A cutover conversion strategy is characterized as risky because it involves transitioning from an old system to a new one in a single, abrupt switch. This approach carries a higher level of risk as it leaves little room for error or fallback options. Any issues or problems that arise during the conversion can have significant consequences on the operation and functionality of the new system. Therefore, it is important to carefully plan and execute a cutover conversion strategy to mitigate potential risks and ensure a smooth transition.Rate this question:

The percentage of resources devoted to the maintenance of a system:
- A.
Generally increases over time.
- B.
Generally decreases over time.
- C.
Generally stays about the same over time.
- D.
Is variable depending on the system.
Correct Answer
A. Generally increases over time.Explanation
The percentage of resources devoted to the maintenance of a system generally increases over time. This is because as a system ages, it becomes more prone to issues and requires more frequent repairs and updates. Additionally, as technology advances, new features and functionalities are introduced, which require additional maintenance efforts. As a result, the proportion of resources allocated to maintenance gradually increases to ensure the system's smooth operation and to address any potential problems that may arise.Rate this question:

Which of the following best describes a responsibility of a systems analyst?
- A.
Ensure the promised benefits of a system are achieved
- B.
Develop detailed system requirements
- C.
Train users
- D.
All of the above
Correct Answer
B. Develop detailed system requirementsExplanation
A responsibility of a systems analyst is to develop detailed system requirements. This involves gathering and analyzing information from users and stakeholders to understand their needs and translate them into specific technical specifications for the system. By doing so, the systems analyst ensures that the system is designed and developed according to the desired functionality and objectives. This step is crucial in the system development life cycle as it lays the foundation for successful system implementation and helps in achieving the desired outcomes.Rate this question:

Which prototyping step is not the responsibility of the system builders?
- A.
Develop initial prototype
- B.
Use prototype and note desired changes
- C.
Revise and enhance prototype
- D.
Assist with converting the prototype to an operational system
Correct Answer
B. Use prototype and note desired changesExplanation
The system builders are responsible for developing the initial prototype, revising and enhancing the prototype, and assisting with converting the prototype to an operational system. However, the step of using the prototype and noting desired changes is not their responsibility. This step typically involves the end-users or stakeholders who test the prototype and provide feedback on any necessary modifications or improvements.Rate this question:

Which of the following is not an advantage of prototyping?
- A.
Only basic system requirements are needed at the front-end of the project.
- B.
End-prototype typically has more security and control features than a system developed with an SDLC process.
- C.
Strong top-down commitment may be less necessary at the outset of the project.
- D.
User acceptance is likely to be higher than with a system developed using an SDLC process.
Correct Answer
B. End-prototype typically has more security and control features than a system developed with an SDLC process.Explanation
Prototyping is a development approach that involves creating a working model of a system before fully developing it. One advantage of prototyping is that only basic system requirements are needed at the front-end of the project, allowing for flexibility and adaptability during the development process. Another advantage is that strong top-down commitment may be less necessary at the outset of the project, as prototyping allows for iterative feedback and adjustments. Additionally, user acceptance is likely to be higher with prototyping compared to a system developed using a traditional SDLC process. However, the given statement suggests that an end-prototype typically has more security and control features than a system developed with an SDLC process, which is not an advantage of prototyping.Rate this question:

Which of the following is typical for a pure prototyping approach?
- A.
Firms use the approach to explore the use of newer technologies.
- B.
Documentation is less complete than with traditional systems development approaches.
- C.
Less security and control features are incorporated than with traditional SDLC approach.
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
A pure prototyping approach is typically characterized by firms using it to explore the use of newer technologies. In this approach, documentation is less complete compared to traditional systems development approaches. Additionally, less emphasis is placed on incorporating security and control features compared to the traditional SDLC approach. Therefore, the correct answer is "all of the above."Rate this question:
