Chapter Notes

The Business Process Modeling Notation is standardized by the Object Manage-
ment Group [185]. In general, the main purpose of BPMN models is to facilitate
communication between domain analysts and to support decision-making based
on techniques such as cost analysis, scenario analysis, and simulation [43, 202].
However, BPMN models are also used as a basis for specifying software system
requirements.
Alternative notations for modeling business processes include UML Activity
Diagrams [183], Event-driven Process Chains [129], and Business Process Execu-
tion Language [36]. The latter two will be explained in the next two chapters along
with their relation to YAWL.
