The Delphi process is a research method used to gather opinions and reach consensus on a particular topic or issue from a group of experts. It typically involves multiple rounds of questionnaires or surveys, where experts provide feedback anonymously and can revise their answers based on the input of others. The process continues until a consensus is reached or until the predetermined criteria for ending the process are met. The Delphi process is commonly used in fields such as healthcare, education, and business to forecast trends, make decisions, or identify priorities.
