Definition

A point in the workflow where two or more parallel executing activities converge into a single common thread of control.

Key Points

The execution of parallel activities commences with an AND-Split and concludes with an AND-Join. For example, in a credit application process there may be a split in the workflow at which point multiple activities are completed separately (in parallel, if not simultaneously.) Each parallel executing thread is held until the set of all thread transitions to the next activity is completed at which point the threads converge and the next activity is initiated.
