Group discussions allow multiple individuals to share ideas and perspectives to collectively solve problems or reach decisions. Key elements of effective group discussions include having a clear objective, encouraging active listening and open communication, establishing structure and roles, and managing time. Facilitators should prepare an agenda, stimulate participation from all members, and address any conflicts respectfully. Best practices involve setting ground rules, embracing diverse views, encouraging constructive feedback, documenting outcomes, and evaluating effectiveness. When implemented properly, group discussions can enhance problem-solving, creativity, and relationships.
