A negotiation accord is often the result of an intense, laborious, and
evolutionary negotiation process. During this process, disputing part
ies are confronted with goal, judgment, and outcome conflict. This art
icle demonstrates the utility of a conflict resolution framework-Evolu
tionary Systems Design (ESD)-by using a Negotiation Support System. ES
D seeks to guide negotiators to move their individual goals and judgme
nts in such a way as to enhance the chance of achieving a common solut
ion. As illustrated by the use of NEGOTIATOR, a multiattribute utility
negotiation support system, we argue that computer mediation can prov
e to be an effective means to implement the ESD framework.
