ITPEC IP April 2024 Question 52
ITPEC IP April 2024 — Question 52 of 100
The waterfall model divides development into ordered stages, with each later stage based on the output of the preceding stage. A typical sequence is requirements, design, programming, testing, and installation. The model emphasizes completing and documenting one stage before proceeding, which makes progress and deliverables easy to manage when requirements are stable.
Answer (c)
Why not others:
- (a) describes iterative refinement between design and implementation
- (b) describes incremental or iterative development that repeatedly responds to user requests
- (d) describes prototyping, where an early model is used to clarify requirements through feedback
Key rule: Waterfall proceeds stage by stage using approved upstream outputs; iterative and prototype models deliberately use repeated feedback cycles.
