ITPEC IP October 2025 Question 98
When the system life cycle is divided into the planning process, requirements definition process, development process, and operation/maintenance process, which of the following is the appropriate process to clarify the functions of the system for the implementation of business operations?
Explanation
Requirements definition process — it clarifies the functions the system needs to carry out the business.
In the requirements definition process, the business requirements are turned into system requirements: the functions the system must provide (functional requirements) and qualities such as performance and security (non-functional requirements), agreed between the users and the developers.
Answer (b)
Why not others:
- •(a) — the planning process decides the purpose, scope, investment and overall plan of computerization, not the detailed functions
- •(c) — the development process designs, builds and tests the system to meet the requirements already defined
- •(d) — the operation/maintenance process runs the finished system and makes changes to it
Key rule: Planning decides why and what to computerize; requirements definition decides what the system must do; development decides how.
