In the Example University BPMN scenario, how would pools and lanes be used?

• A. A pool would be used to represent a process for Example University. Lanes would be used to represent processes for students, the Registrar's office, and professors.
• B. A lane would be used to represent a process for Example University. Pools would be used to represent processes for students, the Registrar's office, and professors.
• C. No pools would be used. Only lanes would be used to represent participants.
• D. Pools and lanes are interchangeable.

Answer: (B)

In BPMN, a pool defines a participant or a process boundary in a collaboration, while lanes are used inside a pool to divide work by role or department. For the Example University scenario, modeling the university’s overall workflow as a single pool and creating separate lanes for the actors—students, the Registrar's office, and professors—clearly shows who performs which tasks and where handoffs happen within the same overarching process. This arrangement keeps the cross-participant interactions visible in one scope and matches how lanes are used to allocate responsibilities within a single process boundary. The alternative of flipping this mapping would mix the main process boundary with participants in a way that can obscure handoffs, and statements claiming no pools or that pools and lanes are interchangeable contradict how BPMN is typically structured.
