This is a main process BPMN notation. Process diagrams are used to represent the sequence of steps in a process. Process modeling defines how practices should be carried out and formalizes them. Participants in a process, activity sequences, information transferred during a process, and trigger events are represented in flow diagrams. Processes can also describe the various controls, decisions, and coordinations that take place inside a series of tasks. EdrawMax is the perfect tool to draw a process flow diagram.
