Question 1

A key principle of the scrum approach for agile development is that users cannot change their minds during a project.

Accepted Answer

One of the primary principles of the Scrum approach is its flexibility and ability to adapt to change. Users are encouraged to provide feedback and change their requirements as needed throughout the project, allowing for continuous improvement and a better end result.

Question 2

With agile development, a company develops only what it needs right now to be successful.

Accepted Answer

Agile development prioritizes delivering valuable and functional features in small increments. This means that the development team focuses on building only what is necessary for the current stage of the project, allowing for flexibility and responsiveness to changes in requirements and business needs.

Question 3

Evaluating the benefits of IT projects is more complex than evaluating their costs for all of the following reasons except:
A) Benefits are harder than costs to quantify.
B) Benefits tend to be more tangible than costs.
C) IT can be used for several different purposes.
D) The probability of obtaining a return from an IT investment is based on the probability of implementation success.
E) The proposed system may be "cutting edge."

Accepted Answer

Benefits are typically harder to quantify than costs, IT can be used for multiple purposes, the probability of implementation success affects the potential return, and the proposal being "cutting edge" can create uncertainty. The only statement that is incorrect is that benefits tend to be more tangible than costs. In many cases, costs are more easily quantifiable and measurable than the benefits of an IT project.

Question 4

Object-oriented development focuses on properties and operations.

Accepted Answer

Object-oriented development is a programming paradigm that focuses on modeling real-world entities as objects, which have properties (attributes) and operations (methods). Therefore, the statement is true.

Question 5

Which of the following systems acquisition methods saves the company's time, enables the company to select software that has been used for similar problems in other organizations, and allows the company to try out the software?
A) Systems development life cycle
B) Prototyping
C) End-user development
D) Buy option
E) Object-oriented development

Accepted Answer

The buy option allows a company to save time by purchasing off-the-shelf software that has already been developed and tested for similar problems in other organizations. This method also often includes the possibility of a trial period to test the software before making a final decision.

Question 6

The information systems planning process proceeds in which order?
A) Organization mission - organization strategic plan - IS strategic plan - new IT architecture
B) Organization mission - IS strategic plan - organization strategic plan - IS operational plan
C) Organization strategic plan - organization mission - IS strategic plan - new IT architecture
D) IT architecture - IS strategic plan - organization strategic plan - organization mission
E) IS development projects - IS operational plan - new IT architecture - organization mission

Accepted Answer

The information systems planning process begins with establishing the organization's mission, followed by developing the organization's strategic plan. The next step is to create an IS strategic plan that supports the organization's strategic plan. Lastly, an appropriate IT architecture is developed to support the IS strategic plan.

Question 7

Which of the following systems acquisition methods can result in a company's acquiring software that is controlled by another company, may be difficult to enhance or modify, and may not support the desired business processes?
A) Systems development life cycle
B) Prototyping
C) End-user development
D) Buy option
E) Component-based development

Accepted Answer

The "buy option" is a system acquisition method where a company purchases existing software from another company. This method can result in the company acquiring software that is difficult to enhance or modify if the other company maintains control over the software. Additionally, the purchased software may not support the desired business processes, as it was not specifically designed for the company's needs.

Question 8

Refer IT's About Business 13.4 - Atlassian Helps Manage Large Software Projects: Making too much information about the projects available to the software developers will confuse them and slow down the development time.

Accepted Answer

Providing the right amount of relevant information and tools for managing it, like Atlassian's software, can actually help developers prioritize tasks, collaborate more efficiently, and ultimately speed up development time rather than slow it down.

Question 9

Which of the following is not a part of the typical IS operational plan?
A) The mission of the IS function
B) The organizational mission
C) The IT architecture
D) The application portfolio
E) The IS function's estimate of its goals

Accepted Answer

The organizational mission is not a part of the typical IS operational plan, as it is a broader company-wide statement of purpose and direction. The other options are all components of an IS operational plan. A) The mission of the IS function defines the purpose and goals of the IS department. C) The IT architecture outlines the technical infrastructure and standards that guide the design and development of systems. D) The application portfolio lists the software applications used by the organization and their characteristics. E) The IS function's estimate of its goals is a projection of performance objectives and milestones.

Question 10

Which of the following is not an advantage of the buy option for acquiring IS applications?
A) Few types of off-the-shelf software are available, thus limiting confusion.
B) The software can be tried out.
C) The buy option saves time.
D) The company will know what it is getting.
E) All of the above

Accepted Answer

Option A is not an advantage of the buy option. Instead, it is a possible disadvantage because few types of off-the-shelf software can limit choices and make it harder to find the best fit for the company's needs. Options B, C, D are all advantages of the buy option.

Question 11

Prototyping allows the users to clarify their information requirements as they use the prototype.

Accepted Answer

Prototyping is an iterative process where users can provide feedback and clarify their information requirements as they interact with the prototype. This allows for a more user-centered approach to the design and development of systems or products.

Question 12

A company's IT application portfolio is
A) A list of existing application the company owns.
B) A list of applications that need to be updated.
C) A list of applications that need to be removed.
D) A list of applications that need to be replaced.
E) A list of application to be added or modified.

Accepted Answer

An IT application portfolio is a list of applications that the company owns, plans to modify or add in the future. Therefore, the best choice is E, which states that an IT application portfolio is a list of applications to be added or modified. The other options, A, B, C, and D, only focus on a partial aspect of the portfolio, such as existing applications, updates, removals, or replacements.

Question 13

Which of the following statements about determining the costs and benefits of IT investments is false?
A) Some costs are fixed.
B) Costs do not end when the system is installed.
C) Many IT projects end up being over budget.
D) Benefits are hard to quantify because implementing new technology could be used for multiple purposes.
E) Benefits are hard to quantify because they are tangible.

Accepted Answer

The statement "Benefits are hard to quantify because they are tangible" is false. Benefits are actually hard to quantify because they are often intangible, such as increased efficiency, improved customer satisfaction, or enhanced decision-making abilities.

Question 14

Joint application design is used to collect user requirements.

Accepted Answer

Joint application design (JAD) is a process used to collect user requirements with the involvement of stakeholders, users, and developers in a workshop-like setting. Therefore, the statement is true.

Question 15

_____ is a method of delivering software in which a vendor hosts the applications and customers access these applications over the Internet.
A) Software-as-a-Service
B) Prototyping
C) Leasing the application
D) Service-oriented architecture
E) The buy option

Accepted Answer

Software-as-a-Service (SaaS) is a method of delivering software in which a vendor hosts the applications and customers access these applications over the Internet. The vendor is responsible for maintaining and updating the software, while the customers pay for usage on a subscription basis. This has become a popular delivery model for business applications, such as customer relationship management (CRM), enterprise resource planning (ERP), and human resource management (HRM) systems.

Question 16

Which of the following systems acquisition methods is time consuming, costly, and may produce excessive documentation?
A) Systems development life cycle
B) Prototyping
C) End-user development
D) External acquisition
E) Object-oriented development

Accepted Answer

The Systems development life cycle (SDLC) involves a step-by-step approach for building information systems, which can be very time-consuming, costly, and produce excessive documentation. The SDLC method is often used in large organizations with complex IT implementations, where a high degree of thoroughness and control is necessary. Prototyping is a faster, more iterative approach to development, where a working model is built and tested before the final product is produced. End-user development involves users creating their own systems without IT involvement, and is not typically costly or time-consuming. External acquisition involves purchasing a pre-built system from a third-party vendor, and may or may not be costly or time-consuming depending on the specific solution. Object-oriented development is a specific approach to programming and design, which does not necessarily dictate the level of documentation or cost.

Question 17

A company's IT architecture includes all of the following except:
A) Hardware and software
B) Networks
C) Database management systems
D) The members of the IT staff
E) How IT decisions will be made

Accepted Answer

The members of the IT staff are not a part of the company's IT architecture, but rather the individuals who work within and manage it. The IT architecture encompasses the technical components, such as hardware, software, networks, and database management systems, as well as the decision-making processes related to IT.

Question 18

Which of the following systems acquisition methods requires staff to systematically go through every step in the development process and has a lower probability of missing important user requirements?
A) Systems development life cycle
B) Prototyping
C) End-user development
D) External acquisition
E) Object-oriented development

Accepted Answer

The systems development life cycle (SDLC) requires systematic steps to be followed in the development process, ensuring that important user requirements are not missed. Prototyping, end-user development, external acquisition, and object-oriented development do not necessarily follow a systematic step-by-step process and may lead to important requirements being overlooked.

Question 19

Which of the following are disadvantages of the buy option for acquiring IS applications?
A) The software may not exactly meet the company's needs.
B) The software may be impossible to modify.
C) The company will not have control over software improvements.
D) The software may not integrate with existing systems.
E) All of the above

Accepted Answer

All of the options listed are potential disadvantages of the buy option for acquiring IS applications. It is important for a company to carefully evaluate and research potential software options before making a purchase to ensure that the selected software will meet their needs and integrate with existing systems. Additionally, companies should consider the level of control they will have over the software and any potential limitations on modifications or improvements.

Question 20

Which of the following statements is false?
A) Companies that use Software-as-a-Service are running applications on the vendor's hardware.
B) Application service providers are similar to Software-as-a-Service providers.
C) Companies that purchase open-source software cannot modify it.
