Accepted Answer

The planning phase in the SDLC involves investigating the feasibility of a proposed solution and determining how best to present it to management to obtain funding. During the planning phase, analysts identify project scope, objectives, and deliverables, as well as collect information on feasibility, costs, and resources required for the project. Therefore, option C is the correct answer.

Question 5

_____ is one of the most common cost-effectiveness analysis methods.

Accepted Answer

Net present value (NPV) is one of the most commonly used cost-effectiveness analysis methods. This method involves comparing the present value of the costs of a project or investment to the present value of its benefits, taking into account the time value of money. The main advantage of NPV analysis is that it provides a more accurate measure of the true economic value of a project or investment, as it considers both the costs and benefits of the investment and discounts them to their present value.

Question 6

During the _____  phase of the systems development life cycle (SDLC),analysts choose the solution that is the most realistic and offers the highest payoff for the organization.

Accepted Answer

During the design phase of the SDLC, analysts create a detailed solution to the problem identified in the analysis phase. They evaluate different technical solutions and choose the one that is the most realistic and offers the highest payoff for the organization. Therefore, the best choice is option C - design.

Question 7

In the context of structured systems analysis and design (SSAD)models,a _____ is a tool that helps analysts understand the data requirements an information system must meet by defining data elements and showing the associations between them.

Accepted Answer

A conceptual data model is specifically designed to define data elements and show the associations between them. Data flow diagrams and flowcharts are more focused on the flow of data and processes within a system, and a context diagram shows the interactions between a system and its external entities.

Question 8

In the _____ phase of the systems development life cycle (SDLC),a problem is defined and alternatives are generated for solving it.

Accepted Answer

The requirements-gathering and analysis phase is where the problem is defined and alternatives are generated for solving it. The planning phase is focused on identifying the scope and feasibility of the project. The designing and prototype-development phase is where the chosen solution is designed and tested. The implementation phase is where the final solution is deployed and maintained.

Question 9

Which is a characteristic of joint application design (JAD)?

Accepted Answer

Joint application design (JAD) is a collaborative approach that involves users and system professionals in a structured workshop to design or develop an application. This approach helps to ensure that the requirements gathered are multi-dimensional in focus, and that the end product meets the needs of all stakeholders. Option A is incorrect because JAD focuses on multi-dimensional requirements, not one-dimensional requirements. Option C is incorrect because JAD is a collaborative process that involves both users and system professionals.

Question 10

The _____ document,created during the requirements-gathering and analysis phase of the systems development life cycle (SDLC),indicates the end of the analysis phase and the start of the design phase.

Accepted Answer

The system specifications document is created during the requirements-gathering and analysis phase of the SDLC, and it outlines the specific requirements and features of the system being developed. Once this document is complete, it marks the end of the analysis phase and the start of the design phase of the SDLC. The maintenance plan, blueprint, and execution are not directly related to this phase transition.

Question 11

_____ feasibility is concerned with issues such as political repercussions of using an information system and meeting the requirements of the Information Privacy Act.

Accepted Answer

Legal feasibility refers to whether the proposed system conforms to the legal requirements such as Information Privacy Acts, copyright laws, and other regulations. It also considers the political implications of implementing the system, such as how it might affect the relationships between different stakeholders involved.

Question 12

_____ feasibility is the measure of how well a proposed solution will work in an organization and how internal and external customers will react to it.

Accepted Answer

Operational feasibility considers the practicality and usability of a proposed solution within the operations and culture of an organization, as well as the satisfaction of its customers. Economic feasibility considers the financial costs and benefits, technical feasibility considers the technical requirements and constraints, and legal feasibility considers the legal and regulatory requirements and risks.

Question 13

In the design phase of the systems development life cycle (SDLC),the _____ design is an overview of the system and does not include hardware or software choices.

Accepted Answer

The conceptual design in the design phase of the SDLC is a high-level overview of the system and does not involve specific hardware or software choices. It focuses on the system's functionality and the user's needs. The other options, virtual and physical designs, involve more detailed specifications and choices about hardware and software components. The logical design involves the creation of a data flow model and data dictionary, and may also include some software and hardware choices.

Question 14

Which benefit of an information system is categorized as a tangible?

Accepted Answer

Increased company profits are considered tangible benefits as they are directly measurable in monetary terms.

Question 15

In the context of structured systems analysis and design (SSAD)models,a _____ is a tool that illustrates the logical steps in a process but does not show data elements and associations.

Accepted Answer

A flowchart is a tool that illustrates the logical steps in a process, but it does not show data elements and associations. Data flow diagrams, on the other hand, do show data elements and associations. A context diagram is a high-level overview of a system that shows only the main processes and their inputs/outputs. A conceptual data model shows the major entities and relationships involved in a system, but it does not show the specific attributes or data elements of each entity.

Question 16

Which is a common cost-effectiveness analysis method?

Accepted Answer

Internal rate of return (IRR) is a common cost-effectiveness analysis method that measures the profitability of an investment. It calculates the discount rate at which the present value of the cash inflows equals the initial cost of the investment.
