The parallel gateways are points in the process where multiple parallel paths are defined and they are also used to synchronize (wait for) parallel paths.
Parallel gateways represent concurrent tasks in business flows, and a fork gateway is always accompanied by a join gateway, where a fork gateway illustrates concurrent flows and expresses the fact that all outgoing paths must be pursued. On the other hand, a join synchronization gateway mandates that all the concurrent paths must be completed ahead of process advancement to subsequent tasks/activities.
