Project Manager Shows the action states that are the responsibility of a project manager. The swimlane makes it obvious that the project manager is responsible for entering data, thus the rather cumbersome action state name of
ProjectManagerEntersDatamay be shortened toEnterData.-
Project Management System Shows the action states that are the responsibility of the project management system. Again, because the swimlane makes it obvious who (or what, in this case) is generating information, the rather cumbersome action state name of
