What is a Flowchart?

Flowcharts are essential tools for visualizing processes, documenting workflows, and communicating complex systems. Whether you're mapping business processes, planning algorithms, or documenting user journeys, flowcharts make abstract concepts concrete and understandable.

Common Flowchart Symbols

• Oval (Terminator): Represents the start or end of a process
• Rectangle (Process): Shows an action or operation
• Diamond (Decision): Indicates a yes/no or true/false decision point
• Parallelogram (Input/Output): Represents data entering or leaving the system
• Arrow: Shows the direction of flow between steps

When to Use Flowcharts

• Documenting business processes and SOPs
• Planning software algorithms and logic
• Mapping user journeys and experiences
• Troubleshooting and decision trees
• Training and onboarding materials
• Project planning and workflow optimization
