ITPEC IP October 2019 Question 47
ITPEC IP October 2019 — Question 47 of 100
Requirements progress from business requirements to system requirements and then to software requirements. Business needs and desired operations establish the purpose; system requirements define the overall solution; software requirements refine the behavior required of software components.
Answer (a)
Why not others:
- software requirements cannot sensibly precede the broader system requirements from which they are derived
- system requirements should not precede understanding the business problem and objectives
Key rule: Requirements are refined from business intent to the whole system and finally to detailed software capabilities and constraints.
