I keep receiving an error during a semantic check of my BPMN model against one of my end events that "this object type 'End event' violates the following rule: 'If a process uses an object type 'End' event, at least one object of type 'Start' event is required'"

My process map has a start event that is in one pool and the errors are against the end events in another pool. Do you need a start event in each pool? Pasted below

Hello,

your image was not pasted.

A pool delimits a process in a BPMN Collaboration diagram. So everything inside the Pool is part of the process, everything outside the Pool is the rest of the world (other Pools) the process "collaborates" with through message flows. So if you have multiple Pools in a single diagram and each Pool is "white box", i. e. has modelled content, each Pool needs to obey the BPMN rules for processes.

See chapter 9.3 on Pools and chapter 10.5.2 on the start event in the BPMN 2.0 specification.

I would recommend to use only one white box Pool per Collaboration diagram. Name the diagram the same as the white box pool and assign it to the pool.

This is a good response and the recommendation makes sense as I've never been able to find an answer to a collaboration diagram question I have .... if BPMN Collaboration pools are named after participants and each pool represents an ‘implicit’ process. What is the best practise for naming the collaboration model itself … if each pool contains its own process? … and where is the implicit pool process name captured? (Where process flows shown in each pool – white pool … not one process flow pool + black box pools). .... I may post and create a separate thread on the question.

Thank you that is really helpful. I've read the sections you recommended and it makes sense.
