In negotiation, what does a 'win-win' outcome signify?

A 'win-win' outcome in negotiation signifies that both parties achieve satisfactory results. This concept is foundational in negotiation theory, as it emphasizes collaboration and mutual benefit rather than competition. The focus is on finding solutions that fulfill the interests of all involved, leading to a resolution that both parties can support.

In this type of outcome, both negotiators feel that their needs and concerns have been addressed to a reasonable extent, helping to foster positive ongoing relationships and facilitating future interactions. It enhances trust and cooperation, which are crucial in any successful negotiation process.

The other options highlight scenarios where either one party wins at the expense of the other, or where both parties end up dissatisfied. Such outcomes, by definition, do not align with the principles of a 'win-win' situation, which aims for mutual satisfaction and a positive consensus.
