Question 1

The creation of a design prototype that is not a working information system, but represents a part of the system that needs additional refinement happens with the prototyping methodology.

Accepted Answer

The answer of The creation of a design prototype that...

Question 2

Agile development is considered a special case of RAD approach to developing systems.

Accepted Answer

The answer of Agile development is considered a special case...

Question 3

The primary advantage of the Waterfall Development methodology is requirements are completely specified and held relatively constant prior to programming.

Accepted Answer

In the Waterfall model, each phase must be completed before the next phase can begin. Requirements are defined and fixed before development begins, ensuring that changes are minimized during the development process, making it difficult and costly to implement changes once the project is in its final stages.

Question 4

An analyst that focuses on the IS issues in a system, and who represents the interests of the IS department is called a systems analyst.

Accepted Answer

A systems analyst is responsible for analyzing the IS (information systems) issues in a system and representing the interests of the IS department.

Question 5

Systems analysts Lori and Mark are employed by the local hospital. They have been assigned to develop a very complex patient monitoring system for the cardio-care unit using a new display technology. Throwaway prototyping is a very suitable methodology for this project.

Accepted Answer

Throwaway prototyping is a good choice for projects where requirements are not well understood or where the technology being used is new and untested. In this case, the project involves a new display technology and a complex patient monitoring system, which suggests that requirements may not be fully understood. Therefore, throwaway prototyping could be a suitable methodology for this project.

Question 6

Scott has been assigned to focus on the users during the upcoming information systems installation. Scott will provide user training and documentation. His role is to serve as a change management analyst.

Accepted Answer

The statement describes Scott's role as a change management analyst responsible for user training and documentation during the information systems installation.

Question 7

The analyst that develops ideas and suggestions to improve the application of information technology is commonly called a systems analyst.

Accepted Answer

This statement is true. The role of a systems analyst is to analyze business processes and information systems, and develop recommendations for how to improve the use of technology within an organization.

Question 8

An analyst with business skills that understands the business issues surrounding a system is commonly called a project manager.

Accepted Answer

While project managers may possess business skills, their primary role is to manage the project, including planning, organizing, and overseeing the work of the team members. An analyst with business skills who understands the business issues would be more accurately referred to as a business analyst.

Question 9

Phased development is considered a special case of RAD approach to developing systems.

Accepted Answer

Phased development involves dividing a project into distinct phases, each of which builds on the previous phase's achievements. This is a characteristic of the RAD approach, which emphasizes a flexible approach to development, rapid prototyping, and client involvement.

Question 10

An analyst that focuses on the technical issues of the organization (hardware, software, databases and networks) is commonly called a change management analyst.

Accepted Answer

A change management analyst focuses on managing changes within an organization, including changes to processes and procedures, not just technical issues. A technical analyst may focus more specifically on hardware, software, databases, and networks.

Question 11

Parallel development relies on only one iteration of the analysis phase.

Accepted Answer

Parallel development involves multiple iterations of the analysis phase, as each team works independently on their assigned modules.

Question 12

Extreme programming is founded on core principles such as communication, simplicity, feedback, and courage

Accepted Answer

Extreme programming (XP) is based on the principles of communication, simplicity, feedback, and courage, which are essential for successful software development. These principles promote team collaboration, continuous improvement, and customer satisfaction.

Question 13

Determining who will use the system, what the system will do, and where and when it will be used is performed during the analysis phase of the SDLC.

Accepted Answer

The analysis phase of the SDLC involves identifying the users of the system, the system's functions and features, and the context in which the system will be used. This helps to establish the requirements for the system and inform the design and development phases.

Question 14

Kim repeatedly performs the analysis, design, and implementation phases concurrently in a cycle until the system is completed. She then goes back and from scratch does a thorough design and implementation to complete the project. She is following a throwaway prototype methodology.

Accepted Answer

The description matches the characteristics of a throwaway prototype methodology, where the analysis, design, and implementation phases are performed iteratively until the final system is developed. Afterwards, a more thorough design and implementation are undertaken to recreate the system from scratch.

Question 15

Michelle has been assigned the task of completing the project in a timely manner and within budget. Her project team role is infrastructure analyst.

Accepted Answer

Michelle's role as an infrastructure analyst typically involves analyzing and improving the IT infrastructure within an organization, not managing projects or budgets directly. Project completion within time and budget constraints is usually the responsibility of a project manager or project lead.

Question 16

A local retailer has hired Geneva and Sydney to develop his new information system. He is not sure what type of system he wants, but it must be completed in four months and he needs to know regularly that the project is on schedule. Geneva and Sydney should use the Waterfall Development methodology for constructing the system.

Accepted Answer

The Waterfall Development methodology is less flexible and does not easily accommodate changes or the need for frequent updates on progress. Agile methodology would be better suited for this scenario, as it allows for more flexibility, regular updates, and adjustments throughout the development process.

Question 17

Extreme programming is ideal for developing large mission-critical applications.

Accepted Answer

Extreme programming, though suitable for software development, may not be the best approach for large mission-critical applications. More structured and controlled development methodologies, such as Waterfall or Agile, may be a better fit for such applications.

Question 18

Agile development methodology aims at eliminating the modeling and documentation overhead in IS projects, while emphasizing simple, iterative application development.

Accepted Answer

The statement accurately describes the aim of agile development methodology.

Question 19

RAD (Rapid Application Development) adjusts the SDLC phases to get some of the system developed and into the hands of the users quickly.

Accepted Answer

RAD is a development methodology that emphasizes rapid prototyping and quick feedback from users to accelerate the SDLC and get a working prototype of the system in the hands of end-users quickly. This allows for early identification of issues and promotes constant iteration and improvement of the system.

Question 20

Throwaway prototyping balances the benefits of well-thought-out analysis and design phases with the advantages of using prototypes to refine key issues before the system is built.

Accepted Answer

Throwaway prototyping involves creating prototypes that are not meant to be part of the final system, but rather used to identify and refine key issues before building the actual system. This approach allows for both analysis and design to be well thought-out, while also allowing for early feedback through the use of prototypes.
