What does a lane in a swim lane diagram refer to?

A lane in a swim lane diagram represents performers or combinations of performers who are responsible for specific tasks within a process. This visual format helps delineate who is accountable for each step and provides clarity on roles and responsibilities across different stages of a workflow.

By using lanes, it becomes easier to see how different individuals, teams, or departments interact within a process. This clear demarcation allows stakeholders to quickly identify where delays or issues may arise, as each lane highlights the contributions and dependencies of the performers involved. The diagram effectively showcases the flow of tasks and responsibilities, making it a valuable tool for process analysis and improvement.
