critical path method (cpm)
A technique used to predict project duration by analyzing which sequence of activities has the least amount of scheduling flexibility. Early dates are figured by a forward pass using a specific start date and late dates are figured by using a backward starting from a completion date.
1. A network analysis technique used to predict project duration by analyzing which sequence of activities (which path) has the least amount of scheduling flexibility (the least amount of float). Early dates are calculated by means of a forward pass using a specified start date. Late dates are calculated by means of a backward pass starting from a specified completion date (usually the forward pass's calculated project early finish date).2. A scheduling technique using precedence diagrams for graphic display of the work plan. The method used to determine the length of a project and to identify the activities that are critical to the completion of the project.
