Question 2

Which of the following is a key feature of extreme programming (XP)?

Accepted Answer

Immediate feedback from users is a central feature of extreme programming (XP) methodology. The other options are not necessarily key features of XP.

Question 3

A _____ is a written document with detailed specifications that is used to appeal bids for equipment, supplies, or services from vendors. ​

Accepted Answer

A request for proposal (RFP) is a formal document that outlines in detail what a company is looking for from a vendor and invites vendors to submit their proposals. It includes specifications, requirements, and criteria for evaluation, as well as instructions for how to submit a bid. A bill of materials is a list of materials needed for a particular project or product. A cost-benefit analysis report is a document that compares the costs and benefits of different options or alternatives. A milestone chart is a visual representation of project milestones and timelines. None of these are specific to appealing bids from vendors. Therefore, the best choice is B, request for proposal.

Question 4

_____ is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project. ​

Accepted Answer

The systems development life cycle (SDLC) is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project. Rapid Application Development and Extreme Programming are alternative software development methodologies that are sometimes used instead of the SDLC. The maintenance process model focuses on maintaining and improving existing systems rather than developing new systems.

Question 5

The _____ approach treats process and data independently and is a sequential approach that requires completing the analysis before beginning the design of information systems. ​

Accepted Answer

The description matches the structured systems analysis and design (SSAD) approach, which follows a logical sequence of steps, starting with analysis and ending with implementation. This approach treats the process and data as separate entities and requires a thorough analysis before moving on to the design phase.

Question 6

_____ uses an iterative process that repeats the design, development, and testing steps as needed, based on feedback from users.

Accepted Answer

Rapid application development (RAD) is a software development methodology that emphasizes rapid prototyping and iterative development. It uses an iterative process that repeats the design, development, and testing steps as needed, based on feedback from users. This allows for continuous improvement of the software and ensures that the final product meets the user's needs. Extreme programming (A) and joint application design (D) also involve iterative development processes but are more specific methodologies that may not be suitable for all types of projects. Service-oriented architecture (C) is an architectural style for building distributed systems and is not a development methodology.

Question 7

During the _____ of the systems development life cycle (SDLC), an information system is operating, enhancements and modifications to the system have been developed and tested, and hardware and software components have been added or replaced.

Accepted Answer

The maintenance phase of the SDLC involves the ongoing operation of the system, including making enhancements, modifications, and updates to ensure the system continues to meet user needs and operates efficiently.

Question 8

_____ is the approach where an organization's team develops an information system internally. ​

Accepted Answer

Insourcing is the approach where an organization's team develops an information system internally. It involves using existing staff within the organization to design, develop, and implement the system, rather than outsourcing the work to a third-party vendor. Self-sourcing and crowdsourcing can also refer to the development of internal systems, but they are not commonly used terms in this context. Outsourcing is the opposite of insourcing, where the development of the system is entrusted to an external vendor.

Question 9

The end result of the_____ of the systems development life cycle (SDLC) model should give users and top management a clear view of what the problem is and how the information system will solve the problem. ​

Accepted Answer

The answer of The end result of the_____ of the...

Question 10

_____ is a method for developing software applications and information system projects in which a project is divided into smaller functions and developers cannot go on to the next phase until the current phase is finished.

Accepted Answer

Extreme programming (XP) is a software development methodology that emphasizes teamwork, customer satisfaction, and a rigorous process of continuous testing and revision. XP involves dividing the project into smaller functions, called stories, and developers cannot move on to the next phase until the current phase is completed. This approach helps to ensure that each stage of the project is completed thoroughly and accurately, reducing the risk of errors or oversights.

Question 11

A(n) _____ lists the completion time of a project on the x-axis and all the activities on the y-axis, which allows the systems analyst to monitor the progress of the project and detect any delay in the daily operation of the project. ​

Accepted Answer

A Gantt chart is a type of bar chart that visually displays the schedule of a project. It lists all the activities (or tasks) in the project on the y-axis and the completion time on the x-axis. The chart allows the systems analyst to monitor the project's progress and detect any delays in daily operations. The chart is useful for project planning and management, as it provides a clear overview of the project's schedule and its progress.

Question 12

One shortcoming of rapid application development (RAD) is _____.

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 13

Which of the following statements is true of extreme programming (XP)?

Accepted Answer

Extreme programming (XP) aims to improve the quality of a system by addressing major issues that may have been missed or not examined before. XP also promotes continuous testing and feedback, which helps to identify and address issues as early as possible in the development process. The other options are incorrect: A is incorrect because XP emphasizes completing one phase before moving on to the next; B is incorrect because XP encourages changes even after delivery to the users; and C is incorrect because XP promotes pair programming, where two developers work together at one workstation.

Question 14

Which of the following statements is true of pair programming?

Accepted Answer

Pair programming is a practice where two programmers work together on the same code at one workstation. They take turns in writing the code and reviewing it, offering suggestions and catching errors. It is a collaborative approach to programming that helps improve code quality and team communication.

Question 15

_____ refers to the trend of end users developing their own information systems with little or no formal assistance from an information systems team. ​

Accepted Answer

Self-sourcing refers to the trend of end users developing their own information systems with little or no formal assistance from an information systems team. Insourcing refers to performing a business function internally instead of relying on an external vendor, outsourcing refers to the practice of hiring external vendors to perform business functions, and crowdsourcing refers to obtaining services, ideas, or content by soliciting contributions from a large group of people, especially from an online community.

Question 16

_____ are small-scale versions of information systems, which are built before building the entire system, and are used to illustrate the system's benefits and allow users to offer feedback. ​

Accepted Answer

Prototypes are small-scale versions of information systems that are developed before the entire system is built. They are used to demonstrate the system's benefits and receive feedback from users. Structured systems refer to a specific approach to developing information systems, while flowcharts and context diagrams are tools used in the analysis phase of system development.

Question 17

Which of the following is a difference between the systems development life cycle (SDLC) and extreme programming (XP)?

Accepted Answer

The answer of Which of the following is a difference...

Question 18

A _____ is a tool used in the structured systems analysis and design (SSAD) model for data analysis. ​

Accepted Answer

Question 19

_____ is a philosophy and a software and system development methodology that focuses on the development, use, and reuse of small, self-contained blocks of codes to meet the software needs of an organization.

Accepted Answer

The philosophy and methodology described in the question is service-oriented architecture (SOA). SOA focuses on creating modular, reusable components (known as services) that can be combined and reused to meet the software needs of an organization. Extreme programming and rapid application development are both software development methodologies, but they do not specifically focus on the use of small, reusable code blocks. Joint application design is a collaborative software development process, but it is not directly related to the specific approach described in the question.

Question 20

Which of the following is a similarity between agile methodology and extreme programming (XP)?

Accepted Answer

Both agile methodology and extreme programming (XP) focus on an incremental development process, where software is developed in small, manageable increments, allowing for frequent reassessment and adaptation.
