Business process modeling is a collection or group of related activities or business processes that produce a specific service or product. Business processes are visually represented as diagrams of simple box with arrow graphics and text labels, better known as Business Process Models.
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.
Business Process Modeling Diagram:
Similarly decomposition of context diagram is done in process flow modeling and data flow diagrams. Context diagram is similar to a conceptual data model in data modeling. The following example gives the layout of the context diagram.
