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. For a given instance of the Process, only one of the paths can be taken.
A Decision 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 answer is associated with a condition Expression that is associated with a Gateway’s
outgoing Sequence Flows.
