Lane

A Lane is a sub-partition within a process (often within a pool) and will extend the entire length of the process level, either vertically or horizontally. Lanes are a good way to organize responsibilities in a process. Often, a pool defines a process or an organization and the lanes represent departments. BPMN elements such as Tasks, Gateways etc. are then modeled within the pool that most matches that organizational unit. While this has no effect on most tasks, User Tasks can benefit from it.
