At the heart of BPMN lie its core elements, each serving a distinct purpose in illustrating the flow of activities. These elements can be broadly categorized into four main groups: flow objects, connecting objects, swimlanes, and artifacts. Flow objects https://www.cmwlab.com/blog/bpmn-basics-elements-symbols/ are the primary building blocks of a BPMN diagram, representing the activities, events, and gateways that constitute a process. Activities, depicted as rounded rectangles, denote specific tasks or actions performed within the process. Events, represented by circles, signify occurrences that trigger, interrupt, or conclude a process flow. Gateways, illustrated as diamonds, control the flow of the process based on specific conditions or decision points.
