ITPEC IP April 2025 Question 47
ITPEC IP April 2025 — Question 47 of 100
Clarify the required functions and performance — defining what the system must achieve is the purpose of system requirements definition.
Functional requirements describe services and behavior, while nonfunctional requirements include performance and other quality constraints. Establishing these before detailed architecture and implementation gives later design and testing a clear target.
Answer (c)
Why not others:
- (a) is execution in a production-like environment during later testing
- (b) prepares system integration or system testing
- (d) belongs to implementation and evaluation, not requirements definition
Key rule: Requirements state what and how well the system must do; architecture decides how the system will satisfy those requirements.
