I'm a lawyer and mediator. I represent businesses in disputes with their insurers and in other complex litigation. I also assist machinery companies and manufacturers (primarily international) with equipment sales, non-disclosure agreements, and business issues. I also mediate commercial disputes.
This is a great book on principled negotiation. As a lawyer and mediator, the concepts in this book were not new to me, but the book puts things together in a very organized and easily understood package. I will certainly be recommending it to some of my clients.
If there is one thing that detracts from the book, it is that many of the examples remain dated. I am afraid that, to a younger listener, the book might seem somewhat obsolete. Of course, that is not true at all -- the concepts and principles, which are actually rather new in the grand scheme of things -- remain very valid.
Perhaps this would not have jumped out to me except for the fact that the authors make the point at the beginning that this is a revised and updated edition of a classic. Revised, maybe. Updated? Not so much.
Still, the book contains many timeless and valuable lessons.
