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.
The effectiveness of a decision is dependent on the groups efforts to analyze and understand the specific task and objective at hand, and identify the positive and negatives of all alternative choices to find the best solution possible.
[4] Vigilant Interaction Theory describes the group decision-making process as a series of interrelated sub-decisions leading to the final decision.
Therefore homogeneous groups consisting of members that activate independent will take longer to reach a decision.
Finally the VIT’s “functional requisites” can predict the quality of decisions in mono- and multicultural groups.
