Historical Background of Flow Diagrams
Flow diagrams have a long history, starting in the early 20th century. In 1921, Frank and Lillian Gilbreth created the “flow process chart” for industrial engineering. This idea quickly became popular, and by the early 1930s, instructors taught it in industrial engineering classes.
The 1940s brought a big change with the rise of computer programming. In 1949, Douglas Hartree showed how Herman Goldstine and John von Neumann used flowcharts for computer plans. This was a big step in using decision tree diagramming in computing.
In the 1960s, ANSI standardized flowchart symbols, which ISO adopted in 1970. Today, ISO 5807 is the standard for flowcharts, helping everyone understand process modeling. Flow diagrams have come a long way, from industrial engineering to software development, helping us visualize processes and make decisions for over a century.
Types of Flow Diagrams
Flow diagrams visually represent processes and the movement of information. Industries widely use them to simplify complex systems and optimize workflows.
- Process Flow Diagrams (PFDs): Common in fields like chemical engineering, PFDs provide an overview of processes such as oil refining and water treatment.
- Data Flow Diagrams (DFDs): Popular in software development, DFDs help developers and users understand intricate systems.
- Workflow Diagrams: These focus on streamlining work processes by identifying inefficiencies and bottlenecks.
- Swimlane Flowcharts: Ideal for multi-team projects, swimlanes divide tasks into distinct sections, clarifying responsibilities.
- Business Process Model Notation (BPMN): A standardized tool for mapping business processes.
- Event-Driven Process Chain (EPC) Diagrams: Used for resource planning and improving business processes.
Flow diagrams are invaluable for enhancing efficiency and achieving organizational goals. For instance, one company increased sign-ups by 12% after refining its processes. These tools are essential for businesses pursuing ISO certifications, BPM automation, ERP integration, and compliance improvements.
Key Symbols Used in Flow Diagrams
Flow diagrams use special symbols to show different parts of a process. These symbols are key to visual programming and make complex steps easy to follow.
- Oval (Terminal Symbol): Indicates the start or end of a flowchart.
- Rectangle: Represents a process step or action.
- Diamond: Denotes a decision point where the flow can branch.
- Parallelogram: Shows input or output of data.
- Document Symbol (Sheet of Paper): Represents document generation.
- Cylinder: Depicts database interactions.
- Arrows: Connect symbols, directing the flow of the process.
Using colors can make flow diagrams clearer. It helps show different actions or departments, making it simpler for teams to grasp and improve complex workflows.
Learning these basic symbols is crucial for creating clear process diagrams. It’s useful in many fields. For those in app development, making effective user flows can really improve how users experience your app.

Creating an Effective Flow Diagram
Creating a flow diagram requires careful planning. Start by defining your process. Identify key steps and where decisions occur, putting them in order.
Use the same symbols and clear labels to make it easy to read. The right spacing and alignment are important for understanding.
Many drawing programs require manual spacing adjustments in flowcharts. To make it easier, use specialized software like Lucidchart or Microsoft Visio. These tools have templates and symbols to help you work faster.
Keep your flow diagram simple. Use short texts inside shapes, no more than 3-5 words. Stick to 4 to 5 colors to keep it clear and professional. Most people find left-to-right flow easier to follow.
Consistency in design is crucial for clear visual programming. It helps everyone understand your diagram better.
Collaboration is key when making flow diagrams. Tools like Confluence whiteboards let teams work together live. Once done, you can share the flowchart easily for feedback. This helps improve communication and processes in your team.
Common Mistakes To Avoid
When making flow diagrams, it’s important to avoid common mistakes. One big error is making the diagram too complicated. Keep it simple and focus on the main steps of your process.
Another mistake is using the wrong flowchart symbols. This can confuse people and impede the flow of information.
It’s also a big mistake to ignore who you’re making the diagram for. Make sure the diagram is easy for your audience to understand. Don’t have too many lines crossing over, as it can make the diagram hard to follow.
Use simple language, and keep the diagram short. If possible, it should fit on one page.
Being consistent is crucial when creating flow diagrams. Use the same size symbols and stick to one direction, like top to bottom or left to right. Don’t use too many colors, as it can be distracting. Make sure there’s enough space around symbols for a clean look.
By avoiding these mistakes, you’ll make flow diagrams that are easy to use and understand.
