This set of Software Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Requirement Analysis”.
1. Which of the following is not a diagram studied in Requirement Analysis ?
a) Use Cases
b) Entity Relationship Diagram
c) State Transition Diagram
d) Activity Diagram
View Answer
Explanation: Activity Diagram comes under the design phase of SDLC.
2. How many feasibility studies is conducted in Requirement Analysis ?
a) Two
b) Three
c) Four
d) None of the mentioned
View Answer
Explanation: Economic feasibility (cost/benefit analysis), Technical feasibility (hardware/software/people, etc.) and Legal feasibility studies are done in Requirement Analysis.
3. How many phases are there in Requirement Analysis ?
a) Three
b) Four
c) Five
d) Six
View Answer
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
View Answer
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
View Answer
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.
6. _________ and _________ are the two issues of Requirement Analysis.
a) Performance, Design
b) Stakeholder, Developer
c) Functional, Non-Functional
d) None of the mentioned
View Answer
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
View Answer
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
View Answer
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.
9. Coad and Yourdon suggested _______ selection characteristics that should be used as an analyst considers each potential object for inclusion in the requirement analysis model.
a) Three
b) Four
c) Five
d) Six
View Answer
Explanation: Retained information, Needed services, Multiple attributes, Common attributes, Common operations and Essential requirements are the six criterion mentioned by Coad and Yourdon.
10. Requirements should specify ‘what’ but not ‘how’.
a) True
b) False
View Answer
Explanation: ‘What’ refers to a system’s purpose, while ‘How’ refers to a system’s structure and behavior.
