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.

Mandatory Finish Constraint

Dears,

I know I should avoid mandatory constraints, but the client forces the team to use a mandatory finish milestone (Project Finish Date) that leads to negative lag. Our mandatory finish constraint on “Project Finish Date” caused a network logic violation, where the successor completes before the predecessor.

I want to know if there is any way that all preceding activities fall into line before the “Project Finish Date”?

Thanks

The negative float is the problem your management has to solve.  The early dates are what you are planning to do based on the current schedule. The late dates are what you are required to do to achieve the contract completion. The difference (negative float) is the challenge.

Accellerating the schedule in the computer is quite easy - doing it in the field is a lot harder.  For more on schedule compression see the WP Schedule Compression at: https://mosaicprojects.com.au/PMKI-SCH-014.php#Process6

Indeed there is, Hamid. The late dates show what you are looking for. Yes, you should not use mandatory dates.
