Question 1

The systems development life cycle has five phases: Planning,Analysis,Design,Implementation and Maintenance.

Accepted Answer

The systems development life cycle does indeed have five phases: Planning, Analysis, Design, Implementation, and Maintenance.

Question 2

The project sponsor is generally the same person as the project manager.

Accepted Answer

The project sponsor and project manager are two distinct roles in a project. The project sponsor is responsible for providing the necessary resources and support to the project, while the project manager is responsible for planning, executing, and monitoring the project activities. Although the project sponsor and project manager may work closely together, they are separate roles that require different skill sets and responsibilities.

Question 3

The 100% Rule is a rule requiring 100% planning of all external tasks.

Accepted Answer

The 100% Rule in project management requires that all work necessary to complete a project is included in the Work Breakdown Structure (WBS), not just external tasks.

Question 4

The breakdown of all of the project tasks needed for completion is often called the work breakdown structure.

Accepted Answer

A work breakdown structure (WBS) is a hierarchical decomposition of the project scope into manageable sections of work. It breaks down all the tasks required to complete the project into smaller, more manageable components, making it easier to plan and execute the project.

Question 5

Tasks that must be completed in a specific sequence but don't require additional resources or a specific completion time are considered to have task dependency.

Accepted Answer

Task dependency is when the completion of one task is necessary before another task can begin without requiring any additional resources or a specific completion time. These tasks must be completed in a specific sequence for the project to be successful.

Question 6

The design phase of the SDLC begins with a business need for a new or better information system.

Accepted Answer

The design phase of the SDLC begins after the analysis phase, which identifies the business need and requirements for a new or improved information system.

Question 7

The triple constraints of project management are also referred to as Dempster's triangle.

Accepted Answer

The triple constraints of project management are often represented as a triangle with scope, time, and cost as the three sides. This triangle is commonly referred to as the Project Management Triangle, but it has also been named Dempster's triangle after the management consultant George Dempster.

Question 8

The Technology Acceptance Model defines perceived usefulness as the extent to which a person believes that the use of a particular system would be free of effort.

Accepted Answer

The Technology Acceptance Model defines perceived usefulness as the extent to which a person believes that the use of a particular system would enhance their performance and job productivity. Perceived ease of use refers to the extent to which a person believes that using the system would be free of effort.

Question 9

The 15-15 Rule states that if a project is more than 15 percent over budget or 15 percent off the desired schedule,it will likely never recoup the time or cost necessary to be considered successful.

Accepted Answer

The statement accurately explains the 15-15 Rule.

Question 10

The triple constraints of project management include time,scope,and effort.

Accepted Answer

The triple constraints of project management include time, scope, and cost (not effort).

Question 11

Control Objectives for Information and related Technology (CobIT)provides managers,auditors,and IT users with a set of generally accepted measurements,processes,indicators,and best practices to assist them in maximizing the benefits derived through the use of information technology.

Accepted Answer

CobIT is a framework that provides guidance and best practices to maximize the benefits of information technology.

Question 12

Parallel or concurrent tasks are tasks that be done at the same time.

Accepted Answer

Parallel or concurrent tasks can be done at the same time, hence the statement is true.

Question 13

The analysis phase of the SDLC involves a complete,detailed analysis of the systems needs of the end user.

Accepted Answer

The analysis phase of the SDLC does indeed involve a complete and detailed analysis of the system needs of the end user. It is during this phase that the project team will gather requirements, identify potential solutions, and assess the feasibility of different options. This information will be used to guide the rest of the SDLC process, which includes activities such as design, development, testing, and implementation. Ultimately, the goal of the analysis phase is to gain a comprehensive understanding of the user's needs in order to create an effective and efficient system that meets their needs.

Question 14

The maintenance phase of the SDLC is the final phase of the SDLC and includes making changes,corrections,additions,and upgrades (generally smaller in scope)to ensure the system continues to meet the business requirements that have been set out for it.

Accepted Answer

The maintenance phase of SDLC indeed involves making changes, corrections, and upgrades to ensure the system continues to meet the business requirements.

Question 15

Control Objectives for Information and related Technology's (CobIT)guidance is guided by a structure that corresponds to the SDLC,namely: Plan and Organize,Acquire and Implement,Deliver and Support and Monitor and Evaluate.

Accepted Answer

The statement correctly describes how the Control Objectives for Information and related Technology (CobIT) guidance is structured according to the four stages of the SDLC (Plan and Organize, Acquire and Implement, Deliver and Support, and Monitor and Evaluate).

Question 16

Segregation of duties can be the source of IT material weaknesses when assessing the effectiveness of internal controls over the company's accounting information system.

Accepted Answer

Segregation of duties is a fundamental aspect of internal controls, particularly in accounting information systems. The absence of proper segregation of duties can increase the risk of errors, fraud, and misuse of confidential information, which can compromise the integrity of financial reporting. Therefore, a lack of segregation of duties can be considered as a material weakness in the company's IT internal controls.

Question 17

PERT is actually an acronym for Program Evaluation Review Tool.

Accepted Answer

PERT stands for Program Evaluation and Review Technique, not Program Evaluation Review Tool.

Question 18

The project sponsor generally obtains necessary resources for successful project completion.

Accepted Answer

The project sponsor is responsible for obtaining the necessary resources for the successful completion of the project. This could include funding, equipment, personnel, and other resources required for the project team to achieve the project objectives. However, the project manager plays a key role in identifying the required resources and communicating those needs to the project sponsor.

Question 19

The Project Manager is the lead member of the project team that is responsible for the project.

Accepted Answer

The Project Manager is the person accountable for achieving the project objectives. They lead the project team and are responsible for planning, executing, monitoring, controlling, and closing the project.

Question 20

The Technology Acceptance Model defines perceived ease of use as users adopting a new or modified system to the extent they believe the system will help them perform their job better.

Accepted Answer

The Technology Acceptance Model defines perceived ease of use as the degree to which a person believes that using a particular system would be free of effort, not about job performance improvement.
