    When to use a process flow diagram

    PFDs are ideal for documenting onboarding, approval workflows, manufacturing steps, software request handling, and customer journeys. For looser brainstorming use the whiteboard; for radial idea structures use a mind map.

    Build your first PFD

    1. Open the expense approval template.
    2. Place a circle for the start node.
    3. Add rectangles for each process step and diamonds for decisions.
    4. Use the Connect tool to wire steps with arrows.
    5. Export as PNG or SVG to drop into docs or slides.
