For modeling inter-participant processing BPMN provides a rich framework, which includes:

  • swim lanes
  • message flow
  • message events
  • send and receive tasks
  • message correlation

Example of participation exchange and pools / swim lanes

The diagram above was created in MS Visio, using a stencil I created for sequential flow and other stencils containing the notation used in Events, Sequential Flow and Activities – altogether, this makes it easier to draft models in Visio. The original notation I used in my participant exchange stencil were sourced from some good guys at bpmresearch and I refined them a little for my own purpose. In the spirit of open source (!) I also provide my stencil here for BPMN Participant Exchange, (simply save the zip file to your desktop, unzip the file and copy the BPMN Participant Exchange.vss file to your My Shapes folder – then, open MS Visio and go to File > Shapes > Open stencil… Select BPMN Participant Exchange.vss and open it. Voila!)
