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.

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.

Question 10

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

Question 12

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

Question 13

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

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.

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.

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.

Question 17

PERT is actually an acronym for Program Evaluation Review Tool.

Question 18

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

Question 19

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

Question 21

As part of effective IT planning in systems development life cycle,a return on investment (ROI)calculation may be performed as part of the economic feasibility analysis.Often,many of the benefits from a new information system may be intangible benefits (e.g.system is easier to use or system enhances customer service,etc.)that are hard to quantify in an income statement.What are some intangible benefits of a state-of-the-art course registration system at your college or university?
