Another problem -- or perhaps rather a restating of the first problem you 
mentioned -- is that even users with a very good _implicit_ knowledge of their 
work process often have a poor _explicit_ understanding of it. Often, a lot of 
important business requirements are overlooked because the users either plain 
doesn't realise that they're there, or because they take them as implicitly 
understood.

For the same reason, users are often terrible at prioritising between features 
and choosing between different solutions. Often, the highest priority goes to 
whichever feature the user thought of most recently.
