ITPEC IP April 2018 — Question 50 of 100
The prototyping model creates an early trial model so users and developers can validate interfaces, requirements, and feasibility before committing to later phases. Early feedback exposes misunderstandings and performance concerns, reducing expensive rework caused by late specification changes.
Answer (a)
Why not others:
- iterative risk-driven development describes the spiral model
- completing the system in functional portions describes incremental development
- a fixed sequence of requirements, design, production, and testing describes the waterfall model
Key rule: Prototyping clarifies uncertain requirements through an early working model and user evaluation.
