What is the difference between total float and free float?

Question

Accepted Answer

Total float is the amount of time a schedule activity can be delayed without delaying the project completion date, while free float is the amount of time a schedule activity can be delayed without delaying the early start of any successor activity.

Total float is associated with the project completion date, while free float is associated with individual activities.
Total float considers all dependencies and constraints in the project schedule, while free float only considers the immediate successor activities.
Total float can be used to determine the flexibility of the overall project schedule, while free float helps in optimizing the schedule of individual activities.
For example, if a project has a total float of 10 days, it means the project can be delayed by up to 10 days without affecting the final completion date. On the other hand, if an activity has a free float of 3 days, it means that the activity can be delayed by 3 days without affecting the early start of its successor activity.
