The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. [1] A critical path is determined by identifying the longest stretch of dependent activities and measuring the time [2] required to complete them from start to finish.
X-Pert is geared to producing critical path method and PERT schedules for major, long-term projects (in one case [1] a duration now approaching 40 years).. Developed by users and contributors to the ICL 1900 PERT mainframe package, X-Pert is one of the few packages still fully supporting the activity on arrow project network process.
Activities that are on the critical path have a slack of zero (0). The duration of path adf is 14.83 work days. The duration of path aceg is 19.51 work days. The duration of path beg is 15.67 work days. The critical path is aceg and the critical time is 19.51 work days. It is important to note that there can be more than one critical path (in a ...
Critical path drag is a project management metric [1] developed by Stephen Devaux as part of the Total Project Control (TPC) approach to schedule analysis and compression [2] in the critical path method of scheduling. Critical path drag is the amount of time that an activity or constraint on the critical path is adding to the project duration ...
The Graphical Path Method (GPM) is a mathematically based algorithm used in project management for planning, scheduling and resource control. GPM represents logical relationships of dated objects – such as activities , milestones , and benchmarks – in a time-scaled network diagram.
The critical path is defined as the path between an input and an output with the maximum delay. Once the circuit timing has been computed by one of the techniques listed below, the critical path can easily be found by using a traceback method. The arrival time of a signal is the time elapsed for a signal to arrive at a certain point.

The actual critical path is ultimately the determining factor of every project's duration. Because earned value schedule metrics take no account of critical path data, big budget activities that are not on the critical path have the potential to dwarf the impact of performing small budget critical path activities.
