Question 1

Traditionally,the most common option for packaged software was commercial off-the-shelf software.

Accepted Answer

This statement is true. Commercial off-the-shelf software (COTS) has traditionally been the most common option for packaged software.

Question 2

Which of the following is true of prototyping?
A) It is part of the fourth stage of the systems development life cycle.
B) It is synonymous with the adaptive maintenance of a system.
C) It does not consider user requirements for the system.
D) It uses a trial-and-error approach for discovering how a system should operate.
E) It is also known as end-user development.

Accepted Answer

Prototyping involves creating a preliminary version of a system to explore its functionality and gather feedback, often using a trial-and-error approach to refine how the system should operate. This method allows developers to understand user needs and system requirements more effectively.

The answer of Describe some methods of requirements collection during...

Question 8

Corrective maintenance involves making changes to an information system to evolve its functionality,to accommodate changing business needs,or to migrate it to a different operating environment.

Accepted Answer

Corrective maintenance is related to fixing problems or defects in an information system, not to making changes to evolve its functionality or accommodate business needs. This type of maintenance is called adaptive or perfective maintenance.

Question 9

Preventive maintenance of a system involves ________.
A) making changes to an information system to repair flaws in the design
B) making enhancements to improve processing performance or interface usability
C) making changes to a system to reduce the chance of future system failure
D) adding desired, but not necessarily required system features
E) making changes to an information system to accommodate changing business needs

Accepted Answer

Preventive maintenance involves making changes to reduce the chance of future system failure, rather than making repairs or enhancements. Options A, B, D, and E refer to corrective maintenance, adaptive maintenance, perfective maintenance, and perfective maintenance, respectively.

Question 10

The process of making changes to an information system to evolve its functionality,to accommodate changing business needs,or to migrate it to a different operating environment is known as ________ maintenance.
A) adaptive
B) perfective
C) preventive
D) corrective
E) predictive

Accepted Answer

Adaptive maintenance involves making changes to an information system in order to evolve its functionality, accommodate changing business needs or requirements, or migrate it to a different operating environment. This type of maintenance is necessary for an information system to stay current and to meet the changing needs of the business. Therefore, option A is the best choice.

Question 11

________ maintenance involves making enhancements to improve processing performance or interface usability or adding desired (but not necessarily required)system features (in other words,"bells and whistles").
A) Adaptive
B) Perfective
C) Preventive
D) Corrective
E) Predictive

Accepted Answer

Perfective maintenance is focused on improving the software's performance, usability, or adding new features that aren't necessary but are desirable.

Question 12

A company has a five-member team in charge of development and maintenance of its information systems.An information system is in place,and the team performs routine maintenance to keep it running smoothly.Which of the following scenarios is an example of adaptive maintenance?
A) Jason notices a faulty component in the system and modifies the component.
B) Justin works on the system to make the user interface more user-friendly.
C) Sara knows that the company is migrating to a new operating environment next month, and makes the appropriate changes to the system.
D) Dylan predicts that the company's old system may fail under new demands, and takes steps to avert it.
E) Kiera detects a fault in the coding, which is hampering system performance, and rectifies it.

Accepted Answer

Adaptive maintenance is the modification of a software system to keep it usable in a changing environment. Sara's actions of making changes to the system to ensure it works well after the migration to a new operating environment next month is a perfect example of adaptive maintenance. The other options can be categorized as corrective maintenance (A and E) or perfective maintenance (B and D).

Question 13

The process of making changes to an information system to repair flaws in design,coding,or implementation is known as ________ maintenance.
A) adaptive
B) perfective
C) preventive
D) corrective
E) predictive

Accepted Answer

Corrective maintenance is the process of making changes to an information system to repair flaws in design, coding, or implementation. It is focused on fixing errors and problems that have been identified in the system. Options A, B, C, and E refer to other types of maintenance that are focused on different objectives, such as improving functionality, preventing problems, or predicting future issues.

Question 14

Analysts interview people informed about the operation and issues of the current or proposed system.

Accepted Answer

Analysts typically conduct interviews with stakeholders who have knowledge and experience with the current or proposed system in order to gather information and insights for analysis and improvement recommendations.

Question 15

A company has a five-member team in charge of the development and maintenance of its information systems.An information system is in place,and the team performs routine maintenance to keep it running smoothly.Which of the following scenarios is an example of perfective maintenance?
A) Jason notices a faulty component in the system and modifies the component.
B) Justin works on the system to make the user interface more user-friendly.
C) Sara knows that the company is migrating to a different operating environment next month, and makes changes to the system.
D) Dylan predicts that the company's old system may fail under new demands, and takes steps to avert it.
E) Kiera detects a fault in the coding, which is hampering system performance, and rectifies it.

Accepted Answer

Perfective maintenance is focused on improving the functionality, maintainability, or usability of the system. Justin working on the user interface to make it more user-friendly is an example of perfective maintenance. Options A, C, D, and E are examples of corrective or adaptive maintenance, which are focused on fixing errors, bugs, or adapting the system to a different environment.

Question 16

The first phase of the systems development lifecycle is systems design.
