This case study analysis on Process Modeling by Surveying Project. The term process model is employed in various contexts. For instance, in business practice modeling the organization process model is often referred to as the business practice model. Business practice modeling, often named process modeling, may be the analytical representation or illustration of an organization’s business techniques. Basic objectives are: construct a context diagram to illustrate a system’s interfaces with its environment and identify external and temporal business events for a system. Here also analyze logically group events to create a functional decomposition diagram and create event diagrams. Finally explain on merge event diagrams into a system data flow diagram and draw appropriate primitive data flow diagrams.
