Q91.
What are the five scale factors used in COCOMO 2?

a.

Prencedentedness, development flexibility, architecture/risk resolution, team cohesion, process maturity

b.

Novelty, conformance, risk elimination, stakeholder interactions, project organization maturity

c.

Novelty, flexibility, risk resolution, team dynamics, maturity of project organization

d.

Prencedentedness, flexibility, risk management, team dynamics, project maturity

Discuss
Answer: (a).Prencedentedness, development flexibility, architecture/risk resolution, team cohesion, process maturity Explanation:The five scale factors used in COCOMO 2 are Prencedentedness, development flexibility, architecture/risk resolution, team cohesion, and process maturity. These factors account for the novelty of the project, the need for conformance with pre-established and external interface requirements, the percentage of significant risks that have been eliminated, possible difficulties in stakeholder interactions, and the maturity of the project organization according to the Capability Maturity Model.
Q92.
How is reuse catered for in the original COCOMO model?

a.

by adjusting the unadjusted value KLOC using a formula

b.

by considering the fractions of the system that require redesign, recoding, and re-integration

c.

by using a different set of cost drivers

d.

by using a different exponent in the effort equation

Discuss
Answer: (b).by considering the fractions of the system that require redesign, recoding, and re-integration Explanation:In the original COCOMO model, reuse is catered for by separately considering the fractions of the system that require redesign, recoding, and re-integration. An adjustment factor AAF is then given by the formula AAF = 0.4DM + 0.3CM + 0.3IM. An adjusted value AKLOC, given by AKLOC = KLOC * AAF/100 is next used in the COCOMO formulae, instead of the unadjusted value KLOC. This way, a lower cost estimate is obtained if part of the system is reused.
Q93.
How is the exponent b in the COCOMO 2 effort equation determined?

a.

by using a fixed value for all projects

b.

by using a formula that takes into account five scale factors

c.

by using the number of KSLOC or UFP as a base measure

d.

by using the number of Object Points as a base measure

Discuss
Answer: (b).by using a formula that takes into account five scale factors Explanation:In COCOMO 2, the exponent b in the effort equation is determined by a formula that uses five scale factors. These scale factors are rated on a six-point scale and include factors such as unprecedentedness, development flexibility, architecture/risk resolution, team cohesion, and process maturity. The formula used to calculate the exponent b is b=1.01+0.01 * ฮฃWi.
Q94.
How is the effort needed to determine whether a component is appropriate for the present application represented in COCOMO 2?

a.

as a fixed percentage

b.

as a range from 0% to 8%

c.

as a fixed number of lines of code

d.

not represented

Discuss
Answer: (b).as a range from 0% to 8% Explanation:In COCOMO 2, the effort needed to determine whether a component is appropriate for the present application is represented as a range from 0% (no extra effort required) to 8% (extensive test, evaluation and documentation required), which is denoted by the degree of assessment and assimilation (AA).
Q95.
How is the equivalent number of new lines of code calculated in COCOMO 2?

a.

by multiplying the number of lines of code by the adjustment factor AAF

b.

by multiplying the number of lines of code by ( AAF+SU+AA )/100

c.

by subtracting the number of reused lines of code from the total number of lines of code

d.

not calculated

Discuss
Answer: (b).by multiplying the number of lines of code by ( AAF+SU+AA )/100 Explanation:In COCOMO 2, the equivalent number of new lines of code is calculated by multiplying the number of lines of code by (AAF+SU+AA)/100, where AAF is the adjustment factor, SU is the software understanding increment, and AA is the degree of assessment and assimilation.
Q96.
What are the factors that impact the cost of reuse in COCOMO 2?

a.

The quality of the code being reused

b.

The amount of effort needed to test the applicability of the component to be reused

c.

The cost of developing reusable components

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:COCOMO 2 uses a more elaborate scheme to handle reuse effects. This scheme reflects two additional factors that impact the cost of reuse: the quality of the code being reused and the amount of effort needed to test the applicability of the component to be reused.
Q97.
What is the extra effort needed to reuse code if it is strongly modular, matches the application, and is well-documented?

a.

0%

b.

10%

c.

25%

d.

50%

Discuss
Answer: (b).10% Explanation:If the software to be reused is strongly modular, strongly matches the application in which it is to be reused, and the code is well-organized and properly documented, then the extra effort needed to reuse this code is relatively low, and estimated to be 10%.
Q98.
What is the range of the degree of assessment and assimilation (AA) in COCOMO 2?

a.

0% to 50%

b.

10% to 20%

c.

0% to 8%

d.

20% to 30%

Discuss
Answer: (c).0% to 8% Explanation:The degree of assessment and assimilation (AA) in COCOMO 2 denotes the effort needed to determine whether a component is appropriate for the present application. It ranges from 0% (no extra effort required) to 8% (extensive test, evaluation and documentation required).
Q99.
How is the equivalent kilo number of new lines of code (EKLOC) calculated in COCOMO 2?

a.

EKLOC=KLOC*(AAF+SU+AA)/100

b.

EKLOC=KLOC*(AA+SU)/100

c.

EKLOC=KLOC*(AAF+AA)/100

d.

EKLOC=KLOC*(AAF*SU*AA)/100

Discuss
Answer: (a).EKLOC=KLOC*(AAF+SU+AA)/100 Explanation:The equivalent kilo number of new lines of code, EKLOC is calculated by multiplying the number of lines of code (KLOC) with the adjustment factor AAF, the software understanding increment SU, and the degree of assessment and assimilation (AA) and dividing by 100.
Q100.
What is one of the main problems in applying cost estimation models?

a.

Lack of data about past projects

b.

Lack of expertise in the estimators

c.

Political arguments entering the arena

d.

Difficulty in collecting data

Discuss
Answer: (a).Lack of data about past projects Explanation:One of the main problems in applying these models is the sheer lack of quantitative data about past projects.
