Before creating this diagram, the Operational Process diagram must be created first.

To create an Operational Process Flow diagram for Operational Activity flows

1. Do one of the following:
   • Create a Swimlane and assign Operational Performer or Operational Role.
   • Drag the Operational Performer or Operational Role from the Containment tree directly to the diagram pane to create the Swimlane.
2. Create Operational Activity Actions or just drop Operational Activities from the Containment tree directly to the diagram pane.
3. Connect Operational Activity Actions with Operational Control Flow or Operational Object Flow.
4. Display the possible Operational Exchanges on Operational Control Flow or Operational Object Flow.

When the Operational Activity Action is created in the Swimlane, the IsCapableToPerform relationship is created between the Operational Performer and Operational Activity (the behavior of the Operational Action). Furthermore, if the Operational Role is assigned to the Swimlane, the PerformInContext relationship is created between the role and Operational Activity Action.
