Hi Vazabee,
Welcome to this Microsoft Project newsgroup
The most common mistake is to not know how to update project effectively.
Relying on percentages is not necessarily the best way to update and many
people don't realise how important it is to enter Actuals followed by
estimates of Remaining work. I've covered most of this in my series on
Microsoft Project in the TechTrax ezine, particularly #27 & 28 (you might
like to look at the Questions section towards the end of 28 to help with
your other posting on a 3-hours delay), at this site:

(Perhaps you'd care to rate the article before leaving the site,

Thanks.)

Hope this helps - please let us know how you get on
