Integrative negotiation is also called interest-based, merit-based, or principled negotiation. It is a set of techniques that attempts to improve the quality and likelihood of negotiated agreement by taking advantage of the fact that different parties often value various outcomes differently. While distributive negotiation assumes there is a fixed amount of value (a "fixed pie") to be divided between the parties, integrative negotiation attempts to create value in the course of the negotiation ("expand the pie") by either "compensating" loss of one item with gains from another ("trade-offs" or logrolling), or by constructing or reframing the issues of the conflict in such a way that both parties benefit ("win-win" negotiation).
