Which process model notation is also maintained by the Object Management Group apart from UML?

The Business Process Model and Notation (BPMN) is a standardized graphical notation that is specifically designed to model business processes. It is maintained by the Object Management Group (OMG), which is an international technology standards consortium. BPMN provides a flowchart-based representation for specifying business processes in a manner that is understandable to all business stakeholders, including business analysts, technical developers, and business people.

BPMN is widely used because it helps in visualizing business processes in a consistent and standardized format, allowing for greater clarity and communication among stakeholders. Its notation is specifically designed to represent complex process flows, making it an essential tool for business process management and improving overall process efficiency.

While other notations like Flow Charts, Event-driven Process Chains (EPC), and Integrated DEFinition Methods (IDEF) have their own merits, they are not maintained by the Object Management Group, which is a critical point of distinction for BPMN. The fact that BPMN is recognized and maintained by a recognized standardization organization enhances its credibility and encourages its adoption across various industries.
