Question 1

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

Accepted Answer

Extreme programming (XP) focuses on frequent and immediate feedback from customers or end-users. This allows for quick adjustments and iterations, ensuring that the final product meets the needs of the customer.

Question 2

Identify a true statement of extreme programming.
A)Developers are allowed to go to the next phase before 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)System's quality is improved by addressing major issues that have not been examined before.

Accepted Answer

Extreme programming is an agile development methodology that prioritizes addressing major issues and risks early in the development process to improve the quality of the final product. The other statements are not true of extreme programming. In extreme programming, developers must complete one phase before moving on to the next phase, changes are allowed even after delivery to users, and two programmers work together at one workstation through a practice called pair programming.

Question 3

_________ 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 end users developing their own information systems without assistance from an information systems team. Insourcing refers to an organization using its own employees or resources to provide a service or product, while outsourcing refers to hiring an external company to provide a service or product. Crowdsourcing refers to obtaining ideas or information from a large group of people, typically via the internet.

Question 4

A)context diagram
B)feasibility study
C)conceptual data model
D)flowchart

Accepted Answer

A feasibility study is conducted by analysts to determine the practicality and viability of a proposed solution. This involves analyzing different aspects such as technical, economic, operational, and legal feasibility. The goal of a feasibility study is to provide decision-makers with the information necessary to determine whether or not to proceed with the project and to obtain funding for it. Therefore, a feasibility study is a common tool used by analysts during the SDLC. Options A, C, and D are also commonly used tools during the SDLC, but they are not specifically aimed at investigating a proposed solution's viability and obtaining funding.

Question 9

Identify a similarity between agile methodology and extreme programming (XP).
A)Both give more 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 one time.

Accepted Answer

Both agile methodology and extreme programming (XP) focus on an incremental development process where software is developed incrementally, with each iteration of development building upon the previous one. This allows for flexibility and adaptation to changing needs. While both methods do emphasize team coding, and XP does have programmers perform different actions at once, these are not similarities unique to these two methods.

Question 10

_________ 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 (RAD)
B)Extreme Programming (XP)
C)Service-Oriented Architecture (SOA)
D)Systems development life cycle (SDLC)

Accepted Answer

Systems development life cycle (SDLC) is a methodology that provides a structured and organized approach for developing an information system or project. It consists of well-defined phases such as planning, analysis, design, implementation, and maintenance that are performed in sequence. This helps ensure that the system is delivered on time, within budget, and meets the client's requirements. RAD, XP, and SOA are all development approaches or architectures that can be used within the SDLC framework.

Question 11

_________ 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 an organization.
A)proof-of-concept
B)self-sourcing
C)selling
D)phased-in-phased-out

Accepted Answer

Selling prototypes are specifically designed to showcase the features and potential benefits of a proposed system to users and management, aiming to gain their support and approval.

Question 12

The fundamental principle behind _________ is that the "blocks of codes" can be reused in a variety of different applications,allowing new business processes to be created from a pool of existing services.
A)structured systems analysis and design (SSAD)
B)joint application design (JAD)
C)service-oriented architecture (SOA)
D)computer-aided systems engineering (CASE)

Accepted Answer

The principle described in the question, where blocks of code can be reused to create new applications, is a fundamental concept of service-oriented architecture (SOA). SOA allows businesses to create new processes from existing services, making it a scalable and adaptable technology. Structured systems analysis and design (SSAD), joint application design (JAD), and computer-aided systems engineering (CASE) are all methodologies or tools for designing and developing software systems but do not specifically focus on service reuse in the same way as SOA.

Question 13

_________ is a tool used in the structured systems analysis and design (SSAD)model for data analysis.
A)conceptual data model
B)context diagram
C)flowchart
D)data flow diagram

Accepted Answer

A conceptual data model is a tool used in the structured systems analysis and design (SSAD) model for data analysis. It is a graphical representation of the data entities and their relationships within a system.

Question 14

Identify a difference between the systems development life cycle (SDLC)and extreme programming (XP).
A)Systems development life cycle (SDLC)have a planning and analysis phase,whereas extreme programming (XP)combines both the phases into one phase.
B)Developers following a systems development life cycle (SDLC)can move to any phase from the current phase,whereas in extreme programming (XP)developers cannot go on to the next phase until;the current phase is finished.
C)In the systems development life cycle (SDLC)changes cannot be made to the system once it is delivered to the user,whereas extreme programming (XP)method delivers the system to the users and then make changes suggested by the user.
D)Systems development life cycle (SDLC)develops the entire system at once,whereas extreme programming (XP)uses incremental steps to improve an information system's quality.

Accepted Answer

The main difference between the SDLC and XP is that SDLC develops the entire system at once, while XP uses incremental steps to improve the system's quality. Option A is incorrect as both methods go through analysis and planning stages but SDLC has it as a separate phase. Option B is incorrect as XP allows developers to move to the next phase without completing the current phase. Option C is incorrect as SDLC does allow for changes to be made to the system post-delivery, but with a formal change control process in place.

Question 15

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 (JAD)
B)structured systems analysis and design (SSAD)
C)object-oriented
D)class-responsibility collaboration

Accepted Answer

The structured systems analysis and design (SSAD) approach treats process and data independently and requires completing the analysis before beginning the design of information systems. JAD, object-oriented, and class-responsibility collaboration approaches do not necessarily require a sequential process and may not treat process and data independently.

Question 16

The end result of the _________ phase of the systems development life cycle (SDLC)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 solve it, providing a clear view for users and management.

Question 17

One shortcoming of rapid application development (RAD)is _____.
A)a narrow focus,which might limit future development
B)that building an application takes more time
C)a lack of reusability of small,self-contained blocks of codes
D)a set plan,where they do not respond to the changing needs

Accepted Answer

RAD emphasizes quick development and prototyping, which may result in a narrowly focused solution that does not provide the flexibility for future expansion or changes.

Question 18

A _________ is a written document with detailed specifications that is used to appeal bids for equipment,supplies,or services from vendors.
A)statistical information
B)request for proposal (RFP)
C)cost-benefit analysis (CBA)report
D)milestone chart

Accepted Answer

A request for proposal (RFP) is a document used to solicit bids from vendors for equipment, supplies, or services. It includes detailed specifications and requirements for the items or services being requested. A cost-benefit analysis (CBA) report evaluates the costs and benefits of a proposed project or investment. Statistical information and milestone charts can be used to track progress or analyze data, but they are not typically used to request bids from vendors.
