Working Around not Having Complex Gateway by Jan Kettenis
Blog: PaaS Community
In this article I describe how you can work around not having the Complex Gateway in OIC Structured Process. I will end with what I believe to be the best work around with respect to support for refactoring.
The Complex Gateway in BPMN 2.0 is one of the least used features of BPMN. However, when you find a use case for it also may find that there is no alternative way to model it, or not an easy one. The challenge being that in case of parallel flows (be it via Parallel or Inclusive Gateway) the token must move to the merge gateway for each individual flow before it can move further.
One typical use case that I have ran into a couple of times is the one where at a specific point in the process there is more than one way to do something, and either one of them might happen after which the process can move on to the next activity. In case there are only two ways, most of the times you can model this by adding an interrupting Boundary Message or Timer Catch event to the activities. Read the complete article here.
