Problem solving is the critical skill required.
The documented experience and well-articulated wisdom of the authors are that the best results are achievable without confrontation, humiliation, hostility and other negative elements often present in negotiations. A useful tool for both lawyers and nonlawyers involved in the transactional negotiation process, The Power of Nice is a remarkable negotiation road map. It comes with checklists and other learning aids for reaching interest-based goals and establishing and continuing important relationships. You can have more, but the other side has what they need, and considers the negotiation successful. This book demonstrates the important need for lawyers in training as well as those in practice, to understand their role as problem solvers.
