What you can model
Swimlane diagrams show process steps by role or system. Cross-team processes fail when handoffs are invisible. Lanes make who acts at each step obvious.
How to use this maker
Define a lane per role or system, place actions in order, preview handoffs, then export PNG or SVG for operations docs.
Notation that matters
Each lane is a responsibility boundary. Actions sit in the lane of the actor who performs them. Handoffs appear when the flow crosses lanes. Keep lane names stable across related diagrams.
Keep the diagram readable
Use a plain flowchart when ownership is not the question. Use an activity diagram when you want stronger UML framing without stressing lanes. Avoid more lanes than readers can scan on one screen.
