Website Upgrade Incoming - we're working on a new look (and speed!) standby while we finalise the project

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.

My preference is to not use progress override for two reasons

1. It is the "best possible" case and if you really do need to wait until the predecessor of the out of sequence activity has completed and this results in overunning a key milestone you will not be warned by the system until the next reporting cycle and at that stage it may be too late.

2. The Total Float calculations to the predecessor of the out of sequence are now meaningless and if this activity should still be on the critcial path (reason 1) then you have probably stopped watching it as closely as you should as it will now have float.

I believe it is safer to use retained logic and then if the out of sequence no longer relies on the predecessor you will find this from the out of sequence report (or by vitue of the system warning you that you will overrun a key milestone) and you can correct the logic to correctly reflect the situation.

The driving depends on the progress of the successor(s), not the activity itself.
eg. If the successor activity not commenced, start date determine either it linkage or data date; and
If the successor activity is commenced, the calculation will depend on the scheduling option - "retain logic" or "progress override"
