Question 1

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 2

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

Accepted Answer

SOA promotes loose coupling between core business functions and dynamic functions to enable agility and flexibility in responding to changing business requirements.

Question 3

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.

Question 4

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 5

In the context of structured systems analysis and design (SSAD) models, a _____ is a tool that shows a process at a more general level and is helpful for showing top management and the task force how a process works.
A) data flow diagram
B) flowchart
C) context diagram
D) conceptual data model

Accepted Answer

A context diagram is a high-level overview of a system or process, showing the inputs, outputs, and interactions with external entities. It is useful for presenting information to top management and the task force in a simplified way. Data flow diagrams and flowcharts are more detailed tools used to represent processes at a lower level. A conceptual data model is a tool used to represent the underlying data structure of a system.

Question 6

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 ideally include representatives from various departments and stakeholders such as end-users, business analysts, project managers, and subject matter experts along with IT and top management. This ensures a comprehensive understanding of business needs and requirements and improves the chances of successful project delivery.

Question 7

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 included in the construction phase of a prototype because they can provide valuable feedback and insights on the usability and functionality of the prototype. This can help ensure that the final product meets the needs and expectations of the users and aligns with the goals of the organization.

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 answer of The object-oriented approach to the analysis and...

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

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 identify and understand the underlying problem rather than just the symptoms. Only by identifying the root cause of the problem can an effective solution be developed.

Question 11

A__________is a written document with detailed specifications that is used to appeal bids for equipment, supplies, or services from vendors.
A) bill of materials
B) request for proposal
C) cost-benefit analysis report
D) milestone chart
E) Select

Accepted Answer

A request for proposal (RFP) is a written document that specifies the requirements for equipment, supplies, or services, and is used to solicit bids or proposals from vendors. It outlines the objectives and scope of the project, as well as the desired features, performance standards, and other criteria that must be met. The RFP helps ensure that vendors understand the requirements and can provide accurate and competitive bids for the project.

Question 12

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

Accepted Answer

It is important to project an organization's growth rate when designing information systems because it helps in ensuring that the information systems can accommodate the organization's future needs and scale with its growth. This can include factors such as increased data volume, user base, and business processes. Failing to consider growth can result in inadequate systems that become outdated quickly or require significant resources to upgrade or replace.

Question 13

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 are often developed to enhance or extend existing systems or to replace outdated technologies with new ones. It's rare for information system projects to be completely new or developed from scratch without any tie to existing systems or technologies.

Question 14

In the extreme programming environment,__________allows programmers to detect and correct programming mistakes as they go, which is faster than correcting them after an entire program has been written.
A) procedural programming
B) pair programming
C) sequential programming
D) parallel programming
E) Select

Accepted Answer

Pair programming is a practice in extreme programming where two programmers work together on one computer. This allows for continuous code review and detection and correction of programming mistakes as they happen, which is faster and more efficient than waiting until the entire program is written.

Question 15

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 16

Which of the following is an outcome of the design phase of the systems development life cycle (SDLC)?
A) A document that contains the requirements for the current system to determine its main problem
B) A document that contains operation-specific data collected by the analysts after observing the system's performance over a predefined period of time
C) A document with exact specifications for executing the system, including procedures, hardware and software, and networking components
D) A document that drafts the details noted after conducting interviews and surveys with the prospective users of the system

Accepted Answer

The design phase of the SDLC focuses on developing a detailed plan for how the system will be implemented. This plan includes specific specifications for how the system will be executed, including hardware, software, and networking components. This document is typically referred to as the system design document, and it serves as a blueprint for developers to follow when building the actual system. Options A, B, and D are outcomes of earlier phases in the SDLC, such as the analysis and requirements gathering phases.

Question 17

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 have zero slack or float time, meaning any delay in these activities will delay the overall project completion time. Therefore, activities on the critical path are less flexible than non-critical activities.

Question 18

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

Accepted Answer

External users are individuals or entities outside of the company, such as customers, suppliers, investors, or government agencies, who have an interest in the company's financial information but are not part of its internal management or employees.
