Question 1

In the context of economic feasibility, which of the following statements is true of opportunity costs?
A) They measure what an individual would miss by not having an information system or feature.
B) They measure costs involved in training employees who will be using the information system.
C) They measure the changes in the scope of an information system after the analysis and design phases.
D) They measure fixed and variable costs involved in running a system.

Accepted Answer

Opportunity costs refer to what an individual would miss out on or give up by choosing one alternative over another. In the context of economic feasibility, opportunity costs will measure the benefits that will be foregone by not implementing an information system or feature.

Question 2

During the _____ of the systems development life cycle (SDLC), analysts investigate a proposed solution's feasibility and determine how best to present the solution to management to obtain funding.
A) planning phase
B) requirements-gathering phase
C) design phase
D) implementation phase

Accepted Answer

During the planning phase of the SDLC, analysts evaluate a proposed solution's feasibility and develop a plan for presenting it to management. This includes determining the costs and benefits of the solution and outlining how it will be implemented.

Question 3

The__________approach treats process and data independently and is a sequential approach that requires completing the analysis before beginning the design of information systems.
A) joint application design
B) structured systems analysis and design
C) object-oriented
D) class-responsibility collaboration
E) Select

Accepted Answer

The structured systems analysis and design approach treats process and data as separate entities and requires the completion of analysis before moving on to the design phase. This approach is based on a set of formal methods and techniques to break down complex systems into smaller, more manageable pieces. Joint application design, object-oriented, and class-responsibility collaboration approaches do not necessarily treat process and data independently or require a sequential approach.

Question 4

_____ is the measure of how well a proposed solution will work in an organization and how internal and external customers will react to it.
A) Economic feasibility
B) Technical feasibility
C) Operational feasibility
D) Legal feasibility

Accepted Answer

Operational feasibility is the measure of how well a proposed solution will work in an organization and how internal and external customers will react to it. Economic feasibility measures the cost-effectiveness of the solution, technical feasibility assesses whether the solution can be developed with available technology, and legal feasibility evaluates compliance with applicable laws and regulations. However, operational feasibility concerns the practicality of implementing and adopting the solution within the organization’s existing operations and culture.

Question 5

During the implementation phase of the systems development life cycle (SDLC), _____.
A) a team assesses how a system is working and takes steps to keep the system up and running
B) analysts define the organizational problem and generate alternatives for solving it
C) analysts choose the solution that is the most realistic and offers the highest payoff for the organization
D) the proposed solution is transferred from paper to action, and a team configures the system and procures components for it

Accepted Answer

During the implementation phase of the SDLC, the proposed solution is transferred from paper to action, and a team configures the system and procures components for it. This involves designing, building, testing, and installing the new system or modifying the existing system to meet the user's needs. Therefore, option D is the correct choice. Options A, B, and C are related to the earlier phases of SDLC, including planning, analysis, and design, respectively.

Question 6

Which of the following is a key feature of extreme programming (XP)?
A) Procurement of new equipment
B) Investigation of environments with poorly defined problems
C) Immediate feedback from users
D) Emphasis on limiting a project's scope

Accepted Answer

XP emphasizes continuous communication and collaboration with users, including immediate feedback on working software. This helps to ensure that the final product meets user needs and expectations. Procurement of new equipment and investigation of environments with poorly defined problems are not specifically related to XP, and while limiting a project's scope can be important, it is not a key feature unique to XP.

Question 7

One shortcoming of rapid application development (RAD) is _____.
A) that it has a narrow focus, which might limit future development
B) that building an application takes more time
C) its lack of reusability of small, self-contained blocks of codes
D) its inflexibility to adjust to systems' changing needs

Accepted Answer

Rapid Application Development (RAD) focuses on quick prototyping and iterative delivery, which can sometimes result in a narrow focus on immediate application requirements. This narrow focus might limit the application's adaptability and scalability in the future, as it may not consider broader or future development needs adequately.

Question 8

In the _____ of the systems development life cycle (SDLC), a problem is defined and alternatives are generated for solving it.
A) planning phase
B) requirements-gathering and analysis phase
C) designing and prototype-development phase
D) implementation phase

Accepted Answer

The requirements-gathering and analysis phase is where the problem is defined and alternatives are generated for solving it. This phase involves gathering information from various sources about the problem and analyzing it to create a comprehensive understanding of the situation. It is only after this phase that alternatives can be generated and evaluated for their feasibility and effectiveness.

Question 9

__________prototypes are used to market a proposed system to users and management by showing some of its features and demonstrating how beneficial it could be to the organization.
A) Proof-of-concept
B) Self-sourcing
C) Selling
D) Phased-in-phased-out
E) Select

Accepted Answer

Selling prototypes are used to demonstrate the features and benefits of a proposed system to users and management, aiming to gain their support and approval.

Question 10

During the design phase of the systems development life cycle (SDLC), the _____ is created for a specific platform, such as choosing Dell servers running Ubuntu Linux and Java for the programming language.
A) virtual design
B) physical design
C) conceptual design
D) logical design

Accepted Answer

Physical design involves making decisions about hardware and software platforms and selecting specific technologies and vendors to use in the system. This includes choosing a specific platform, such as Dell servers running Ubuntu Linux and Java as the programming language, which are physical components of the system. The other design phases (conceptual design, logical design, and virtual design) are more focused on overall system requirements, data flow, and architecture, rather than specific hardware and software selections.

Question 11

_____ helps reduce the backlog in producing information systems and improve flexibility in responding to users' information needs.
A) Intersourcing
B) Outsourcing
C) Self-sourcing
D) Crowdsourcing

Accepted Answer

Self-sourcing is a practice where employees of an organization develop their own IT solutions. This helps reduce the backlog in producing information systems as employees can quickly respond to their own information needs without having to rely on the IT department. It also increases flexibility as employees are able to tailor their solutions to their specific needs. Intersourcing, outsourcing, and crowdsourcing all involve relying on external resources, which may not necessarily reduce backlog or improve flexibility in the same way as self-sourcing.

Question 12

Which of the following statements is true of Critical Path Method (CPM)?
A) Activities on the critical path take the shortest time to be completed.
B) It determines the critical path for the completion of a series of interrelated activities.
C) Activities that are on the critical path are flexible and can be delayed without delaying a project.
D) A delay in the activities of a project does not affect the scheduled delivery of the project.

Accepted Answer

The Critical Path Method (CPM) is a project management technique used to determine the critical path for the completion of a series of interrelated activities. Activities on the critical path are the ones that must be completed on time in order to complete the entire project on schedule. Any delay in the activities on the critical path will delay the completion of the project. Therefore, statement A and C are false, and statement D is also false because any delay in the project will affect the scheduled delivery.

Question 13

_____ is concerned with whether a new system can be completed on time.
A) Economic feasibility
B) Technical feasibility
C) Operational feasibility
D) Scheduling feasibility

Accepted Answer

Scheduling feasibility refers to the feasibility of completing a new system within the given time constraints. Economic feasibility is concerned with the financial aspects of a new system, technical feasibility is concerned with whether the required technology exists or can be developed, while operational feasibility looks at whether the new system will be accepted and used by its intended users.

Question 14

Which of the following is an advantage of the joint application design (JAD) approach?
A) It incorporates varying viewpoints from different functional areas of an organization to help ensure that collected requirements for an application is not too narrow or one-dimensional in focus.
B) It provides a method for investigating an environment in which a problem is poorly defined and information is difficult to gather.
C) It reduces the need to train information system users and increases the system's chance of success by encouraging users' involvement.
D) It improves communication among users, top management, and information systems personnel because seeing a concrete model often prompts potential users of the system to ask questions, express opinions, and so forth.

Accepted Answer

The answer of Which of the following is an advantage...

Question 15

__________is an incremental development process that has less emphasis on team coding and more emphasis on limiting a project's scope.
A) The V-shaped model
B) The joint application design approach
C) Rapid prototyping
D) Agile methodology
E) Select

Accepted Answer

The statement describes the Agile methodology, which emphasizes iterative and incremental development with a focus on adaptability and collaboration. It involves regular feedback and communication with stakeholders and allows for changes to be made throughout the development process. This approach is well-suited for projects with changing requirements or where the end goal is not clearly defined at the outset.

Question 16

In the planning phase of the systems development life cycle (SDLC), _____ assesses an information system's costs and benefits.
A) economic feasibility
B) technical feasibility
C) operational feasibility
D) legal feasibility

Accepted Answer

Economic feasibility assesses whether or not the benefits of implementing an information system outweigh its costs in terms of financial investment, time, and effort. This phase helps organizations determine whether investing in a new system or upgrading an existing one is a viable option.

Question 17

__________refers to the trend of end users developing their own information systems with little or no formal assistance from an information systems team.
A) Insourcing
B) Outsourcing
C) Self-sourcing
D) Crowdsourcing
