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.
