Accepted Answer

The answer of Which is a difference between the systems...

Question 2

A _____ is a written document with detailed specifications that is used to request bids for equipment,supplies,or services from vendors.
A)bill of materials
B)request for proposal
C)cost-benefit analysis report
D)milestone chart

Accepted Answer

A request for proposal (RFP) is a formal document that outlines the exact requirements of a project or order and invites vendors to submit bids for it. A bill of materials lists all the items, parts, assemblies, and sub-assemblies required to manufacture or build a product. A cost-benefit analysis report is a study that compares the potential costs and benefits of different projects, investments, or business decisions. A milestone chart is a visual representation of a project's progress, showing key dates and deliverables.

Question 3

Which statement is true of extreme programming (XP)?
A)Developers are allowed to go to the next phase before the completion of the current phase.
B)This method does not allow changes to a system after its delivery to the users.
C)Two programmers perform activities different from the other at different workstations.
D)A system's quality is improved by addressing major issues that have not been examined before.

Accepted Answer

Extreme Programming (XP) is a software development methodology that emphasizes teamwork, frequent feedback, continuous testing, and continuous planning. It focuses on improving a system's quality by addressing major issues that have not been examined before, such as integration problems, inadequate testing, and complex requirements. Therefore, option D is the correct choice. The other options are incorrect because XP requires developers to complete one phase before moving to the next (option A), allows changes to a system even after its delivery to users (option B), and relies on pair programming, where two developers work on the same task at one workstation (option C).

Question 4

Which is a similarity between agile methodology and extreme programming (XP)?
A)Both give equal emphasis to team coding.
B)Both focus on an incremental development process.
C)Both respond to changing needs before the system is delivered.
D)Both have programmers perform different actions at the same time.

Accepted Answer

Both Agile methodology and XP follow an incremental development process where the product is developed in small increments or iterations, and each iteration consists of planning, designing, coding, testing, and delivering a working software product. This approach helps to respond quickly to changing requirements and user feedback. Although both methods may emphasize team collaboration, XP places more emphasis on team coding and practices like pair programming. While both methods may have developers performing different actions simultaneously, this is not a defining or significant similarity between them.

Question 5

The end result of the _____  phase 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.
A)planning
B)requirements-gathering 
C)design
D)implementation

Accepted Answer

The planning phase of the SDLC involves identifying the problem and determining how an information system can address it, providing a clear view to users and management.

Question 6

Which of the following statements is true of pair programming?
A)Two programmers work on different codes at one workstation.
B)Two programmers work on the same code at one workstation.
C)Two programmers perform same activities at different workstations.
D)Two programmers perform different activities at different workstations.

Accepted Answer

Pair programming is a technique in which two programmers work together on the same code at one workstation. They take turns typing and reviewing code, discussing ideas and design decisions, and catching errors. It is a collaborative approach that can lead to higher code quality and knowledge sharing.

Question 7

_____ 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.
A)Structured systems
B)Prototypes
C)Flowcharts
D)Context diagrams

Accepted Answer

Prototypes are small-scale versions of information systems that are built before building the entire system. They are used to illustrate the system's benefits and allow users to offer feedback.

Question 8

_____ 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.
A)Extreme programming
B)Rapid application development
C)Service-oriented architecture
D)Joint application design

Accepted Answer

Extreme programming is a software development methodology that focuses on incremental development and continuous feedback. It requires developers to complete one phase or function of the project before moving on to the next phase. This allows for the previous phase to be fully tested and validated before proceeding, which can result in higher quality software.

Question 9

_____ uses an iterative process that repeats the design,development,and testing steps as needed,based on feedback from users.
A)Extreme programming
B)Rapid application development
C)Service-oriented architecture
D)Joint application design

Accepted Answer

The answer of _____ uses an iterative process that repeats...

Question 10

Which 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

One of the key features of extreme programming (XP) is the emphasis on immediate feedback from users. This means that users are involved throughout the development process and are able to provide feedback on the product as it is being developed. This allows for faster iterations and a better end product. While some of the other options (A, B, D) may be important in certain contexts, they are not key features of XP specifically.

Question 11

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

Accepted Answer

Structured systems analysis and design (SSAD) follows a systematic and step-by-step approach, treating process and data independently. It is a sequential approach that completes the analysis before beginning the design of information systems. Joint Application Design (JAD) is a group-based approach that emphasizes the participation of system analysts, users, managers, and stakeholders in the design and development process. Object-oriented and class-responsibility collaboration are both design methodologies that focus on objects and their interactions rather than processes and data, and they do not strictly require completing analysis before design.

Question 12

_____ 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

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 the practice of using an organization's own personnel or resources to accomplish a task, while outsourcing refers to the practice of hiring a third-party vendor to handle certain tasks. Crowdsourcing is the practice of obtaining information or services by soliciting contributions from a large group of people, typically via the internet.

Question 13

_____ 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.
A)Extreme programming
B)Rapid application development
C)Service-oriented architecture
D)Joint application design

Accepted Answer

The description given in the question refers to service-oriented architecture (SOA). SOA involves the development and reuse of small, self-contained units of code called services, which can be combined to create larger applications. Extreme programming and rapid application development are both development methodologies that focus on iterative development and quick turnaround, but they do not specifically emphasize the use and reuse of small code blocks. Joint application design is a collaborative design process that involves stakeholders in the development process, but it is not focused on code reuse.

Question 14

_____ 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

Accepted Answer

Selling prototypes are used to market a proposed system to users and management by showcasing some of its features and demonstrating its potential benefits to the organization.

Question 16

_____ is the approach where an organization's team develops an information system internally.
A)Insourcing
B)Outsourcing
C)Self-sourcing
D)Crowdsourcing

Accepted Answer

Insourcing refers to the practice of developing an information system internally by the organization's own team, rather than outsourcing or buying an off-the-shelf system from an external vendor.

Question 17

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 18

_____ is a series of well-defined phases performed in sequence that serves as a framework for developing an information system or project.
A)Rapid Application Development
B)Extreme Programming
C)The maintenance process model
D)The systems development life cycle

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. The SDLC includes phases such as planning, analysis, design, implementation, and maintenance. Rapid Application Development (RAD) and Extreme Programming (XP) are both development methodologies that can be used within the SDLC, but they do not encompass the entire framework. The maintenance process model is a separate model focused on maintaining already developed systems.

Question 19

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.
A)planning
B)design 
C)implementation
D)maintenance

Accepted Answer

The maintenance phase of SDLC involves operating an already developed and tested information system, making modifications, adding or replacing hardware/software components as needed to ensure that it continues to fulfill its intended purpose.

Question 20

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.
A)work breakdown structure
B)event chain diagram
C)Gantt chart
D)risk register

Accepted Answer

A Gantt chart is a tool used for scheduling and monitoring project progress. It lists the various project activities on the y-axis and the timeline for the completion of those activities on the x-axis. This allows the systems analyst to track progress, identify potential delays, and make adjustments to meet the project goals. Work breakdown structure is a method of dividing complex tasks into smaller, more manageable components. Event chain diagram is a tool used to identify potential events or risks that could impact a project's progress. Risk register is a document used to record and track potential risks associated with a project. While each of these tools can be useful in project management, the Gantt chart is the best choice for monitoring project progress and identifying delays.
