Collaborative Activities Inside Pools

Choreographies and Conversations, introduced with BPMN 2.0, will make modellers able to describe interactions among different Participants as well as messages exchange. Often enough different Participants have to accomplish the same task. This can be now easily and clearly represented using BPMN 2.0. BPMN 2.0 does not specify the usage of Lanes neither their meaning. However, Lanes are sometimes used to specify internal roles or departments. In this context it could happen that modellers want to represent an Activity performed by different roles or offices together (e.g., to attend the same meeting, collaborative writing of a document). Such situation has been modelled so far by using merging Gateways placed before the activities, but this patch does not solve a related problem. BPMN forces to draw elements within Lanes boundaries. This means that, at least conceptually, one activity is leaded by the subject which the containing Lane is linked to, which is not necessarily true. Some experiments revealed how much a mean to model such inner collaboration is a desirable feature. In this paper the problem analysis, results and some proposals on how to extend BPMN will be presented.
