Assignment 

As a systems analyst or knowledgeable end-user, you must learn how to draw data flow diagrams to model business process requirements. The preliminary investigation and problem analysis phases of the methodology have been completed and you understand the current system’s strengths, weaknesses, limitations, problems, opportunities, and constraints. You have already built the Context models (Milestone 3) to document business requirements for the new system. You now need to build the Level 0 (System) DFD and corresponding process models. 

Activities 

1. Develop Level 0 DFD. Make      assumptions where necessary. 
2. Draw one Child Diagram      using the Level 0 diagram.
3. Continue decomposition of      one process up to primitive processes (Level 2, Level 3, etc.)

Deliverable format and software to be used are according to your instructor’s specifications. Deliverables should be neatly packaged in a binder, separated with a tab divider labeled “Milestone 5-Part II”.
