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 ...
XOR - alternative (only one path possible) OR - alternative (one or more paths can be performed) AND - all paths have to be performed; The most common is AND, which means that every incoming activity has to happen before the outcoming one start. There are also two types of relations that concern activities outcoming from the node:
Nevertheless, Gantt charts are often preferred over network diagrams because Gantt charts are easily interpreted without training, whereas critical path diagrams require training to interpret. [9] Gantt chart software typically provides mechanisms to link task dependencies, although this data may or may not be visually represented. [ 4 ]
A play on the terms "software" and "hardware". Coined in 1966, the word indicates that sometimes the computer problem is not with the computer itself, but with the user. Lotus Software – Lotus founder Mitch Kapor got the name for his company from 'The Lotus Position' ('Padmasana' in Sanskrit).
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 ...

If resources are always available in unlimited quantities, then a project's critical chain is identical to its critical path method. Critical chain is an alternative to critical path analysis. Main features that distinguish critical chain from critical path are: Use of (often implicit) resource dependencies. Implicit means that they are not ...
