CMMN is a relatively new notation that was created to account for more flexibility in the business process landscape.

This notation is designed for scenarios when a case worker can decide in what order tasks or sequence flows should be performed. A CMMN sequence flow may be triggered by an event (Event Listener), a state (Milestone) or with an action (Task).

As CMMN can be seamlessly integrated into BPMN and DMN-diagrams, you can use it to complement your existing process landscape. CMMN provides you with the possibility of depicting highly variable processes, such as working with patient files or managing customer support processes more accurately.

Signavio supports CMMN version 1.1.
