Events in BPMN

Events represent something that happens during a process. Events can start, interrupt, delay, or end the process flow. In BPMN, each event is defined by its type (start, intermediate, end) and trigger (e.g., message, timer, error). This page describes how events should be modeled in Maestro diagrams, independent of execution support.

Modeling recommendations

  • Prefer descriptive labeling on all events to indicate business meaning (e.g., Timeout after 2 days instead of Timer).
  • Use signal events only for loose coordination; avoid using them to enforce logic.
  • For large diagrams, use link events to avoid clutter caused by long flows.
  • Do not overuse intermediate events. Focus on clarity over completeness.
