Activity Diagram

Activity diagrams are used to model the behaviors of a system, and the way in which these behaviors are related in an overall flow of the system.

The logical paths a process follows, based on various conditions, concurrent processing, data access, interruptions and other logical path distinctions, are all used to construct a process, system or procedure.

Note:

You can create Analysis diagrams (Simplified Activity), containing the elements most useful for business process modeling, using the New Diagram dialog.
