The book explains the functional perspective of group decision making is more of an effective approach to solving problems as long as you stick to the four major criteria ; The first is analysis f the problem. This is allowing the group to all be on the same page and know exactly what the problem is. Next is goal setting which is simply agreeing on what the group wants to reach as a whole. Next, is identifying the potential alternatives to reach the understood goal. Finally, the last criteria would be evaluating the alternatives. Not only should the group find a solution but they should also measure out which solution is the best one.

Jams Camron’s movie Avatar is a perfect example for the functional perspective of group decision making. In the beginning, the main character tried to fit in with a foreign tribe solely by himself, and no help from the scientists he worked with everyday. However, as soon as a real problem arose in which he had to save the entire tribe from militant forces, the group comes together to consider plenty of options on how they could make is work. Finally, the main character comes up with the idea they stick with because it is the most likely to succeed. This resembles the example from the book because all aspects of the group displayed their ideas and went with the best one.
