ITPEC IP October 2023 Question 50
ITPEC IP October 2023 — Question 50 of 100
The prototyping model creates an early trial system so users and developers can clarify requirements, evaluate the interface, and examine feasibility or performance before committing to later development. Feedback exposes misunderstandings early, reducing the risk and cost of rework. The prototype may be discarded or evolved, depending on the approach.
Answer (a)
Why not others:
- (b) describes a risk-driven spiral model
- (c) describes incremental development, where working functionality is delivered in successive portions
- (d) describes the sequential waterfall model
Key rule: Prototyping learns through an early working model; spiral development is risk-driven, incremental development grows functionality, and waterfall proceeds phase by phase.
