Question 1

All of the following are examples of agile software development methodologies EXCEPT:

Accepted Answer

SDLC stands for "Software Development Life Cycle," which is a traditional linear approach to software development, and is not considered an agile methodology. The other choices (Scrum, Lean, Feature-Driven Development, and Extreme Programming) are all examples of agile software development methodologies.

Question 2

The riskiest approach to system implementation is a parallel conversion.

Accepted Answer

Parallel conversion is considered one of the safer approaches to system implementation because the old and new systems run simultaneously for a period, reducing the risk of data loss or system failure.

Question 3

A project is a permanent endeavor undertaken to create a unique product or service.

Accepted Answer

A project is a temporary endeavor undertaken to create a unique product, service, or result.

Question 4

To transform resources into profits, organizations combine two types of work-operations and ________.

Accepted Answer

The answer of To transform resources into profits, organizations combine...

Question 5

Integrating within the organization is a mechanism to manage project complexity, and includes frequent team meetings as an example.

Accepted Answer

Integrating within the organization, such as through frequent team meetings, is a mechanism to manage project complexity and ensure coordination among team members.

Question 6

Strong project leadership can trade off against strong project management processes. That is, if the leader is not strong, then processes can be strengthened to make up for it. And if the processes are weak, a strong leader is needed.

Accepted Answer

This statement is true, as strong project leadership and strong project management processes are complementary but can sometimes compensate for each other's shortcomings.

Question 7

According to Brooks, adding extra personnel to a system project more often makes it later, not earlier.

Accepted Answer

Brooks' law states that adding manpower to a late software project makes it later. This is because new team members need to be trained, and communication overhead increases as more people are added to the project. Therefore, adding extra personnel often results in a slower completion of the project.

Question 8

Adding more people to a project can be helpful, but most projects are not made more efficient by simply adding labor.

Accepted Answer

Simply adding more people to a project does not necessarily mean the project will become more efficient. The project may require additional resources or coordination to ensure the increased labor is properly utilized.

Question 9

Small projects that are low in complexity and low in clarity are low in risk.

Accepted Answer

Low complexity does not necessarily equate to low risk; projects with low clarity can have high risks due to uncertainties and unknowns.

Question 10

Project cost and schedule estimates should be made only using documented facts.

Accepted Answer

While documented facts should be a primary source of information in making project cost and schedule estimates, there may be cases where expert judgment and past experience are also used to make estimates. However, these sources should be documented and well-documented assumptions should be used.

Question 11

In calling something a "project," the issues of uniqueness and temporariness are very important.

Accepted Answer

A project is typically something that is unique and temporary, with a specific goal or outcome to be achieved within a defined timeframe. Unlike ongoing processes or routines, projects have a clear beginning and end, and require specific resources and effort to complete. Therefore, the issues of uniqueness and temporariness are essential to understanding what constitutes a project.

Question 12

A research firm found that a majority of software projects are delivered late or over budget or simply fail to meet expectations.

Accepted Answer

This statement is supported by research conducted by the Standish Group, which found that only 29% of software projects were successful, while 52% were considered challenged and 19% failed altogether. This indicates that a majority of software projects either run over budget, are delivered later than expected, or fail to meet the desired outcomes or specifications.

Question 13

A system development life cycle:

Accepted Answer

The answer of A system development life cycle:
...

Question 14

Prototyping and RAD can be used to minimize problems of defining a scope that is too broad or narrow at the beginning of a project.

Accepted Answer

Prototyping and RAD allow for a more iterative approach to development, allowing for an evolving scope that can be adjusted as the project progresses. This can help minimize the risk of having a scope that is either too broad or too narrow at the beginning of the project.

Question 15

All of the following are drawback of prototyping EXCEPT:

Accepted Answer

The drawback mentioned in option B is not actually a drawback of prototyping but rather a limitation of the tools used to create an operational version. The other options provide valid drawbacks of prototyping.

Question 16

The mantra for prototyping is "code a little, test a little."

Accepted Answer

The answer of The mantra for prototyping is "code a...

Question 17

Open source software is free but often an organization will have to pay for training and technical support for the software.

Accepted Answer

While open source software itself is free, organizations may choose to pay for additional services such as training or technical support.

Question 18

The maintenance and review phase is the longest phase of the software development lifecycle.

Accepted Answer

The maintenance and review phase involves ongoing updates, bug fixes and improvements to the software, and can last indefinitely, making it the longest phase of the software development lifecycle.

Question 19

If someone wants a system cheaply, quickly, and with a large scope, we can conclude:

Accepted Answer

The Project Triangle, also known as the Triple Constraint, posits that among scope, cost, and time, typically only two can be optimized at the expense of the third. Therefore, wanting a system that is cheap, quick, and broad in scope is often unrealistic, making all the given options correct interpretations of this scenario.

Question 20

To support a common language and improve communication, a project manager should develop a private collection of acronyms and make frequent use of them.

Accepted Answer

While it may be helpful to develop a glossary of terms to ensure everyone on the team is speaking the same language, excessive use of acronyms could actually hinder communication if team members are not familiar with them. It is important to strike a balance and ensure that everyone understands the language being used.
