Question 1

The ________ is a sequence of activities that determine the earliest date by which a project can be completed.

Accepted Answer

The sequence of activities that determine the earliest date by which a project can be completed is called the critical path. The other options are not related to project management.

Question 2

A ________ shows the tasks, dates, and dependencies for the tasks of a project.

Accepted Answer

A Gantt chart displays the project schedule, including start and end dates, milestones, and dependencies between tasks. It helps project managers to plan, schedule, and track the progress of a project.

Question 3

Crispies is a breakfast cereal manufacturing company. It is shifting its manufacturing process from batch processing to assembly line production. The information system for the assembly line is ready to be installed. Crispies decides to completely shut down the batch processing system and install the new assembly line. This style of conversion is known as ________.

Accepted Answer

The style of conversion described in the scenario is a plunge installation, where the old system is shut down completely and the new system is installed. This is in contrast to parallel installation, where both systems are run simultaneously for a period of time, phased installation, where the new system is implemented in stages, and pilot installation, where the new system is tested in a small area or group before a full rollout. Preemptive installation is not a recognized term in the context of information systems conversion.

Question 4

A ________ involves balancing three critical factors: requirements, cost, and time.

Accepted Answer

A trade-off involves balancing the competing demands of requirements, cost, and time to find the best approach to complete a project successfully. A work breakdown structure (WBS) is a hierarchical decomposition of the project scope into manageable components. A test plan is a document detailing the approach, objectives, resources, and schedule of a software testing effort. A critical path refers to the longest sequence of dependent activities that determines the shortest possible duration of a project. A diagnostic plan is a systematic approach to identifying and resolving problems with a system or process.

Question 5

According to Brooks' Law, adding more people to a late project will ________.

Accepted Answer

Brooks' Law states that adding more people to a late project will actually slow the project down due to diseconomies of scale. This is because adding more people means there are more people to coordinate and communicate with, which can actually increase the amount of time required for coordination and communication. Additionally, new team members may require additional training and onboarding, which can also slow down the project progress.

Question 6

List and explain four critical factors for development project management.

Accepted Answer

The answer of List and explain four critical factors for...

Question 7

Discuss some of the key aspects to developing successful process and systems development projects.

Accepted Answer

The answer of Discuss some of the key aspects to...

Question 8

The critical path is the sequence of activities that determine the earliest date by which the project can be completed.

Accepted Answer

The statement accurately defines what the critical path is in a project management context.

Question 9

Rapid application development, the unified process, extreme programming, and scrum have led to ________.

Accepted Answer

These four methodologies are all considered part of the agile development approach, which emphasizes flexibility, collaboration, and rapid iteration in the software development process.

Question 10

Brooks' Law states that adding more people to a late project reduces the need for coordination.

Accepted Answer

Brooks' Law actually states that adding more people to a late project increases the need for coordination, which can further delay the project.

Question 11

The final work breakdown structure (WBS) plan shows planned tasks, dependencies, durations, and resource assignments. It is denoted as ________ WBS.

Accepted Answer

The term "baseline" is commonly used in project management to denote the final approved version of a plan or document. The WBS baseline plan includes all of the planned tasks, their dependencies, estimated durations, and assigned resources, and serves as a reference point for tracking progress and measuring performance throughout the project.

Question 12

In systems development, documents, designs, prototypes, data models, database designs, and working data entry screens are examples of ________.

Accepted Answer

Deliverables are the tangible outputs or outcomes of a project or process. In systems development, documents, designs, prototypes, data models, database designs, and working data entry screens are some examples of deliverables.

Question 13

Which of the following is True of paired programming?

Accepted Answer

Paired programming involves two programmers working together at the same computer, with one person typing while the other person reviews and discusses the code being written.

Question 14

What are the tools used when planning information systems (IS) projects?

Accepted Answer

The answer of What are the tools used when planning...

Question 15

Define cost feasibility and schedule feasibility.

Accepted Answer

The answer of Define cost feasibility and schedule feasibility....

Question 16

The situation that occurs when the addition of resources creates inefficiencies is known as ________.

Accepted Answer

Diseconomies of scale occur when increasing the scale of production leads to decreasing efficiency or increasing costs per unit. This is often due to communication difficulties, coordination problems, and a lack of specialized management. The other options (B, C, D, and E) are unrelated to this situation.

Question 17

Which of the following is one of the keys to successful systems development life cycle (SDLC) projects?

Accepted Answer

The work breakdown structure is a key tool in SDLC projects as it helps to break down complex projects into smaller, more manageable pieces, enabling better planning and control of the project. The other options listed are useful project management tools but are not specific to SDLC projects.

Question 18

The systems development life cycle (SDLC) process follows a linear sequence from requirements to design to implementation. Therefore, the systems development life cycle (SDLC) process is also known as the ________.

Accepted Answer

The SDLC process is often referred to as the "waterfall method" because it follows a sequential, linear flow from one phase to the next, just like a waterfall flows from top to bottom in a continuous, predictable manner.

Question 19

Define technical feasibility and organizational feasibility.

Accepted Answer

The answer of Define technical feasibility and organizational feasibility....

Question 20

The term ________ refers to a set of management policies, practices, and tools that developers use to maintain control over the systems development life cycle (SDLC) project's resources.

Accepted Answer

Configuration control refers to the policies, practices, and tools that enable developers to maintain control over the resources used during the SDLC project. It involves monitoring and managing changes to system components, such as hardware, software, documentation, and other related items to maintain their integrity and ensure that they are consistent with project goals and requirements. The purpose of configuration control is to prevent unauthorized changes that might compromise project quality, cost, or schedule.
