GATE CS 2014 Set 2 Q.29 (CS Q.19): Functions, Recursion, Scope and Storage Classes

Which one of the following is TRUE?

The requirements document also describes how the requirements that are listed in the document are implemented efficiently.

Consistency and completeness of functional requirements are always achieved in practice.

Prototyping is a method of requirements validation.

Requirements review is carried out to find the errors in system design.

Official answer and solution

Solution

Evaluate standard principles of software requirements engineering and verification/validation.

Statement Analysis:
- (A) False: The Software Requirements Specification (SRS) specifies what the system should do, not how to implement it or achieve implementation efficiency (which belongs to system design and coding).
- (B) False: In practice, real-world requirements documents are rarely 100% complete and consistent due to ambiguous human language, changing user needs, and system complexity.
- (C) True: Prototyping provides an early operational mockup of the system to end-users and stakeholders, enabling them to validate whether the specified requirements meet their actual needs.
- (D) False: Requirements review inspects the requirements document to find defects in the requirements themselves, not errors in the system design.

Final answer

Common trap

Confusing requirements validation (building the right product, often via prototyping) with requirements verification or design review.

The answer is the one in the official GATE answer key. The solution is this site's own explanation.
