The critical path method (CPM) is a project management technique that’s used by project managers to create an accurate project schedule. In the given example below the total float for activity 3 is 5 and the free float is also 5(ES of activity 5-EF of activity 3). Total Float is the maximum amount of time an activity can be delayed without delaying the project whereas Free Float is the amount of time an activity can be delayed without impacting the Early Start date of any of its immediate successors. It doesn’t replace other frameworks but rather works alongside them. Total float is 0 on the critical path. ).
