The document defines critical path analysis and explains how this technique should be used as an aid to decision making and not a substitute. The paper goes on to describe how CRITICAL PATH ANALYSIS is used at ACME as a central element of many projects, explaining how it is used and applied to solve many problems encountered during the course of a project. Finally, the article identified some of the limitations of this technique by citing examples in which CRITICAL PATH ANALYSIS fails to take into account certain variables likely to be encountered during a study.
