What is the Critical Path Method? | CPM | Total Float | Free Float | Network Diagram | PMP Exam

Critical Path Analysis is a systematic approach used to find the Critical Path in the Schedule Network Diagram.

Schedule Network Diagram
The graphical representation of relationship between activities is called as Schedule Network Diagram. Precedence Diagramming Method or Activity-on-Node is the most commonly used technique for drawing Network Diagram.

Critical Path
- Critical Path is the path with the longest duration.
- Duration of the Critical Path is the minimum time needed to complete a project.
- The activities on the Critical Path have the least Total Float relative to other paths

Total Float
It is the amount of time by which the Early Start of an activity can be delayed without delaying the overall project.

Free Float
It is the amount of time by which the Early Start of an activity can be delayed without delaying the Early Start of successor activities.
