Definition: The Group Decision Making is the collective activity wherein several persons interact simultaneously to find out the solution to a given statement of a problem. In other words, group decision making is a participatory process wherein multiple individuals work together to analyze the problem and find out the optimum solution out of the available set of alternatives.
In group decision-making, the number of participants often ranges from two to seven. It is not necessary that all the group members agree with each other and hence most of the times, the decision is taken on the basis of a majority if no other mode of a majority is prescribed. The majority means the number of votes in favor or against the proposed alternative.
There are several techniques that can be used to increase the efficiency of group decision making. These are as follows:
The concept of group decision making is based on the proverb that two heads are better than one. This means when the decisions are taken jointly, the expertise or experience of each member could be capitalized to reach to an optimum solution. Thus, the synergy gets created when the decisions are made in a group as more ideas and opinions pop up during the discussion session.
But however, the group decision making can be time-consuming and often leads to the conflict between the group members. Also, no single member is held accountable in case of a failure of such decision, since it is the whole group that agrees with that decision.
