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.

Does anyone have a better way of creating a filter for a Critical Path without using the Longest Path? I have a job where the total job has negative float however some activities in the critical path string has positive float.

Thanks,
JJB

you can fix a number for the total float and the filter will display all activities having a TF less than this number...

Total float LT (x)

You seem to infer that all activities listed as being on the critical path must have the same float in order to be a valid critical path. This was never a part of the definition of “critical path.”

Many issues can cause the longest chain of activities to have different float; activity and resource calendars, interruptible activities, start versus finish float, and constraints come to mind immediately. For more on this, I suggest that you review a paper that I once presented titled, “Longest Path Value” on my website at http://ronwinterconsulting.com/published.htm. Good luck!
