Description A diverging Exclusive Gateway (Decision) is used to create alternative paths within a process flow. This is basically the diversion point in the road for a process. Only one alternative path can be taken for a given instance of the process. A Exclusive Gateway can be thought of as a question that is asked at a particular point in the process. The question has a defined set of alternative answers. Each question is associated with two or more condition expressions associated with outgoing sequence flows of the Gateway. A converging Exclusive Gateway is used to merge alternative paths. All incoming sequence Flows tokens will be routed to the outgoing sequence flow without synchronizing them. | There are two icons defined for an Exclusive Gateway in the BPMN2 Specification.It can be displayed with or without an internal marker. |
