Negotiating is not a game of chance, and negotiation success is not a random occurrence. The greatest issue lies in a lack of preparation. Therefore, the topic of negotiation profiling is treated in great detail by the authors. The individual steps are summarized in a comprehensive negotiation planner at the end of the book. Practical checklists highlight success-relevant prerequisites. This is where the book comes in, providing the buyer with the opportunity to critically examine and potentially change their self-image and understanding of their role. It describes proven tools that are second nature to the trained seller. On this basis, the buyer can selectively and proactively leverage the advantages of an interdisciplinary showcase with the aim of achieving even better negotiation results in the future.
