Analyzing Individual Decision Making Versus Group Decision Making for Alternative Selection

摘要

Many 'real world' decisions are made by groups. It is rare that the responsibility for a very important decision is given to a single decision maker with complete authority. Group decision making adds both advantages to the process as well as disadvantages. The time required to coordinate a deliberated decision within the group is the biggest difficulty in the group decision making process. In addition to this, the perceived influence of more senior participants and their ideas affect the originality of the group decision and the credibility of the contribution of 'all' the participants. The focus of this research is to explore the answer to the problem: 'Are decisions made by groups really that much different from the decisions made by individuals in the group.' A slightly different focus can also be employed: 'Do individuals really conduct themselves differently when they make decisions as members of a group or when they reach decisions by themselves.' In order to find the answer, the evaluation will be implemented by nonparametric statistical methods to test if there is any concordance among the group and individual decisions. The resulting values for the evaluation and a general conclusion for selecting the best primary training aircraft will be provided at the end.
