ITPEC IP April 2024 Question 94
ITPEC IP April 2024 — Question 94 of 100
A DFD models a system from the viewpoint of how data moves among processes, stores, and external entities. A Data Flow Diagram uses symbols for processes, data flows, data stores, and sources or destinations. Analysts can decompose a high-level diagram into more detailed levels to understand business processing and define system requirements.
Answer (b)
Why not others:
- (a) BPR radically redesigns business processes to achieve major improvements
- (c) MRP calculates material requirements for production
- (d) WBS hierarchically decomposes project deliverables and work
Key rule: DFD follows data through processing; WBS follows project work, while BPR and MRP are management methods rather than data-flow modeling notations.
