Start Event

Start Event

Intro

A Start Event marks the beginning of a BPMN process. It triggers the normal flow based on conditions like messages, timers, or signals.

Key points:

  • Defines the entry point and trigger type.
  • Improves clarity and execution control.
  • Common use cases across EA/BPM/Data/App/Tech include timer‑based schedules, message‑driven starts, and user‑initiated processes.
  • Pitfall: ambiguous starts that cause inconsistent behavior.

Examples:

  • Timer start launching nightly batch processes.
  • Message start for incoming customer orders.
  • User start when a request form is submitted.

In practice:

Choose the specific start event type to reflect triggers and compliance needs in execution.
