Hi all,
I have the following simple example to illustrate my problem: Say we have 3 activities A, B and C where durations are respectively 5, 10 and 10 days. Activity C are dependant of completion of both A and B. That means that activity A has a total and free slack of 5 days, which is correct. When I write "FS+1" from A to C it gives A a total and free slack of 4 days. Again correct. However, when I write anything with minus it suddenly reduce the free slack for A to zero, e.g. "FS-1" from A to C gives a total slack of 6 days for A, which is correct, but the free slack is now zero (0 days) whereas it should be 6 days?
I don’t understand this as in my mind activity A could still be delayed 6 days without delaying any other activity (C in this case).
Can anyone please explain?
Regards,
Bo
