Negotiation skills teaches how to negotiate successfully in different contexts through understanding negotiation types, planning strategies, and influencing others. The key points are: - Negotiation involves two or more parties attempting to reach agreement and can be distributive (win-lose) or integrative (win-win). - Planning involves establishing objectives, identifying agreements and issues, and framing the negotiation as a joint problem to solve. - Influencing others relies on understanding their position, perspective, and problems to find solutions through concessions, trade-offs, and rapport.
