Upon reviewing a vendor's Integrated Master Schedule, created in MS Project, I noticed something very peculiar. Where some tasks could clearly be marked as Fixed Duration, everything was Fixed Units. I think there are two answers for this. Either there was a misunderstanding about the work to be performed or the person doing the schedule needs some help understanding task types. I believe working with MS Project can make your eyes bleed if you're not used to it. But if you're armed with just a little information about task types, it can be a whole lot easier. I would love to go into a detailed explanation about Fixed Work, Fixed Units, and Fixed Duration. If I did, however, you'd probably leave my site never to return. Instead, I found a very helpful video on YouTube. Why go hunting for this stuff when you can just find it here?
