Many of the other books on the subject describe strategies how to open or how to close opportunities. In my world a customer kicks me out of the door if I would try to close him in the 1st or 2nd call.
Mr Rackham described in a very understandable language what it takes to run a sales team involved in selling systems with a high ASP and a >6 month sales cycle. After reading the book I understood why some things worked and others didn't. As a result I was able to put a strategy together on how to increase the sales and how/who to hire to extend my team.
I feel like I was given the keys to the secret kingdom of strategic sales.
Although still in implementation I feel great to have now at least an idea how to run my business where previously I was working from quarter-end to quarter-end trying to make the number.
One improvement would be for the authors to use a little more humor. I am a firm believer that a little fun helps to keep you going from page to page....
