What is Delphi method?
The Delphi method is a highly flexible problem solving process and a powerful research technique. It is used when there is an insufficient evidence base to make a decision and/or when expert experience and opinion are considered valuable. It has been used widely in numerous industry sectors including Health Care, Education, Business Management, Information Technology, Military Science, Engineering, and Transportation. Delphi technique comprises a series of questionnaires sent to a pre-selected group of experts. These questioners are usually items that can be ranked or scaled. They are designed to develop individual responses to the problems posed, and to enable the participants to revise, refine and evaluate their previous response in light of comments made by their peers.
