(Q-4) Analyze the five major variables of project management for information systems.

Scope defines what work is or is not included in a project. Project management defines all the work required to complete a project successfully, and should ensure that the scope of a project does not expand beyond what was originally intended.

Time is the amount of time required to complete the project. Project management typically establishes the amount of time required to complete major components of a project. Each of these components is further broken down into activities and tasks.

Cost is based on the time to complete a project multiplied by the cost of human resources required to complete the project. Information systems project costs also include the cost of hardware, software, and work space.

Quality is an indicator of how well the end result of a project satisfies the objectives specified by management. The quality of information systems projects usually boils down to improved organizational performance and decision making.

Risk refers to potential problems that would threaten the success of a project. These potential problems might prevent a project from achieving its objectives

by increasing time and cost, lowering the quality of project outputs, or preventing

the project from being completed altogether.
