I'm kind of an old-timer here, been doing this quite a long time. I really wasn't familiar with the "Funnel" concept, as used in this way, although like a lot of the questioning techniques listed here I realize I have been doing it on a daily basis without knowing it. All the same, having seen it broken down and explained in this way will allow me to improve on the process dramatically I think. No matter how well you know your job - there's always room to learn more and improve!
