Q121.
What is the method that aims to get a more reliable estimate by having the expert produce more than one estimate?

a.

The comparison method of cost estimation

b.

The beta-distribution method

c.

The average method

d.

The optimistic method

Discuss
Answer: (b).The beta-distribution method Explanation:One method that aims to get a more reliable estimate is to have the expert produce more than one estimate, using a beta-distribution.
Q122.
What is the main issue with using the comparison method for cost estimation?

a.

It does not take into account peculiar circumstances and particular characteristics of a specific project

b.

It leads to too optimistic estimates

c.

It is not a point estimate

d.

It does not involve more than one expert

Discuss
Answer: (a).It does not take into account peculiar circumstances and particular characteristics of a specific project Explanation:The main issue with using the comparison method for cost estimation is that it does not take into account peculiar circumstances and particular characteristics of a specific project, which may have a significant impact on the effort required in terms of man-months.
Q123.
What is the impact of a compressed schedule on a software development project?

a.

It decreases the effort required in terms of man-months

b.

It improves the quality of the estimate

c.

It increases the overhead due to communication

d.

It leads to a more reliable estimate

Discuss
Answer: (c).It increases the overhead due to communication Explanation:It increases the overhead due to communication.
Q124.
What is the recommended method to get a more reliable estimate?

a.

Using a single expert

b.

Comparing with earlier projects

c.

Using a point estimate

d.

Having the expert produce more than one estimate

Discuss
Answer: (d).Having the expert produce more than one estimate Explanation:The recommended method to get a more reliable estimate is to have the expert produce more than one estimate, as this obviates the tendency to conceive an optimistic estimate as being realistic.
Q125.
What is the expected effort using the technique of asking for three estimates?

a.

E = (a + 4m + b)/6

b.

E = (a + m +

c.

E = (a + b)/2

d.

E = (a + m)

Discuss
Answer: (a).E = (a + 4m + b)/6 Explanation:The expected effort using the technique of asking for three estimates is E = (a+4m+b)/6, where a is the optimistic estimate, m is the realistic estimate, and b is the pessimistic estimate.
Q126.
What is the impact of software on a project's estimated effort?

a.

It decreases the estimated effort

b.

It does not have any impact on the estimated effort

c.

It increases the estimated effort

d.

It is impossible to determine

Discuss
Answer: (c).It increases the estimated effort Explanation:Software has the tendency to grow, and projects have the tendency to far exceed the estimated effort." This implies that the estimated effort for a project is likely to be higher than initially thought due to the complexity and growth of software.
Q127.
What is the impact of training on software cost estimation?

a.

It decreases the accuracy of the estimate

b.

It improves the accuracy of the estimate

c.

It does not have any impact on the accuracy of the estimate

d.

It increases the accuracy of the estimate

Discuss
Answer: (b).It improves the accuracy of the estimate Explanation:Training improves performance in software cost estimation, as studies in other fields show that inexperienced people tend to overestimate their abilities and performance. Greater self-knowledge is a prime reason for more mature organizations to have fewer cost overruns in software projects.
Q128.
How do requirements set or proposed affect the cost estimate?

a.

They do not affect the cost estimate

b.

They slightly affect the cost estimate

c.

They greatly affect the cost estimate

d.

They moderately affect the cost estimate

Discuss
Answer: (c).They greatly affect the cost estimate Explanation:The cost estimate is one of the requirements that will have an impact on the end result. Choices made during the execution of a project are influenced by cost estimates derived earlier on. The project's behavior is also influenced by the cost estimate.
Q129.
Is it advisable to make a cost estimate if it is not needed?

a.

Yes, it is advisable to make a cost estimate even if it is not needed

b.

No, it is not advisable to make a cost estimate if it is not needed

c.

Yer or No

d.

May be Yes or No

Discuss
Answer: (b).No, it is not advisable to make a cost estimate if it is not needed Explanation:If a cost estimate is not needed, it is wise not making one either.
Q130.
How does shortening the development time of a project affect the manpower required?

a.

It decreases the number of people involved in the project

b.

It increases the number of people involved in the project

c.

It does not affect the number of people involved in the project

d.

None of the above

Discuss
Answer: (b).It increases the number of people involved in the project Explanation:Shortening the development time means an increase in the number of people involved in the project, and that in terms of the Rayleigh curve model, this means an increase of the value "a", the speed-up factor which determines the initial slope of the curve.
