In step b, the activity is executed by the one of the plurality of activity servers. In step c, a next activity to be performed is determined based on workflow transition information. In step d, the next activity is executed if the one of the plurality of activity performs the next activity. In step e, the next activity is forwarded to the workflow queue if the one of the plurality of activities does not perform the activity. Steps a-e are repeated until all of the plurality of activities in the workflow are executed.
