It is hard to find a serious BPMN model without any splits in the control flow. Splits are modeled with gateways, represented by diamond symbols. The following video shows three variations of a little example process. First, we use an exclusive gateway in this process, then a parallel gateway, and finally an inclusive gateway. The execution of each process variant shows the different behaviours of the three gateway types.
If you want to try out these examples for yourself, you can download and execute them, using the community edition of the „Bonita“ platform.
