Summary: Discussing the issues that can be easily agreed on before addressing the difficult issues.
In complex negotiations, there are usually many deal points that need to be discussed and negotiated. Issues such as price, delivery schedules, service agreements, warranty, who will actually perform the work, training, and how add-ons or additional work will be handled are all examples of negotiable issues that need to be determined. If both parties are close to agreement on these issues, it may be best to discuss them first in the negotiation.
Example
When unions and management teams negotiate, they almost always negotiate the easiest points up front, and then save the economic issues for the very last. This serves two purposes. First, it speeds up the negotiation by getting resolution to the issues on which both parties agree. Second, it helps build the relationship between counterparts by allowing them to reach agreement on the easier issues.
