WBJECA 2025 — Computer PYQ
WBJECA | Computer | 2025In the context of Software Development Life Cycle (SDLC), which of the following statements is correct?
Choose the correct answer:
- A.
The Spiral model focuses only on risk identification and not on risk mitigation.
- B.
The Incremental model delivers the complete product only at the final iteration.
- C.
In the Waterfall model, requirements can be changed at any phase without impact.
- D.
The V-Model integrates testing activities corresponding to each development phase.
(Correct Answer)
The V-Model integrates testing activities corresponding to each development phase.
Explanation
Let's analyze each statement based on standard SDLC methodologies:
(A) Incorrect: The Spiral model is renowned for its iterative nature, where risk analysis and risk mitigation are central to every loop of the spiral.
(B) Incorrect: The Incremental model breaks the product into smaller, usable chunks. Each iteration delivers a functional increment of the product, not just the final one.
(C) Incorrect: The Waterfall model is a linear, sequential approach. Requirements are finalized at the start, and changing them in later phases is extremely difficult and costly—it has a high impact.
(D) Correct: The V-Model (Validation and Verification model) is an extension of the Waterfall model where each development phase has a direct, corresponding testing phase. The relationship can be represented as:
Development Phase↔Testing Phase
Correct Answer: (D) The V-Model integrates testing activities corresponding to each development phase.
