A = B + C
Example
Assume you’re planning a multi-stop road vacation. Each stop in your project represents a task, and the time it takes to travel from one stop to the next symbolizes the time required for each work.
Assume your road trip itinerary is as follows:
– Stop 1: Drive 4 hours to a town; Stop 2: Drive 3 hours to see the town; Stop 3: Drive 5 hours to a gorgeous area; and Stop 4: Drive 2 hours home.
You have 14 hours total available time for the entire journey before you have to return home.
Assume that, owing to unanticipated road restrictions, Stop 3 takes longer than expected, taking 6 hours rather than the intended 5 hours.
Because you have 14 hours overall for the journey and Stop 3 took 6 hours instead of the intended 5, this means:
– You have utilized 14 – 6 = 8 hours for the other stops and to finish the journey.
– The Critical Path Float for Stop 3 is the difference between the actual time (6 hours) and the total allowed time (14 hours), which equals 14 – 6 = 8 hours.
As a result, the Critical Path Float for Stop 3 in our road trip example would be 8 hours, indicating that even if Stop 3 took longer than expected, the project (or trip) can still be finished on time since there is still 8 hours of buffer time remaining within the total allowed time.
