Boundary events
Boundary events are attached to tasks or sub-processes to model interruptions or timeouts.
| Event type | Behavior |
|---|---|
| Interrupting timer | Used for manual starts or when the trigger is defined outside the BPMN model. |
| Interrupting error | Indicates the process is triggered by an incoming message. Often used in called processes. |
| Escalation | Indicates the process starts at a specific time or after a delay. Useful for scheduled operations. |
Important: Use boundary events to represent expected
exceptions or alternate flows. Place them visually on the edge of the task they
monitor.
