Business Process Modelling and Notation (BPMN) is an official standard for representing business processes in a graphical notation. It is a widely used notation for describing and documenting business processes, as well as for designing and implementing automated business processes. BPMN is a visual language for specifying business processes in a graphical form. It is designed to provide a common language for business process modeling, enabling business analysts, process designers, and IT professionals to understand the process in a common way. BPMN is a graphical representation of a business process, consisting of activities, events, gateways, and flows. It is a standardized notation that can be used to represent a wide variety of business processes, from simple to complex. BPMN allows for the definition of business processes in a standard, consistent, and easily understandable manner. This helps to ensure that the process is correctly understood and implemented, as well as providing a common language for communication between stakeholders. BPMN also provides a framework for the automation of business processes, allowing for the integration of existing systems and the creation of new ones.
