How do I create a task shared by different pools in Bonita Studio?

I'm using Bonita Studio and I would like to create a task which would be shared between two pools and an other shared between two pool lanes.

I'm trying to draw all processes in a web dev company to then optimize them, and a visual support is probably the best way to show the modifications. With this goal in mind I'd need to represent meetings with the different people participating to it.

Am I using the right notation model? If so how do I show these meetings? If not what is a better notation model to show a process with different people working together on different tasks with meetings?

Solution

In BPMN, pools identify processes rather than objects or subjects. You cannot split a single task between two pools.
You also cannot split it between two pool lanes. Actually, lanes have no predefined semantics; they can represent anything you want: companies, people, divisions, etc.

So, I'd propose the following. If you have "Software developer", "Designer", "Product Manager" lanes and want all of them participate in a meeting, add one more lane and name it "All project participants". And put the meeting task there.

I think that this won't violate both syntax and semantics of BPMN.

Although you're using Bonita, I'd advise you to visit http://elearning.bizagi.com for a nice online video course dedicated to BPMN diagrams design. It is based on BizAgi modeler, but 1) this modeler is a freeware and 2) There is One BPMN Standard to rule them all. :)
