* There are several advantages to group decision making. Group decisions provide more complete information than do individual ones. A group will bring a diversity of experience and perspectives to the decision process that an individual, acting alone, cannot. Groups also generate more alternatives, because of a greater quantity and diversity of information. Group decision making increases acceptance of a solution. If those who will be affected by a solution and who must implement it can participate in making it, they will be more likely to accept the solution. Since group decision-making is consistent with democratic ideals, decisions made by groups are perceived as being more legitimate than decisions made by a single person. There are several disadvantages to group decision making. Group decisions are time consuming, and groups almost always take more time to make a decision than an individual would take. There may also be minority group domination, because group members will differ in many ways: for example, status in the organization, experience, verbal skills, or assertiveness. A minority group that dominates the group decision-making process will have an undue influence on the final decision. Another problem focuses on the pressures to conform in groups. This pressure can result in groupthink—group members withhold deviant, minority, or unpopular views in order to give the appearance of agreement . Finally, there is ambiguous responsibility. Since group members share responsibility, who is actually responsible for the final outcome? * When confronted by a complex problem, most people will reduce the problem to its simplest level and satisfice by seeking solutions that are satisfactory and sufficient. Eschewing full rationality, they operate within bounded rationality and construct simplified models to extract the essential features of the problem and then behave rationally within the limits of the simple model. Here is how the bounded rationality typically o
