The process generally involves several key steps: 1. Selection of Experts: A panel of experts is chosen based on their knowledge and expertise in the relevant field. 2. First Round of Questionnaires: Experts are asked to respond to a set of open-ended questions. 3. Aggregation of Responses: Responses are collected and summarized by a facilitator. 4. Subsequent Rounds: Experts receive a summary of the previous round and are asked to revise their answers, considering the feedback from their peers. 5. Final Round and Analysis: This iterative process continues until a consensus or a stable range of opinions is reached.
