Group discussion is a form of communication where participants discuss ideas on a common topic to arrive at a solution or decision. It is used by organizations for decision making, problem solving, and evaluating job candidates. The objective is to generate ideas, understand perspectives, and make decisions through information exchange. Discussion topics can be factual, controversial, or abstract. Participants are expected to have skills like teamwork, reasoning, leadership, and creativity. Effective group discussion involves all participants sharing ideas, asking questions, listening, and summarizing to keep the conversation on track and arrive at a conclusion.
