4. Create a NOT List

I love this one. Nothing irks me more than a vendor soliciting feature requests without fixing critical longstanding bugs. While I wouldn't expect a NOT list to be written in stone, the mere existence of one might help to keep priorities straight. Sometimes that means saying no to crazy feature requests.

I completely agree. Usually the client will say YES! to each and every new feature idea that pops up during meetings. Forcing an explicit list of NOT-features might be a good excercise... I have to try this next time =)
