Once you have exploded a process on your data flow diagram to a lower level of detail, you need to balance the two levels to ensure completeness and avoid missing pieces early in the project when it is still cheap to add them. Waiting until later in the process to discover them has proven to […]
Learn about Data Flow Diagrams (DFD) and Rigorous Physical Process Models (RPPM), what they are, why they are important, and who can use them. The book presents a simple, easy-to-learn approach for creating these diagrams from an interview with a Subject Matter Expert (SME). You will learn when, why, and how to create a context […]
Exploding or levelling a process on a Data Flow Diagram is a revealing exercise for the one wearing the BA hat AND for the subject matter experts that live the process. It is a critical technique for anyone who wants to analyze an existing situation, define the requirements for improvements, and understand the consequences of […]
Levelling or exploding a process on a DFD reveals the internal details of how the process works and sets the stage for process analysis for requirements discovery. Identifying the internal processes is a critical first step to exploding a process. The post Identifying Internal Processes for a DFD appeared first on BA-EXPERTS.
A simple Rigorous Physical Process Model is a fantastic tool for initiating a discussion about a potential project. Converting an RPPM to a Context-Level Data Flow Diagram (DFD) is also a simple but critical step in the early project discussion. The post From Rigorous Physical Process Model to Context-Level DFD appeared first on BA-EXPERTS.
