What is a key benefit of using a swimlane diagram in process design?

• A. It visualizes tasks and handoffs across roles/teams
• B. It forecasts demand
• C. It details financial risks
• D. It measures product quality

Answer: (A)

Swimlane diagrams are designed to map a process across the people or teams that perform its steps. By dividing the diagram into lanes for each role, it makes who is responsible for each task and when transitions between tasks occur visible in one view. This clarity helps designers spot gaps, duplicate work, or bottlenecks that slow handoffs, and it supports coordinating cross-functional work to improve the overall flow. Although forecasting demand, assessing financial risks, or measuring product quality are important on their own, the strength of a swimlane diagram lies in showing the sequence of activities and how handoffs happen between roles, so accountability and collaboration are easier to manage.
