Event-driven Process Chain - Meta-model of EPC

Meta-model of EPC

Although a real process may include a series of stages until it is finished eventually, the main activities remain similar. An event triggers one function; and a function will lead to one event. Meanwhile, an event may involve one or more processes to fulfill but a process is unique for one event, the same goes for Process and Process Path. As for the function, its data may be included in one or more information resources, while Organization Unit is only responsible for one specific function.
