ITPEC IP October 2020 Question 50
ITPEC IP October 2020 — Question 50 of 100
The waterfall model divides development into ordered stages and performs each later stage using the approved outputs of earlier stages. A typical flow is requirements, design, implementation, testing, and deployment, with defined deliverables at phase boundaries.
Answer (c)
Why not others:
- repeated movement between design and programming describes iterative refinement
- repeating development for subsystems in response to user requests is incremental or iterative development
- building an early model and refining requirements from feedback is prototyping
Key rule: Waterfall is sequential and phase-oriented; iterative and prototype approaches deliberately use repeated feedback cycles.
