Critical Path Analysis is a method for calculating each activities start/finish times and float, and the project’s critical path and longest duration. 1 minute video.
CPA/CPM Video Tutorial
Critical Path Analysis (CPA) or Critical Path Method (CPM) is a project network diagram method that employs forward and backward pass algorithms to calculate each activities earliest start and finish time, and based on each activities duration correspondingly the latest start and finish time. Consequently, path and activity float can be calculated and those activities with zero-float are identified as being critical. The chain of zero-float activities represents the critical path and the longest duration through the project..
