Never Split the Difference: Negotiating As If Your Life Depended On It

Voss was the FBI's lead international kidnapping negotiator, and the book is his account of the techniques he developed applied to ordinary negotiation — mirroring, labelling, calibrated questions, tactical empathy. The register is practical and sometimes melodramatic, which is both its appeal and its risk. For product direction the useful material is the specific conversational moves: most product leaders negotiate constantly (with stakeholders, engineers, designers, customers) and do so with techniques picked up informally. Voss gives a structured set of moves that work in most contexts. Pair with Cialdini for the persuasion side and with Young's Practical Empathy for the listening side.
