Decades ago, bosses made decisions and underlings obeyed. In today’s fast-changing, “flatter” Internet-based world, every project calls on a wide variety of people to participate, and simply giving orders no longer works. Negotiation, once the province of experts, is now a skill required in everyone’s lives. Where such talks were formerly a win-lose proposition, today they only work if both sides win. A “negotiation revolution” now teaches these principles worldwide.

As the world gets more connected, and long-separated populations begin to meet in a human “family reunion,” conflicts can boil over, and the need for resolution is greater than ever.
