CASE tools are typically used during the design phase of the SDLC, as they assist in creating diagrams, models, and other design artifacts. They may also be used during the implementation and maintenance phases, but their primary use is in the design phase.

Question 3

In the context of prototyping during the design phase of the systems development life cycle (SDLC),a _____ prototype shows users how a particular task that was not technically feasible or appears to be unfeasible can be done.

Accepted Answer

A proof-of-concept prototype is designed to demonstrate the feasibility of a particular concept or technology. It is used to show users how a particular task that was not technically feasible or appears to be unfeasible can be done. This type of prototype is useful in identifying technical risks and feasibility issues early on in the SDLC, and helps to guide the design and development of the final system.

Question 4

With the _____  outsourcing approach,an organization chooses an outsourcing company in a neighboring country,such as when a U.S.organization chooses a company in Canada or Mexico.

Accepted Answer

The term "nearshore" refers to outsourcing to a neighboring country, which is more geographically and culturally similar than a more distant offshore location. Therefore, the best choice is B.

Question 5

Which of the following approaches for developing information systems increases the risk of leaking confidential information to competitors?

Accepted Answer

Outsourcing involves sharing confidential information with a third-party vendor, which increases the risk of leaking confidential information to competitors. Therefore, outsourcing increases the risk of leaking confidential information to competitors.

Question 6

In _____ conversion of the implementation phase of the systems development life cycle (SDLC),an analyst introduces an information system in only a limited area of an organization,such as a division or department.

Accepted Answer

This type of introduction is known as a pilot conversion, where the system is introduced in a limited area within the organization to test its functionality and work out any kinks before a full-scale implementation occurs.

Question 7

Which is an outcome of the design phase of the systems development life cycle (SDLC)?

Accepted Answer

The design phase of the SDLC involves developing a detailed plan or blueprint for the system. This includes creating specifications for hardware, software, procedures, and network components that are required for the system to operate effectively. Therefore, option C is the correct answer as it provides specifications for executing the system. Option A refers to the requirements gathering phase, option B refers to the testing phase, and option D refers to the analysis phase of the SDLC.

Question 8

Question 9

In _____ conversion of the implementation phase of the systems development life cycle (SDLC),the old and new systems run simultaneously for a short time to ensure the new system works correctly.

Accepted Answer

In a parallel conversion, both the old and new systems run simultaneously for a short period to ensure that the new system works correctly before fully implementing it. This allows for a smooth transition and minimizes risks associated with a sudden changeover.

Question 10

In _____ conversion of the implementation phase of the systems development life cycle (SDLC),an old system is stopped and a new system is implemented.

Accepted Answer

The plunge conversion involves stopping the old system and completely implementing the new system. It is a risky and expensive approach, but it can be necessary if the old system is no longer functioning or if the implementation process is urgent. Parallel conversion involves running both the old and new systems simultaneously, Phased-in-phased-out conversion involves implementing the new system in phases while still using the old system, and Pilot conversion involves implementing the new system in a select area or department before rolling it out to the entire organization. None of these options involve completely stopping the old system during the implementation phase.

Question 11

Consider the following Program Evaluation Review Technique (PERT)network.
 The activities and their respective durations are given in the following table.
Which of the following paths of the given network is the critical path?

Accepted Answer

The answer of Consider the following Program Evaluation Review Technique...

Question 12

In _____ conversion of the implementation phase of the systems development life cycle (SDLC),as each module of a new system is converted,the corresponding part of an old system is retired.

Accepted Answer

Phased-in-phased-out conversion is the process of implementing a new system in phases while simultaneously retiring corresponding parts of the old system. This allows for a gradual transition to the new system while minimizing risk and disruption to business operations.

Question 13

Which statement is true of Critical Path Method (CPM)?

Accepted Answer

CPM is a project management method that helps in determining the activities critical to completing a project on time. It identifies the activities that cannot be delayed without delaying the project's overall completion date. Therefore, option B is correct. Option A is incorrect because activities on the critical path take the longest time to complete. Option C is also incorrect because activities on the critical path cannot be delayed without delaying the project. Option D is incorrect because a delay in the activities of a project affects the project's scheduled delivery.

Question 14

With the _____  outsourcing approach,an organization chooses an outsourcing company in any part of the world,as long as it can provide the needed services.

Accepted Answer

Offshore outsourcing is the best choice when an organization wants to get services from anywhere in the world. It is the most cost-effective option but comes with the challenge of managing cultural differences, time zone differences, and language barriers.

Question 15

_____ helps reduce the backlog in producing information systems and improve flexibility in responding to users' information needs.

Accepted Answer

Self-sourcing is a strategy in which end-users develop their own applications without the help of IT professionals. This helps to reduce the backlog in producing information systems and improve flexibility in responding to users' information needs since end-users can create their own solutions quickly without having to wait for IT departments to develop them. Intersourcing refers to the process of borrowing employees from different departments within the same company. Outsourcing is the practice of hiring an external company or individual to perform a business function. Crowdsourcing is the act of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, especially from the online community. While crowdsourcing can be used to obtain information and ideas, it is not a practical solution for reducing the backlog in producing information systems or improving flexibility in responding to users' information needs.

Question 16

With the _____  outsourcing approach,an organization chooses an outsourcing company in the same country.

Accepted Answer

The onshore outsourcing approach is the best choice because it involves choosing an outsourcing company in the same country as the organization. This approach provides several benefits such as reduced language and cultural barriers, easier communication, and increased control over the outsourcing process. Additionally, onshore outsourcing companies are generally more familiar with the legal and regulatory environment of the organization's home country, which can lead to smoother operations.

Question 17

During the implementation phase of the systems development life cycle (SDLC),_____.

Accepted Answer

During the implementation phase of the SDLC, the proposed solution is transformed from paper to action. A team configures the system and procures components for it. This phase involves building, testing, and installing the system into the production environment. Therefore, option D is the correct choice. Option A is part of the maintenance phase, option B is part of the analysis phase, and option C is part of the design phase.

Question 18

Which is a disadvantage of a request for proposal (RFP)?

Accepted Answer

The lengthy time frame for preparation can be a disadvantage of a request for proposal (RFP) as it can delay the procurement process and increase the overall cost. It can also discourage potential vendors from participating in the bidding process.

Question 19

In the context of information systems,which is an advantage of prototyping?

Accepted Answer

Prototyping allows for easier modification and adjustments to be made during the development process. This can save time and resources compared to having to make extensive changes to a complete system. However, it does not guarantee the success of the final system, nor does it require no support from top management. Additionally, a prototype may not always reflect the final system's actual operation since it may lack certain features or be simplified for testing purposes.
