ITPEC IP April 2019 Question 46
The system development process includes system requirements definition, system design, programming, test, and software acceptance. When a new system is developed, which of the following is defined as a system requirement in the initial stage of development?
Explanation
Scope of the system — at the start of development, system requirements definition fixes what the system will cover before anything is designed.
System requirements definition turns the business needs into requirements for the system: which business operations and users it covers, the functions it must provide, and its performance and other non-functional requirements. The scope is the boundary everything later builds on: design decides how to implement it, and testing checks the result against it.
Answer (c)
Why not others:
- •(a) Device configuration — how the hardware is arranged is decided in system design, after the requirements are fixed
- •(b) Development standard — rules for how the developers work (coding conventions, document formats); it governs the development, not what the system must do
- •(d) Test plan — prepared from the requirements and the design; testing comes later in the listed process
Key rule: Requirements definition answers "what, and how far"; design answers "how", and tests check the result against the requirements.
