Furthermore, swimlane is used for partitioning actions based on the participants involved. The activities are initiated at the initial node and are terminated at the final node. It supports flow branches via the decision elements and the merge elements and parallel execution using forks. customer (the XP term for stakeholder) to analyze a user Each and every activity, condition, and association must be recognized. by courses of action within a use case.
