Question

When using pools in a bpmn activity model, which of the following is not required?

multiple choice
A. sequence flow must be continuous from start to end
B. each pool needs a start event
C. each pool must have multiple lanes
D. each pool needs one or more end events

Answer 1

In a BPMN activity model, it is not required for each pool to have multiple lanes; however, continuous sequence flow, a start event, and one or more end events per pool are necessary.

Step-by-step explanation:

When using pools in a BPMN (Business Process Model and Notation) activity model, each pool does not need to have multiple lanes. This means that option C, 'each pool must have multiple lanes,' is not required. A pool represents a participant in a process and can contain multiple lanes, but it is not obligatory to have more than one lane within a pool.

It is essential, however, for the sequence flow to be continuous from start to end (option A), for each pool to have a start event (option B), and for each pool to need one or more end events (option D) to ensure the process is complete and that there is clarity in the starting and ending points of the process.
