The 4 steps for drawing a Swimlane

Описание: Swimlane
 
A swimlane diagram is an extension of the basic Flowchart. Extra information is connected with the activities from a flowchart about:
● Roles
● Departments
● Sub processes
The Swimlane is represented visually with horizontal or vertical ¨lanes¨.
 
The metaphor of Swimlane in the swimming-pool is used to make it clear who is responsible for what, by aligning the steps of a process into the horizontal or vertical ¨swimlanes¨.
