Success with BPMN 2.0 – Flexibility through Public Processes
If process parts are loosely coupled, then it is possible to discern between a Public Process and a Private Process. A Public Process contains all process parts and dependencies of the process of a Participant, that are relevant for the interaction to the other Participant. For example in a buyer – seller relationship it is not relevant if the seller has an internal approval process of of what form it is. It is only relevant if the order request is to be confirmed or not and in which time.
Therefore designing public processes gives flexibility within Participants to change processes as necessary – often without or with reduced side effects to the interation to the other Participant. This reduces cost in Process adaptations.
