view the division of task and handover points in a process.

EPC Diagram

EPC diagrams, or event-driven process chain diagrams, are used to document or plan business processes. This standard was developed within the framework of Architecture of Integrated Information Systems (ARIS) by August-Wilhelm Scheer.

SDL Diagram

SDL diagrams, or specification and description language diagrams are used to describe specifications of a system. In comparison to UML, SDL diagrams deal with the detailed aspects of a system, whereas UML deals with a more abstract level.

UML activity diagrams / Activity Diagrams

UML is a standardized modeling language used to visualize the design of a system. It is often used in the field of software engineering. You can view full specification here.
