Magnitude Discrimination Index: A Merger of Delphi Assumptions and Realities.
Baratta, Mary Kathryne
The advantages of the Delphi Technique are that it relies on collective expert judgment, prevents the excessive influence in decision-making of those in positions of status, and encourages consensus. The technique consists of five steps: (1) asking experts to list items relevant to a topic; (2) returning the list to the participants and asking them to evaluate it according to given criteria; (3) returning the list, with a summary of responses, to the participants and asking those with minority responses to revise or defend their position; (4) returning the list and an updated summary of majority and minority responses again to provide additional opportunity for revision; and (5) formalizing a report of results arrived at by the repeated questionings. Traditionally, three major conventions are used in the final reporting: reporting by importance, reporting by consensus, and reporting by both consensus and importance. An additional alternative, which combines the elements of consensus and importance in one measurement, is a magnitude discrimination index. The advantages of this method of reporting are explored in relation to the other three methods. A bibliography is included. (MB)
