Scenario Writer

Describe use-case scenarios step by step – actors, main flow and alternative flows – and export them to JSON, TXT or PlantUML

🎭 Actors

No actors yet. Add at least one actor before adding steps.

How to use

  1. Add the actors (users, systems, subsystems) taking part in the scenario.
  2. Add the main-scenario steps in order; leave the receiver empty for an internal event of the sender.
  3. Use “+ Ext” to describe an alternative or exception flow branching off a step (e.g. 3a, 3b).
  4. Export to JSON to save your work (the scenario is not stored in the browser) and import it later, or export to PlantUML to render a sequence diagram.
