Q271.
When is the analysis of technical feasibility of quality requirements done in software development?

a.

At the start of the project

b.

During the software development effort

c.

After the software development effort

d.

At software architecture time

Discuss
Answer: (d).At software architecture time Explanation:The analysis of technical feasibility of quality requirements is usually done at software architecture time.
Q272.
What should be kept in mind while specifying quality requirements?

a.

They should be verifiable

b.

They should not be measurable

c.

They should not appear in the requirements specification

d.

They should not be feasible

Discuss
Answer: (a).They should be verifiable Explanation:Like all other requirements, quality requirements should be verifiable.
Q273.
Why might users ask for more in quality requirements?

a.

They may be difficult to express their true requirements

b.

They are not feasible at all

c.

They are not necessary

d.

They are too easy to achieve

Discuss
Answer: (a).They may be difficult to express their true requirements Explanation:Given the fact that users find it difficult to express their true requirements, they may be inclined to ask for too much where quality requirements are concerned, just "to be on the safe side".
Q274.
What is the role of an early and careful analysis of technical feasibility?

a.

It is done at software architecture time

b.

It may yield surprising answers to a number of important questions

c.

It is not necessary

d.

It may result in wasted money and resources

Discuss
Answer: (b).It may yield surprising answers to a number of important questions Explanation:An early and careful analysis of technical feasibility may yield surprising answers to a number of important questions.
Q275.
What is the purpose of verification and validation in requirements engineering?

a.

To check the syntax and semantics of the requirements specification

b.

To ensure that the requirements specification reflects the mutual understanding of the problem

c.

To validate the requirements in a formal way

d.

To translate the requirements into a form palatable to user inspection

Discuss
Answer: (b).To ensure that the requirements specification reflects the mutual understanding of the problem Explanation:The purpose of verification and validation in requirements engineering is to ensure that the requirements specification reflects the mutual understanding of the problem to be solved by the prospective users and the development organization.
Q276.
How is the requirements specification validated during requirements engineering?

a.

By checking for syntax and semantics through formal means

b.

By involving users in the validation process

c.

By completely validating the specification in a formal way

d.

By translating the requirements into a form palatable to user inspection

Discuss
Answer: (b).By involving users in the validation process Explanation:The requirements specification is validated during requirements engineering by involving users in the validation process. This involves checking the requirements for properties like correctness, completeness, ambiguity, and internal and external consistency.
Q277.
What are the testing techniques applied at the stage of verifying and validating the requirements specification?

a.

Formal testing techniques

b.

Informal testing techniques

c.

Natural-language testing techniques

d.

Animation testing techniques

Discuss
Answer: (b).Informal testing techniques Explanation:Most of the testing techniques applied at the stage of verifying and validating the requirements specification are informal. They are meant to ascertain that the parties involved have the same, proper understanding of the problem and involve techniques such as natural-language paraphrasing, the discussion of possible usage scenarios, prototyping, and animation.
Q278.
What is a critical success factor in requirements engineering?

a.

User participation in the validation process

b.

A formal language representation of the requirements specification

c.

The use of formal testing techniques

d.

A careful study of the correctness of decisions made at each stage

Discuss
Answer: (d).A careful study of the correctness of decisions made at each stage Explanation:A careful study of the correctness of the decisions made at each stage is a critical success factor in requirements engineering.
Q279.
What is a major stumbling block in the requirements engineering process?

a.

Syntax and semantics verification of the requirements specification

b.

Ensuring the requirements specification is expressed in a formal language

c.

Ensuring the user understands the contents of the requirements specification

d.

The use of formal testing techniques

Discuss
Answer: (c).Ensuring the user understands the contents of the requirements specification Explanation:A major stumbling block in the requirements engineering process is ensuring the user understands the contents of the requirements specification.
Q280.
What are some of the informal testing techniques used in the requirements engineering process?

a.

Natural-language paraphrasing

b.

Discussion of possible usage scenarios

c.

Prototyping and animation

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Most of the testing techniques applied at the requirements engineering stage are informal, such as natural-language paraphrasing, discussion of possible usage scenarios, prototyping, and animation.
