Question 1

_____ are employees who will use an information system regularly and can offer important feedback on the system's strengths and weaknesses.

Accepted Answer

Internal users are employees who work within the organization and will use the information system regularly. They can provide important feedback on the system's strengths and weaknesses since they are directly affected by it. Merchandise users, suppliers, and contractors may not necessarily use the information system regularly and may not have as much insight into its performance.

Question 2

In the context of the planning phase of the systems development life cycle (SDLC), which of the following is an example of an internally identified problem in information systems?

Accepted Answer

Management voicing concern about the organization's lack of a competitive edge in the marketplace is an internally identified problem as it originates from within the organization itself.

Question 3

Service-oriented architecture (SOA) advocates that core business functions and the dynamic functions that change all the time should be decoupled.

Accepted Answer

SOA philosophy emphasizes the need for decoupling core business functions from dynamic functions. This approach enables greater flexibility, scalability, and adaptivity in the organization's IT systems.

Question 4

External users are normally part of a company's task force.

Accepted Answer

External users are not part of the company, they are individuals or organizations outside of the company who have an interest in its financial information, such as investors, creditors, customers, and government agencies.

Question 5

Normally, a task force for the planning phase of the systems development life cycle (SDLC) includes only representatives from the IT department and the top management.

Accepted Answer

A task force for the planning phase of the SDLC should include representatives from different departments like finance, operations, and marketing along with the IT department and top management. This ensures that the final product meets the needs and requirements of all stakeholders involved in the project.

Question 6

Information system projects are often an extension of existing systems or involve replacing an old technology with a new one.

Accepted Answer

Information system projects often involve upgrading or replacing existing systems in order to improve efficiency, functionality, and/or user experience. It is rare for a project to involve completely starting from scratch with no prior system in place.

Question 7

In phased-in-phased-out conversion of the implementation phase of the systems development life cycle (SDLC), an analyst introduces a new information system in only a limited area of an organization.

Accepted Answer

The answer of In phased-in-phased-out conversion of the implementation phase...

Question 8

The object-oriented approach to the analysis and design of information systems treats process and data independently and is a sequential approach that requires completing the analysis before beginning the design.

Accepted Answer

The object-oriented approach integrates both process and data, focusing on objects that encapsulate both data and behavior, and it allows for iterative development where analysis and design can occur concurrently.

Question 9

Creating a help desk to support users is an important task in the implementation phase of the systems development life cycle (SDLC).

Accepted Answer

The answer of Creating a help desk to support users...

Question 10

Establishing evaluation criteria often gives rise to subjectivity issues during the systems development life cycle (SDLC) process.

Accepted Answer

The answer of Establishing evaluation criteria often gives rise to...

Question 11

During the planning phase of the systems development life cycle (SDLC), a systems designer must define the symptoms rather than the underlying problem.

Accepted Answer

During the planning phase of the SDLC, a systems designer must define the underlying problem rather than simply the symptoms. This involves conducting a thorough analysis of the current system and identifying areas for improvement or potential issues that need to be addressed in the new system design. Defining only the symptoms would not address the root cause of the problem and could lead to ineffective solutions.

Question 12

During the _____ of the systems development life cycle (SDLC) model, an information systems designer must define the problem an organization faces, taking care not to define symptoms rather than the underlying problem.

Accepted Answer

The answer of During the _____ of the systems development...

Question 13

The systems development life cycle (SDLC) model is appropriate in situations when the problem under investigation is not well defined.

Accepted Answer

The SDLC model is best suited for projects with well-defined requirements and objectives, as it relies on a structured and sequential approach to software development.

Question 14

The systems development life cycle (SDLC) is also known as the _____.

Accepted Answer

The SDLC is commonly referred to as the waterfall model, which is a linear sequential approach to software development. The other options (A, B, and C) are not equivalent or commonly used terms for the SDLC.

Question 15

While using PERT (Program Evaluation Review Technique) and CPM (Critical Path Method) techniques, activities that are on the critical path are more flexible than those activities which are not on the critical path.

Accepted Answer

Activities on the critical path are not flexible as any delay in those activities will result in a delay in the overall project completion time. Non-critical path activities may have some flexibility in their timing without affecting the overall project timeline.

Question 16

Users and top management should not be included in the construction phase of a prototype because construction is purely a technical matter.

Accepted Answer

Users and top management should be involved in the construction phase of a prototype because their input and feedback help ensure that the prototype meets their needs and expectations. The construction phase is not purely a technical matter but also needs to consider usability, functionality, and user experience.

Question 17

The creation of a system specifications document indicates the beginning of the analysis phase of the systems development life cycle (SDLC).

Accepted Answer

The creation of a system specifications document actually marks the beginning of the design phase of the SDLC, not the analysis phase. The analysis phase focuses on understanding and documenting the business needs and requirements.

Question 18

In the context of the planning phase of the systems development life cycle (SDLC), which of the following is an example of an externally identified problem?

Accepted Answer

An externally identified problem is one that is identified by stakeholders outside of the organization. In this case, suppliers have identified inefficiencies in the inventory control procedure, making it an externally identified problem. The other options are either internal problems or solutions to problems rather than problems themselves.

Question 19

It is important to project an organization's growth rate when designing information systems.

Accepted Answer

Projecting an organization's growth rate is important when designing information systems because it helps to ensure that the system can accommodate future growth and expansion. Without considering future growth, the system may quickly become outdated and unable to meet the organization's needs.

Question 20

One of the advantages of prototyping is that modifying a prototype is easier than modifying a complete system.

Accepted Answer

Prototyping allows for easier and less costly modifications early in the development process, compared to making changes after a complete system has been developed.
