Process instance owners can edit the process instances that they own while the process instances are running.
By default, the owner of the process definition is the owner of the process instances that are created from the process definition. However, you can assign process instance ownership to another Role.
To assign process instance owners:
Click the empty space in the Process Definition Editor to display the Properties view for the process definition.
Select the General tab in the Properties view.
Type the name of the Role in the Owner field in the Process Instance Owner area. This will assign the process instance to the owner.
