• Activity diagrams provide an ability to clarify which actor performs which activity.
• A swimlane diagram (also sometime called a cross-functional diagram) documents the steps or activities of a process flow or workflow.
• More specifically, a swimlane diagram groups these activities into swimlanes which are horizontal or vertical columns that contain all of the activities which fit into the category represented by that swimlane.
• Swimlanes can represent many categories of information such as actors which perform the activities (i.e., role or department), the stage of the process in which the activity takes place, or whatever else the creator of the document feels should be emphasized and communicated by the swimlane diagram.
• The term swimlane was adopted due to the visual similarity between the horizontal rows of the diagram to that of theswimlanes found within a swiming pool.
