Lane

Intro

A Lane is a partition used to organize activities in a swim-lane process diagram. In BPMN, lanes sit within a Pool in Collaboration diagrams.

Key points:

  • Clarifies roles, systems, or departments in a process.
  • Improves accountability and handoff visibility.
  • Common use cases across EA/BPM/Data/App/Tech include modeling internal roles, enterprise applications, or functional units.
  • Pitfall: overusing lanes, creating clutter and hard-to-read diagrams.

Examples:

  • Manager and Associate lanes show approval responsibilities.
  • System lane representing an ERP for automated steps.
  • Finance and Shipping lanes for cross-functional workflows.

In practice:

Use lanes sparingly to highlight accountability; map handoffs clearly between lanes.
