Once you have modeled your business process on the diagram pane, you can add execution parts to this process to bring it to life. The execution pane is the place where you make your model executable.

The execution pane is displayed below the diagram pane. It is shown as soon as you click on one of the BPMN elements:

Designer > Modeling Execution > execution_canvas.png

Creating an Execution Model

The content of the execution pane depends on the BPMN element. For some elements the execution model must be created manually when you want to add execution, for others a default execution diagram is created automatically. Some BPMN elements allow for no execution at all.
