ITPEC IP October 2023 Question 46
ITPEC IP October 2023 — Question 46 of 100
Requirements are refined from business requirements to system requirements and then to software requirements. Business requirements express organizational objectives and needed business capabilities. System requirements translate them into behavior and qualities of the overall system, including people, hardware, software, and operations. Software requirements then specify the portion the software must implement.
Answer (a)
Why not others:
- (b) defines software details before the enclosing system requirements
- (c) places business objectives after system requirements, reversing the needed derivation
- (d) begins with system and software details before identifying business needs
Key rule: Move from why the business needs change, to what the whole system must do, to what the software component must do.
