I am referring to video "L06.06.2_Develop_Schedule_HR.mp4" in which the critical path method is shown. This also links to figure 6-18 of the PMBok Guide, 5th edition.
I do not understand all the numbers inside the activity boxes. e.g., activity B has a float of 5 days. Do you have an example which explains all the numbers, forward and backward pass, float etc. in more detail using the presented schedule model format?
Ah, I think I have the answer: The float or free float is the difference of Late Start and Early Start date. So for activity B it is 11 - 6 = 5 days. Result: The project manager can wait 5 more days for activity B without delaying the successor activity D.
What is the difference between total and free float?
