Not a complaint, Houston. It's an observation that there are more references to selling concepts here than there is sharing of practical experiences. I have yet to see one member here share their actual experience with SPIN selling even though it has been mentioned countless times.
I don't use the system. So I can't share my results with it. What is the use of talking about something if nobody seems to be engaged in it? You read SPIN Spelling a while ago, according to your post on that thread. I don't see you sharing your results and observations from it. And I don't see you answering Borisoff's two questions.
My comments are no reflection on Rackham's work. I did read his book and I view at as a viable system. I choose not to use it.
If you don't believe that the sharing of real life experiences in selling is more valuable to a forum like SalesPractice then tossing out the names of books and concepts, then you wouldn't understand. I trust that's not the case.
