What are the types of BPMN diagrams?

Last updated on February 21, 2023

BPMN diagrams can represent simple or complex processes, both internal and external. Here are some of the different types of diagrams:

  • Collaboration diagrams: These show the interactions between two or more processes, using more than one pool. Each pool focuses on the work performed, and messages can be passed between them.
  • Choreography diagrams: These show the interactions between two or more participants. They can be contained within a collaboration diagram, adding tasks and sequences that establish how the participants interact.
  • Conversation diagrams: These are a simplified version of a collaboration diagram, showing a group of related message exchanges in a business process.

Each of these types of diagrams offers a different level of detail and perspective on a business process, and selecting the appropriate diagram type depends on the goals of the process modeling.
