Martin Fowler writes about a few XP projects he's aware of that have very low defects rates: one bug report per month, or even one bug report per year. Whenever I've mentioned such a thing to people in the past (there's been a few other projects reporting significant reductions of bug-rates when they started doing XP - the ones Fowler mentions are new to me), they can't believe if. Their immediate reaction to reply with a comment like: "yeah, because they have no users or no software", or suggest that the people reporting these bug-rates are lying.

As I've mentioned before, Weinberg's Laws of consulting: ""In spite of what your client may tell you, there is always a problem.... Never promise more than a ten percent improvement. (If it were possible to achieve more than a ten percent improvement, there must have been a problem, but there isn't a problem, so...)"
