A reference model is a generic conceptual model that formalizes recommended practices for a certain domain. Today, the SAP reference models are among the most comprehensive reference models, including over 4000 entity types and covering over 1000 business processes and inter-organizational scenarios. The SAP reference models use Event-driven Process Chains (EPCs) to model these processes and scenarios. Like other informal languages, EPCs are intended to support the transition from a business model to an executable model. For this reason, researchers have tried to formalize the semantics of EPCs.
