ITPEC IP April 2019 Question 50
ITPEC IP April 2019 — Question 50 of 100
In the waterfall model, work proceeds through defined phases and moves to the next phase after the current phase is completed. Requirements, design, implementation, and testing form a mainly sequential flow with formal outputs and reviews at phase boundaries.
Answer (a)
Why not others:
- (b) describes rapid development using tools and reusable components, characteristic of RAD
- (c) explicitly describes the prototyping model
- (d) describes iterative or incremental development that repeatedly incorporates feedback
Key rule: Waterfall is phase-oriented and sequential; prototyping and iterative models seek earlier or repeated feedback.
