ITPEC IP April 2021 Question 50
ITPEC IP April 2021 — Question 50 of 100
Prototyping creates an early trial model so users can examine it and clarify requirements. Their feedback reveals misunderstandings, missing functions, and usability needs before full-scale construction, reducing expensive rework discovered only in later acceptance testing.
Answer (d)
Why not others:
- object-oriented and data-oriented approaches structure analysis and design but do not specifically mean an early trial model
- the spiral model is an iterative, risk-driven life-cycle model that may use prototypes, but the described method itself is prototyping
Key rule: A prototype is built for early user feedback and requirements validation.
