ITPEC IP October 2025 Question 46
In the process of system requirements definition, which of the following is the appropriate evaluation criteria for system requirements?
Explanation
Consistency with needs of the customer — system requirements are evaluated against the needs of the party that orders the system.
System requirements restate the customer's (acquirer's) needs as requirements for the system. So the criteria for evaluating them in requirements definition are traceability to and consistency with those needs, testability, and the feasibility of designing, operating and maintaining the system.
Answer (b)
Why not others:
- •(a) — the results of the system integration test do not exist yet during requirements definition; the test is later checked against the requirements, not the other way round
- •(c) — whether the design method is appropriate is evaluated in the design phase
- •(d) — test case coverage is evaluated when the tests are designed and run
Key rule: Each phase is evaluated against its input: requirements against the customer's needs, design against the requirements, tests against the design and requirements.
