Negotiation involves parties resolving disputes, agreeing on actions, bargaining for advantages, or crafting mutual outcomes. Key aspects are two parties with shared objectives but differences, with outcomes including compromise, no agreement, or agreement to reconvene. An effective negotiation process involves planning, setting a positive tone, clarifying issues, negotiating, documenting agreements, and reviewing performance. Behaviors like establishing common ground and active listening aid negotiations, while preparation considers goals, alternatives, other party's positions, and creative solutions. Observers assess dependence, benefits, styles used, effective behaviors, and areas for improvement.
