Q191.
What is the final step in the COTS(Commercial Off The Shelf) selection process?

a.

Define requirements

b.

Select components

c.

Rank the components

d.

Select the most appropriate component or iterate

Discuss
Answer: (d).Select the most appropriate component or iterate Explanation:The final step in the COTS(Commercial Off The Shelf) selection process is to select the most appropriate component or iterate.
Q192.
What is the Weighted Scoring Method in COTS selection?

a.

A method where components are ranked based on a set of predefined criteria.

b.

A method where components are ranked based on their weight.

c.

A method where components are ranked based on the number of requirements they satisfy.

d.

A method where components are ranked based on the scores they receive for each requirement.

Discuss
Answer: (a).A method where components are ranked based on a set of predefined criteria. Explanation:In the Weighted Scoring Method, each requirement is given a weight, and the alternatives are given a score for each requirement, say on a scale from 1 to 5.
Q193.
What is the purpose of using an iterative process in COTS selection?

a.

To reduce the number of components to be evaluated.

b.

To improve the accuracy of the ranking.

c.

To reduce the number of requirements to be evaluated.

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:An iterative process is followed when the set of components and requirements are too large to make a complete analysis and ranking in one step feasible. The iterative process is used to reduce the number of components to be evaluated and improve the accuracy of the ranking.
Q194.
What is a drawback of the Weighted Scoring Method?

a.

Every criterion cannot be compensated for by any other criterion.

b.

Every criterion can be compensated for by any other criterion.

c.

The method only considers the number of requirements satisfied.

d.

The method only considers the weight of each requirement.

Discuss
Answer: (b).Every criterion can be compensated for by any other criterion. Explanation:A major drawback of WSM is that every criterion can be compensated for by any other criterion. In other words, a component can make it to the next round even though it scores low on a certain criterion.
Q195.
How does the Analytic Hierarchy Process overcome the drawback of the Weighted Scoring Method?

a.

By considering the number of requirements satisfied.

b.

By considering the weight of each requirement.

c.

By considering every criterion as separate and non-compensating.

d.

By considering the scores received for each requirement.

Discuss
Answer: (c).By considering every criterion as separate and non-compensating. Explanation:The Analytic Hierarchy Process overcomes the drawback of the Weighted Scoring Method by considering every criterion as separate and non-compensating. This helps to ensure that a component is not chosen even though it scores low on a certain criterion.
Q196.
What is the purpose of the requirements specification in a document-driven development project?

a.

To understand the results of the analysis phase

b.

To communicate the results of the analysis phase to others

c.

To serve as an anchor point for subsequent steps

d.

To provide a mathematical description of the results of the analysis phase

Discuss
Answer: (b).To communicate the results of the analysis phase to others Explanation:The requirements specification is an a posteriori reconstruction of the results of the requirements engineering phase, and its purpose is to communicate these results to others.
Q197.
What is the preferred form of the requirements specification?

a.

Precise and mathematical

b.

Readable and understandable

c.

Both precise and readable

d.

None of the above

Discuss
Answer: (c).Both precise and readable Explanation:The requirements specification should be precise and even mathematical, but also understandable to the user, often meaning a readable document using natural language and pictures. A compromise must be sought.
Q198.
What are some of the requirements for the requirements specification document?

a.

Correctness

b.

Ambiguity

c.

Completeness

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Besides readability and understandability, a requirements specification should be correct, unambiguous, and complete.
Q199.
What is a requirements specification in a document-driven development project?

a.

A document that describes the results of the requirements engineering phase

b.

A mathematical description of the end product

c.

A readable document using natural language and pictures

d.

A document that describes the design phase

Discuss
Answer: (a).A document that describes the results of the requirements engineering phase Explanation:The requirements specification is an a posteriori reconstruction of the results of the requirements engineering phase and its purpose is to communicate these results to others.
Q200.
What should a requirements specification be according to IEEE830, 1993?

a.

Correct

b.

Ambiguous

c.

Incomplete

d.

Unreadable

Discuss
Answer: (a).Correct Explanation:According to IEEE830, 1993, a requirements specification should be correct and its correctness should be validated against other documents and the actual needs of the users.
