A swimlane diagram is a type of flowchart that delineates who does what in a process. Using the metaphor of lanes in a pool, a swimlane diagram provides clarity and accountability by placing process steps within the horizontal or vertical “swimlanes” of a particular employee, work group or department.

A swimlane diagram is a cross-functional flowchart. It shows who does what at each step in a workflow. Like lanes in a swimming pool, swimlanes (a.k.a. functional bands) separate activities from start to finish. In this case, it shows the division of roles, responsibilities, and sub-processes among different departments, people, and work groups.

A swimlane diagram is a graphical representation of who does what and when in a process. A swimlane diagram uses the metaphor of lanes in a pool that extend horizontally or vertically to indicate ownership of workflow tasks. Swimlane diagrams can uncover duplicated efforts, redundancies, inefficiencies, and bottlenecks.

A swimlane diagram is a flowchart that illustrates a chronological process from start to finish. These steps are presented using standard shapes connected by arrows. The diagram is divided into lanes representing departments or personnel, showing who does what in a workflow.
