Collaboration and Process Diagrams (BPMN Executable)

A collaboration diagram analyzes the sequence flow of processes and the exchange of messages between participants (represented as swimlanes and pools). Each pool contains an implicit process with a start event and one or more end events. A process diagram analyzes the sequence flow in a single process in a participant (which can be shown or implicit). PowerDesigner supports collaboration diagrams and process diagrams as standard business process diagrams with a BPMN-specific toolbox.
