What This Is

Group decision making is a collaborative process where a group of individuals work together to make a decision.

This approach can be beneficial in various settings, including business, education, and government.

    2. Increased free-riding
    3. Decreased accountability

Practical Application

A supervisor is leading a team of employees to decide on a new project. The team is composed of individuals with different backgrounds and expertise. The supervisor uses the Nominal Group Technique (NGT) to gather and prioritize ideas from the team. The team members are asked to generate ideas silently, and then share their ideas with the group. The supervisor facilitates the discussion and ensures that all ideas are considered. After prioritizing the ideas, the team decides on a new project that combines the best ideas from each member.

Common Mistakes
