2. How many feasibility studies is conducted in Requirement Analysis ?
a) Two
b) Three
c) Four
d) None of the mentioned

Answer: b

3. How many phases are there in Requirement Analysis ?
a) Three
b) Four
c) Five
d) Six

Answer: c
Explanation: Problem Recognition, Evaluation and Synthesis (focus is on what not how), Modeling, Specification and Review are the five phases.

4. Traceability is not considered in Requirement Analysis.
a) True
b) False

Answer: b
Explanation: Requirements traceability is concerned with documenting the life of a requirement and providing bi-directional traceability between various associated requirements, hence requirements must be traceable.

5. Requirements analysis is critical to the success of a development project.
a) True
b) False
c) Depends upon the size of project
d) None of the mentioned

Answer: a
Explanation: Requirements must be actionable, measurable, testable, related to identified business needs or opportunities, and defined to a level of detail sufficient for system design.

a) Performance, Design
b) Stakeholder, Developer
c) Functional, Non-Functional
d) None of the mentioned

Answer: b
Explanation: Option a and c are the types of requirements and not the issues of requirement analysis.

7. The requirements that result from requirements analysis are typically expressed from one of three perspectives or views. What is that perspective or view ?
a) Developer
b) User
c) Non-Functional
d) Physical

Answer: d
Explanation: The perspectives or views have been described as the Operational, Functional, and Physical views.All three are necessary and must be coordinated to fully understand the customers’ needs and objectives.

8. Requirements Analysis is an Iterative Process.
a) True
b) False

Answer: a
Explanation: Requirements analysis is conducted iteratively with functional analysis to optimize performance requirements for identified functions, and to verify that synthesized solutions can satisfy customer requirements.

a) Three
b) Four
c) Five
d) Six

Answer: d
Explanation: Retained information, Needed services, Multiple attributes, Common attributes, Common operations and Essential requirements are the six criterion mentioned by Coad and Yourdon.

b) False

Answer: a
Explanation: ‘What’ refers to a system’s purpose, while ‘How’ refers to a system’s structure and behavior.
