In a business process model, what element typically represents the start or end of a process?

In a business process model, the element that typically represents the start or end of a process is a circle. This symbol is conventionally used in various modeling notations, such as Business Process Model and Notation (BPMN), to designate the boundary points of a process. The use of a circle provides a clear visual cue that signifies the initiation or conclusion of the workflow, making it easy for stakeholders to understand the flow of activities. Understanding these symbols is essential for accurately interpreting and communicating business processes, enabling better analysis and decision-making.
