There are four major elements of critical path method:
- Critical Path Analysis: The critical path analysis deals with
the sequence of activities with the longest duration. Ant delay
with these activities will affect the delivery of the project.
- Float Determination: Here the float is the amount of time an
activity can sustain before it delays the project delivery.
- Early Start & Early Finish Calculation: This step is called
Forward Pass and is used to identify the earliest date an activity
can start and the earliest date it can get over
- Late Start & Late Finish Calculation: This step is called
Backward Pass and is used to determine the latest date an activity
can start and the latest date it can get over without causing any
delay.
