A negotiator should thoroughly prepare by learning about the opposing side's needs and priorities. During negotiations, one should vary the discussion between more and less important points, leaving critical issues for later. Strategic information should only be shared if useful information is expected in return. Offering to discuss the other side's important issues first builds good faith and provides insight. Linking small issues to larger priorities of the other side can help resolve minor matters without compromising major ones. Effective strategies include preparing well, developing a strategic plan, listening to understand the other side, and speaking minimally. Complex negotiations are best done in person rather than by phone.
