ITPEC IP April 2023 — Question 50 of 100

In the waterfall model, each development phase is completed before the project proceeds to the next phase. Work flows sequentially through requirements, design, implementation, testing, and deployment, with defined deliverables and reviews at phase boundaries. The model works best when requirements are sufficiently stable and changes can be controlled.

Answer (a)

Why not others:
- (b) describes rapid application development using tools, reusable parts, and divided functions

- (c) describes prototyping to clarify requirements with an early working sample

- (d) describes iterative or incremental development that repeatedly incorporates feedback

Key rule: Waterfall is phase-oriented and sequential; prototyping and iterative models deliberately seek earlier feedback through repeated cycles.
