A Delphi study is a structured communication technique used to gather expert opinions and reach a consensus on a specific topic. It typically involves multiple rounds of questionnaires sent to a panel of experts, who provide their insights anonymously. After each round, a facilitator summarizes the responses and shares them with the group, allowing participants to reconsider their views based on the collective feedback. This method is often used in fields like healthcare, education, and technology to forecast trends, identify challenges, or develop guidelines. The iterative process helps refine ideas and ensures that diverse perspectives are considered, ultimately leading to more informed decision-making.
