This document discusses strategies for effective negotiation. It outlines two main approaches: advantage seeking, which prioritizes individual gain in the short term but can damage relationships, and joint gain seeking, which takes more time but expands opportunities for mutual benefit over the long run. Key tactics for joint gain seeking include focusing on interests rather than positions, developing multiple options to link differences, using objective criteria, and separating people from the problem. Trust is important but must be built through authentic communication and keeping commitments. The document provides advice for negotiations involving groups, such as establishing process norms and facilitating discussions to ensure all voices are heard.
