Which process model notation is maintained by the Object Management Group?

The correct answer is Business Process Model and Notation (BPMN). BPMN is a standardized method for representing business processes, designed to provide a common language for all stakeholders, including business analysts, technical developers, and business process participants. It was developed to provide a graphical notation that is understandable by all business users while also being capable of being mapped to the underlying technologies used for implementation.

BPMN is managed and maintained by the Object Management Group (OMG), which is an international technology standards consortium. The OMG plays a significant role in the evolution and endorsement of BPMN as a leading modeling notation in business process management. This governance ensures that BPMN remains relevant and widely adopted, aligning with the needs of the industry.

In contrast, while Unified Modeling Language (UML) is also a standard managed by OMG, it is primarily focused on software engineering and system design, rather than specifically on business process modeling. Other notations like Integrated DEFinition Methods (IDEF) and Event-driven process chain (EPC) are not maintained by OMG and serve different historical and application-specific contexts in process modeling.
