Choreography Diagram Basics

You create a choreography diagram for any decomposed process for ebXML and BPEL languages, and at any level of the process hierarchy for other languages. Each choreography diagram contains a control flow, which organizes the sub-processes directly below the process from which the diagram has been created.

The choreography diagram is the core BPM diagram, which lets you perform the following tasks:

• Allocating Responsibilities
  You can use a choreography diagram to analyze how processes modeled in the system will be allocated to people, groups or organizations. These resources are modeled as organization units and are represented in the choreography diagram as swimlanes.
• Tracing the Process Choreography
  A choreography diagram describes the control flow of a process by showing a path from one or more starts through a sequence of sub-processes, decisions, synchronizations, and resources to one or more ends. The placement of a process in a swimlane or another shows which organization unit is responsible for it. The parent process being analyzed in the diagram must wait for the end of all its sub-processes before it terminates.
• Analyzing Data
  The choreography diagram provides various ways to model the flow of data in the system.
• Modeling the Implementation of Processes
  The choreography diagram provides various ways to model the implementation of processes in a system.
• Choreography Diagram Objects
  PowerDesigner supports all the objects necessary to build choreography diagrams.
