Effective group decision-making

The Effective Group Decision-Making Theory is one of several theories of intercultural communication.

Developed in the 1990s by John G. Oetzel it focuses on decision-making within groups integrating also the Vigilant Interaction Theory (Hirokawa and Rost) as well as the Face Negotiation Theory by Ting-Toomey. It takes the influence of culture on group processes as a basis and it depends on social interactions among group members.The purpose of this study which is to determine whether relationship between group interaction quality and group decision performance can be generalized to established organizational groups. Thus the theory presents different group constellations and their way of making decisions. Emphasizing the possible success Oetzels theory belongs to the theories focusing on effective outcomes. Oetzel states that groups making decisions can be homogeneous, i.e. monocultural or heterogeneous, i.e. multicultural. Within multicultural groups, there exist different decision-making strategies with the individuals due to the diverse cultural backgrounds. These different strategies may lead to conflicts in the process. The diverse backgrounds of the individuals will also result in different strategies for dealing with those conflicts. The effectiveness of a decision is dependent on its quality and appropriateness.

Vigilant Interaction Theory describes the group decision-making process as a series of interrelated sub-decisions leading to the final decision. According to the theory the quality of the final decision is based on 1)analysis of the problem/ situation 2) establishment of goals and objectives 3)evaluation of positive and negative qualities of the available choices. This theory shows that group decision performance is largely depended on the wise group decision-makings from social interactions.

The theory contains 14 propositions as a core. Of those, the first half focuses on the influence of input on the process of decision-making. Here Oetzel assumes that individual members of homogeneous groups activate either independent self-construals (such members emphasize the quality decision and are not primarily interested in relationships among members) or interdependent self construals (those members are concerned for cooperation and others; the decision is secondary). Therefore homogeneous groups consisting of members that activate independent will take longer to reach a decision. The process is less cooperative and will have more conflicts than with homogeneous groups whose members activate interdependent self-construals. In addition to that, heterogeneous groups will less likely reach consensus than homogeneous groups since with homogeneous groups the single members are more committed to their group and that their contributions are treated more equally than in heterogeneous groups. Furthermore Oetzel claims that groups were the majority of members activate independent self-construals will most likely use dominating conflict-strategies, whereas with groups were most members use interdependent self-construals will use strategies of avoiding, compromising or obliging when dealing with conflicts.
