The field of Group Decision and Negotiation focuses on decision processes with at least two participants and a common goal. Such processes are complex and self-organizing and constitute multi-participant, multi-criteria, ill-structured, dynamic, creative, and often evolutionary problems. Major approaches include (1) information systems, in particular, negotiation support systems (NSSs) and group decision support systems (GDSs), (2) cognitive and behavioural sciences as applied to group decision and negotiation, (3) conflict analysis and resolution, (4) applied game theory, experiment and social choice, (5) artificial intelligence, and (6) management science as it relates to group decision making and negotiation. Many research initiatives combine two or more of these approaches.

Group decisions and negotiations can be performed in an intra-organisational as well as an inter-organisational context. Both consist of complex processes, including preference elicitation, proposals and counter-proposals, preference adjustment, and choice. Communication and decision making are the two key process steps in Group Decision and Negotiation and thus require sophisticated support in many ways.

Application areas of Group Decision and Negotiation include intra-organisational and inter-organisational coordination (as in operations management and integrated design, production, finance, marketing and distribution functions, such as coordination of all phases of the life cycle of a product), computer-supported collaborative work and meetings, electronic negotiations including negotiating agents and negotiation support systems, labour-management negotiations, inter-organisational, intercultural negotiations, environmental negotiations, and many others. See the Group Decision and Negotiation journal for further illustrations of the scope of the GDN field.
