The Delphi method is a structured communication technique used to gather expert opinions and achieve consensus on a specific topic. It involves a series of questionnaires sent to a panel of experts, who provide their insights anonymously. After each round, a facilitator summarizes the responses, allowing participants to reconsider their views based on the feedback from others. This iterative process continues until a consensus is reached or the responses stabilize. The Delphi method is commonly used in fields like forecasting, policy-making, and technology assessment, making it a valuable tool for decision-making in uncertain situations.
