Rule
Object: Represents operators used for specifying the logical connections of events and activities in models of the Business process and BPMN Collaboration Diagram (2.0 Beta) types.
In models of the BPMN diagram type, the Gateway object serves as an operator.
In models of the Business process type, the following rules with these meanings exist:
AND rule
All processing steps for incoming connections must be completed so that the processing steps that follow the rule can be performed. If, e.g., two particular persons are required to perform an activity, the activity can only be performed when these two persons have completed the activities of other processing steps. Only then are they both free to perform the pending activity together.
OR rule
At least one processing step (or even several or all processing steps) must be completed, whereupon the processing steps that follow the rule can be performed. If, e.g., any two persons are required to perform an activity, the activity can be performed when two or more people are free after completing previous processing steps. It does not matter which two persons this is.
XOR rule (exclusive OR)
Only one of the processing steps for incoming connections may be completed so that the processing steps that follow the rule can be performed. This is the case for situations, e.g., in which only alternative results are possible. Checking goods received can, for example, either result in the events "Fault found" or "No fault found".
Available attributes
Note
In models of the Reduced BPMN diagram (ARISalign-compatible) type only the attributes Name and Description/Definition can be specified.
