Group Decision-Making: 3 Group Decision-Making Methods

Group decision-making is when a group of people reach a consensus and make an important decision together. Group decision-making, also known as collective decision-making or collaborative decision-making, is a process that depends on collaboration, group buy-in, and teamwork. Group members can brainstorm possible outcomes, rank solutions, or use the majority rule to make a group decision. This collective approach allows for multiple viewpoints and displaces the consequences of a decision across group members.

There are many methods for effective group decision-making. Some of those group decision-making processes include:

1. 1. Majority rule: If a majority of the group members agree to a course of action, the minority in the group must accept it. This method does not require unanimity.
2. 2. Delphi technique: The Delphi method requires the group to generate a list of possible solutions. The group leader or group facilitator then pares the list down and presents the smaller list to the group, who then make a choice based on the smaller list. It can be easier to reach a consensus when there are fewer options.
3. 3. Weighted scoring: Each member of the group ranks the possible solutions numerically. The group leader tallies the results, and the choice with the highest score becomes the group's decision.

There are advantages to group decision-making, including:

1. 1. Collective buy-in: A decision made by a group means no team member in the group is responsible for the outcome of the decision. Everyone is a stakeholder, and the consequences and risks spread out among the group. The decision made by a group means that the decision carries more weight and value and is less likely to lead to failure.
2. 2. Diversity of viewpoints: A group with diverse perspectives can help inform its members and expand their own views. This can lead to a discussion that considers all angles, leading to a better quality decision.
3. 3. Synergy: Group decision-making allows individual members to share information, and this group synergy can lead to brainstorming sessions, alternative solutions, and better knowledge of the situation. This information sharing can impact and improve the final decision, leading to more effective choices than individual decision-making.

There are a few downsides to group decision-making. Some of the disadvantages of team decisions include:

1. 1. Slower processes: A group decision is more time-consuming than an individual's. Group decision-making sessions usually require group meetings and more contribution of time by the individual team members.
2. 2. Groupthink: A lack of diverse viewpoints in a group can lead to groupthink, where the decision-making process is without criticism or counterpoints, leading to a toxic group dynamic. It can also lead to a final decision with the illusion of collective buy-in, but it favors one viewpoint and is incomplete in its knowledge.
3. 3. Diffuse responsibility: If a decision is not positively received, it will be easy for individual group members to blame each other and deny accountability. If everyone is responsible for the outcome, no single individual receives the blame. In group decision-making, it is crucial to reach a consensus that is defendable by each team member and one where everyone is accountable.
