requirements during systems analysis‚ we should model technology architecture and requirements during systems design. The models serve as blueprints for system design‚ prototyping and construction. In this milestone you will prepare a Physical Data Flow Diagram. Physical data flow diagrams model the technical and human design decisions to be implemented as part of an information system. They communicate technical and other design constraints to those who will actually implement the system—in other words
