Business Process Modeling Overview:

Business Process Modeling (IDEF0) is the first step in Business Modeling and it is followed by Process Flow Modeling (IDEF3) and Data Flow Diagrams (DFD). In Business Process Modeling, an organization’s functions are represented by using boxes and arrows. Here boxes represent activities and arrows represent the information associated with an activity. Input arrow, Output arrow, Mechanism arrow and Control arrow are the different types of arrows that are used in business process modeling.

The business process modeling is started with a context diagram and it provides a brief overview about the organization’s activity. In order to understand the activities of an organization in a detailed manner, the context diagram is then decomposed into many sub activities diagrams.
