When a decision activity is executed, the workflow engine creates the associated task. A snapshot of the workflow data object data required for the decision activity subject and action text parameters, and any secondary action message text and link parameters, is taken and stored. The allocation strategy associated with the decision activity is invoked to determine the user(s) who will be assigned the decision task. The workflow engine also creates an event wait for the DECISION.MADE event with the associated task identifier as the event match data. The workflow is then paused at this point, awaiting the raising of this event which will indicate the result of the decision made.
