This book is great not only for sales people to understand how to navigate sales organizations, but also for those who deal with the sales process to know how you can help, what your role can be, and when there are problems. Part philosophy and part guidebook, I would recommend this to all of my friends and family as we are all, in the end, in sales. Some sell products, some sell ideas, some sell themselves for a job. This book applies to all of them.
