The selection of Spiral Model based on characteristics of requirements:
(A) Are requirements easily understandable and defined?
(B) Do we change requirements quite often?
(C) Can we define requirements early in the cycle?
(D) Requirements are indicating a complex to be built
Choose the correct answer from the options given below:
1.(C) Only
2.(B) Only
3.(B) and (D) Only✓ Correct
4.(A) and (C) Only
Solution
The correct answer is (B) and (D) Only
EXPLANATION:
The Spiral Model in software development is a risk-driven model which involves four phases: planning, risk analysis, engineering and evaluation. This model is ideal for large, complex and innovative projects where the requirements might not be clearly defined upfront or are highly likely to evolve during the course of the project.
Based on these characteristics, the right answer about the applicability of Spiral Model is:
(B) Do we change requirements quite often? - This indeed aligns with the Spiral Model as changes can be introduced in the system in the subsequent phases, making it highly flexible.
(D) Requirements are indicating a complex to be built - Spiral model is suitable for complex projects as the risk analysis phase allows for thorough identification and mitigation of any potential issues, especially important in a complex project.
