Event-driven process chain

The event-driven process chain method was developed within the framework of Architecture of Integrated Information Systems (ARIS) by August-Wilhelm Scheer at the Institut für Wirtschaftsinformatik, Universität des Saarlandes (Institute for Business Information Systems at the University of Saarland) in the early 1990s.

The event-driven process chain method was developed within the framework of Architecture of Integrated Information Systems (ARIS).

Several scientific articles are devoted to providing well-defined execution semantics for general event-driven process chains.

These elements are used in event-driven process chain diagrams: As shown in the example, a customer order received is the initial event which creates a requirement capture within the company.

Although a real process may include a series of stages until it is finished eventually, the main activities remain similar.
