The Variables of Project Management • Can somewhat vary the following factors. 1. The total cost of the project, • e.g., increase expenditures 2. The scope of the product, • e.g., subtract from a list of features 3. The quality of the product, • e.g., increase the mean time between failure 4. The date on which the job is completed. • e.g., reduce the schedule by 20% • e.g., postpone project's completion date one month Adapted from Software Engineering: An Object-Oriented Perspective by Eric J.
