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.
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 ...

Note (1) the critical path is in red, (2) the slack is the black lines connected to non-critical activities, (3) since Saturday and Sunday are not work days and are excluded from the schedule, some bars on the Gantt chart are longer if they cut through a weekend.
Path Analysis may refer to: Path analysis (statistics), a statistical method of testing cause/effect relationships; Path analysis (computing), a method for finding the trail that leads users to websites; Critical path method, an operations research technique; Main path analysis, a method for tracing the most significant citation chains in a ...
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.
Graphical Evaluation and Review Technique (GERT) is a network analysis technique used in project management that allows probabilistic treatment both network logic and estimation of activity duration. The technique was first described in 1966 by Dr. Alan B. Pritsker of Purdue University and WW Happ.
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 ...
