Question 1

The return on investment (ROI) method of cost-benefit analysis measures the effectiveness of management in generating profits with its available assets.

Accepted Answer

The ROI method is used to measure the profitability of an investment by dividing the net profit by the investment cost. It helps in evaluating the effectiveness of management in generating profits with the available assets.

Question 2

Open-source applications are basically the same as a proprietary application except for licensing, payment, and support.

Accepted Answer

Open-source applications are typically free to use, modify, and distribute, while proprietary applications are typically licensed for a fee and may have restrictions on their use and modification.

Question 3

The application portfolio in an organization is a set of recommended applications resulting from the planning and justification process in application development.

Accepted Answer

The application portfolio is a compilation of recommended applications resulting from the planning and justification process in application development. It is a strategic tool used to determine which applications are needed, which ones should be retired, and which ones should be replaced or updated.

Question 4

Adding functions after a project has been initiated is called scope creep.

Accepted Answer

Scope creep is the addition of new features, functions or requirements to a project after it has already started. This can cause delays, increased costs, and reduced customer satisfaction.

Question 5

Software rental is a method of delivering software in which a vendor hosts the applications and customers use them over a network, typically the Internet.

Accepted Answer

Software rental describes a model where customers pay to use software for a specific period, but the term for delivering software over a network, typically the Internet, is known as Software as a Service (SaaS).

Question 6

The buy option is particularly attractive if the software vendor allows the company to modify the package to meet its needs.

Accepted Answer

If the vendor allows modification of the software, the buy option can be more appealing as the company can tailor it to its specific requirements.

Question 7

The IS operational plan is a set of projects that will be executed by the IS department and by functional area managers.

Accepted Answer

The IS operational plan is a set of projects that will be executed by the IS department and functional area managers to achieve the goals and objectives of the organization.

Question 8

Technical feasibility determines if the project is an acceptable financial risk and if the organization can afford the expense and time needed to complete the project.

Accepted Answer

Technical feasibility focuses on whether the project can be accomplished using current technology and resources available, not on financial feasibility. Financial feasibility is evaluated separately.

Question 9

Insourcing application development is usually less time consuming and less expensive than buying or leasing.

Accepted Answer

Insourcing application development requires setting up infrastructure, hiring skilled developers, providing training, and maintaining the development process. This can be time-consuming and expensive compared to buying or leasing ready-made solutions, which saves time and money.

Question 10

The SDLC is relatively inflexible.

Accepted Answer

The SDLC (Software Development Life Cycle) follows a fixed process and is divided into specific phases. Once a phase is completed, it cannot be easily changed or revisited, making it a relatively inflexible approach to software development.

Question 11

The SDLC encourages changes to user requirements once they have been established.

Accepted Answer

The SDLC (Software Development Life Cycle) aims to establish user requirements upfront and then proceed with the development process in a systematic way. The goal is to minimize changes to requirements during the later stages of development, as this can lead to higher costs and delays. However, the SDLC does allow for changes to be made if necessary, but these changes should be carefully evaluated before implementation.

Question 12

IT architecture focuses only on the technical aspects of information resources.

Accepted Answer

IT architecture not only focuses on technical aspects of information resources but also includes business processes, organizational structures, and overall goals of the organization. It is a holistic approach to designing and managing information systems.

Question 13

Systems analysis describes how a system will solve the business problem, and systems design describes what the system must do to accomplish the task.

Accepted Answer

Systems analysis is the process of studying and understanding the current system and its problems, and determining the requirements for a new system. Systems design, on the other hand, specifies how the system will meet those requirements, focusing on the architecture, components, and interfaces of the system.

Question 14

Maintenance ends when the new system is implemented and has run long enough for a systems audit.

Accepted Answer

Maintenance is an ongoing process that continues throughout the life cycle of a system, even after a new system is implemented and audited, to ensure it remains effective and up-to-date.

Question 15

Systems maintenance includes debugging and updating a system.

Accepted Answer

Systems maintenance involves checking and fixing any bugs or errors in the system, as well as updating and improving it to ensure its functionality and security.

Question 16

The earlier in the development process that errors are detected, the less expensive they are to correct.

Accepted Answer

This is because detecting errors early on allows for quicker and easier fixes, while errors found late in the development process may require significant time and resources to address, potentially leading to delayed project timelines and increased costs.

Question 17

The IT infrastructure delineates the way an organization's information resources should be used to accomplish its mission.

Accepted Answer

The answer of The IT infrastructure delineates the way an...

Question 18

In a direct conversion, the new system is turned on, and the old system is turned off at a later time.

Accepted Answer

In a direct conversion, the new system is turned on and the old system is turned off at the same time, not at a later time. This is also known as a "big bang" approach.

Question 19

Costs are harder to quantify than benefits.

Accepted Answer

Costs can often be quantified with relative ease, especially direct costs, as they are typically tied to specific financial expenditures. Benefits, on the other hand, can be more challenging to quantify, especially when they involve intangible or long-term outcomes.

Question 20

Pilot conversion is the process in which the new system is introduced in one part of the organization.

Accepted Answer

Pilot conversion involves implementing a new system in a small part of the organization first to test its feasibility and effectiveness before introducing it to the entire organization.
