What is a swimlane diagram used for?

• A. A process map that shows tasks and handoffs across roles/teams, useful for visualizing workflows.
• B. A diagram that shows product pricing over time.
• C. A data flow diagram that shows database tables.
• D. A chart that displays revenue projections.

Answer: (B)

Swimlane diagrams map a process across lanes representing different roles or teams, making tasks, sequence, and handoffs visible. By placing each step in the lane of the person or group responsible and drawing arrows between steps, you can clearly see who does what, when it happens, and how work moves from one area to another. This helps identify bottlenecks, delays, and miscommunications in cross‑functional workflows.

In this context, the option that describes showing tasks and handoffs across roles or teams to visualize the workflow is the best fit. The other descriptions refer to different kinds of diagrams—pricing over time, data movement between data stores, and revenue projections—which are not about mapping a cross‑functional process flow.
