Why should an IS auditor use the project management triangle while reviewing a project, where quality is a major concern?

A. increase in quality can be achieved, even if resource allocation is decreased.

The three primary dimensions of a project are determined by the deliverables, the allocated resources and the delivery time. The area of the project management triangle, comprised of these three dimensions, is fixed. Depending on the degree of freedom, changes in one dimension might be compensated by changing either one or both remaining dimensions. Thus, if resource allocation is decreased an increase in quality can be achieved, if a delay in the delivery time of the project will be accepted. The area of the triangle always remains constant.
