A project planning technique that is used for developing strategy and schedules for an undertaking using a single-time estimate for each activity of which the project is comprised. In its basic form, i.e., concerned with determining the critical path, that is, the longest sequence of activities through the project network from beginning to end. CPM arose from a jointly sponsored venture of E.I. du Pont de Nemours and Company and the Sperry-Rand Corporation (Kelley 1961).
