What is Critical Path?

The Project Management Body of Knowledge (PMBOK) defines the critical path as "the sequence of schedule activities that determines the duration of the project."

Project managers can also apply the critical path methodology technique to "determine the amount of float on various logical network paths in the project schedule network to determine the minimum total project duration."

Critical Path – The longest complete path of a project.

Critical path method has to do with project planning. The critical path involves a sequence of steps where one step has to be completed before the next step begins. It is called the critical path because it represents the minimum amount of time within which a project can be completed.
