a.

Lack of proper planning

b.

Insufficient testing

c.

Poor communication

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Rework in software development can be caused by a variety of factors such as lack of proper planning, insufficient testing, and poor communication.
Q22.
What can integrated project support environments do to improve software development?

a.

Make steps less efficient

b.

Add more steps

c.

Eliminate steps or make steps more efficient

d.

None of the above

Discuss
Answer: (c).Eliminate steps or make steps more efficient Explanation:Integrated project support environments can help improve software development by eliminating steps or making steps more efficient through the use of tools.
Q23.
What are some of the common characteristics of various cost estimation models?

a.

They all use the same measures and cost drivers

b.

They reflect important factors that bear on development cost and effort

c.

They are all based on experiments

d.

They all have the same level of accuracy

Discuss
Answer: (b).They reflect important factors that bear on development cost and effort Explanation:The common characteristics of various cost estimation models are that they reflect important factors that bear on development cost and effort, such as the size of the project, the capabilities of the team, and the amount of rework.
Q24.
What are some of the reasons for the discrepancies between existing cost estimation models?

a.

Different models use different definitions of size and effort

b.

The notion of effort does not always mean the same thing

c.

Most models give a relation between man-months needed and size

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:There are many reasons for the discrepancies between existing cost estimation models, including different definitions of size and effort, different meanings of the term effort, and the use of different measures and cost drivers.
Q25.
What is the main disadvantage of expert-based cost estimation?

a.

It is based on gut feeling

b.

It is not formula-based

c.

It does not take into account the size of the project

d.

It is not accurate

Discuss
Answer: (d).It is not accurate Explanation:The main disadvantage of expert-based cost estimation is that it is not always accurate as it is based on gut feeling and experience rather than a formula or a precise data analysis.
Q26.
Why are algorithmic models not suitable for agile projects?

a.

Iterations are usually fairly small

b.

They do not warrant the effort required by the algorithmic models

c.

Agile projects use different estimation techniques

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Algorithmic models are not suitable for agile projects because iterations are usually small and don't warrant the effort required by these models, and Agile projects use different estimation techniques like user stories, scenarios, and artificial units like points.
Q27.
What is the main disadvantage of shortening the nominal development time?

a.

It can increase the chance of failure

b.

It may lead to unrealistic expectations

c.

It may not be achievable

d.

All of the above

Discuss
Answer: (a).It can increase the chance of failure Explanation:The main disadvantage of shortening the nominal development time is that it increases the chance of failure. When development time is shortened too much, it enters into the "impossible region" where the chances of completing the project on time and within budget becomes slim. This is because reducing the development time means less time for testing, debugging and making necessary changes. Additionally, the team may be required to work under increased pressure and stress, leading to burnout and a reduction in productivity.
Q28.
What is the general form of the equation used to express the correlation between programming effort and program size in algorithmic models?

a.

E=a+bKLOC

b.

E=(a+bKLOC)f(x1;:;xn)

c.

E=KLOCf(a,b,x1;:;xn)

d.

E=KLOCf(x1;:;xn)

Discuss
Answer: (b).E=(a+bKLOC)f(x1;:;xn) Explanation:The general form of the equation used in algorithmic models to express the correlation between programming effort and program size is E=(a+bKLOC)f(x1;:;xn) where KLOC denotes the size of the software and E denotes the effort in man-months, and f(x1;:;xn) is a correction factor depending on the values of x1 to xn.
Q29.
What is the primary cost driver in algorithmic models for software cost estimation?

a.

Experience of the programming team

b.

Software size

c.

Type of programming language

d.

Type of software development project

Discuss
Answer: (b).Software size Explanation:The primary cost driver in algorithmic models for software cost estimation is the software size, measured in lines of code. This nominal cost estimate is then adjusted for various factors that influence productivity (so-called cost drivers).
Q30.
In algorithmic models, what is the value of "c" in the equation E=(a+bKLOC)f(x1;:;xn)?

a.

A constant value

b.

A correction factor based on the values of x1 to xn

c.

A variable value based on the programming team's experience

d.

A value that fluctuates around 1

Discuss
Answer: (d).A value that fluctuates around 1 Explanation:In algorithmic models, the value of "f" in the equation E=(a+bKLOC)f(x1;:;xn) fluctuates around the value of 1. This is based on the available project data and the various factors that influence productivity.
