DESCRIPTION (lecture 6)
Jump-Starting Context Diagrams, Data Flow Diagrams, Workflows, and Process Models by Visualizing Material and Data Movement within an Organization
Converting a Rigorous Physical Process Model (RPPM) to a Context-Level Data Flow Diagram (DFD) is a simple but critical step in the early project discussion. An RPPM is a great first-cut diagram that focuses on organizational units and the exchange of material or data. Looking inside an organizational unit to see how they do what they do requires a more detailed perspective. The Context-Level Data Flow Diagram is a phenomenal picture of the scope of a project and sets the stage for drilling down individual processes to get the right requirements for your project.
Lecture 6 answers questions like:
1. What is the difference between a Rigorous Physical Process Model and a Context-Level DFD?
2. How can I convert the RPPM to a legitimate DFD?
3. Why is this conversion necessary?
