10.5 Events

An Event is something that “happens” during the course of a Process. These Events affect the flow of the Process and usually have a cause or an impact and in general require or allow for a reaction. The term “event” is general enough to cover many things in a Process. The start of an Activity, the end of an Activity, the change of state of a document, a Message that arrives, etc., all could be considered Events.

Events allow for the description of “event-driven” Processes. In these Processes, there are three main types of

Events:

1.Start Events (see page 237), which indicate where a Process will start.

2.End Events (see page 245), which indicate where a path of a Process will end.

3.Intermediate Events (see page 248), which indicate where something happens somewhere between the start and end of a Process.
