Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

What is the difference between Start Float and Finish Float?
Start Float = Late Start - Early Start
Finish Float = Late Finish - Early Finish

Replies

Start Float shows the delay of sctivity start that does not delay project finish if everything will be done as expected.
Finish float shows the delay of activity finish that does not delay project finish if everything will be done as expected.

Actually it is more interesting to understand the delay of activity finish that will not delay project finish if current activity will be done slower than expected (we call it super float).

I think that start float is most useful because you decide when to start each activity. When start is known finish is defined.

So what is the use of the option in Scheduling dialog box that allows you to choose betwee start float, finish float, or the smallest between them?
Both are calculated using Forward and Backward passes but still may be different.

Ali,
One is calculated by Forward Pass and the other is calculated using Backward Pass.

Hi Ali

Both yields same result but the way of computing is different
