ITPEC IP April 2022 Question 49
ITPEC IP April 2022 — Question 49 of 100
Clarifying required outputs and target processing time is system requirements definition. The financial statements describe functional requirements—what the system must produce—while the required processing time is a nonfunctional performance requirement. Meetings with the customer establish and agree on these system-level needs before detailed design and implementation.
Answer (b)
Why not others:
- system testing checks the completed system after development
- software detailed design defines the internal logic of software components
- software architecture design determines the high-level software structure after requirements are understood
Key rule: Requirements definition establishes what the system must do and its quality constraints; design determines how software will satisfy them.
