	The CPM or Critical Path Method was developed by Morgan R. Walker of the Engineering Services Division at Du Pont, and James E. Kelley, who worked at Remington Rand. Walker and Kelly were interested in solving the problem of improving scheduling techniques used in the construction of industrial plants; it is based on a deterministic or exact duration of each task.

−	The associated PERT technique was developed in the Special Projects Office of the US Navy, when Admiral W. F. Raborn recognised that an integrated planning system and reliable control system were necessary in scheduling Polaris ballistic missiles. With his support, a research team was established in 1958 to develop PERT (Program Evaluation Research Task). At the time of the Navy's first internal report on the matter, PERT became the Program Evaluation and Review Technique. D. G. Malcolm, J. H. Roseboom, C. E. Clark and W. Fazar, all from the research team sponsored by the Navy were authors of the first document published on PERT. ~~This method~~ is ~~based on~~ the probability of activity durations.	+	The associated PERT technique was developed in the Special Projects Office of the US Navy, when Admiral W.

It is similar to critical path analysis, but the probability of completing by the contract completion date is determined and monitored by way of a quantified risk assessment based on optimistic, pessimistic and most likely activity durations.

		+	A delay to progress of any activity on the critical path will, without acceleration or re-sequencing, cause the overall project duration to be extended, and is therefore referred to as a ‘critical delay’.
