Effective group decision making typically involves several key steps: 1. Problem Identification: Clearly define the problem or decision to be made. 2. Information Gathering: Collect relevant data and perspectives from all participants. 3. Brainstorming: Encourage open and diverse ideas without immediate judgment. 4. Evaluation of Alternatives: Assess the pros and cons of each option. 5. Decision Making: Use methods such as voting, consensus, or compromise to choose the best alternative. 6. Implementation: Develop a plan to execute the decision. 7. Follow-Up: Monitor the outcomes and make adjustments as necessary.
