Delphi Technique vs Focus Groups

Delphi Technique
The Delphi Technique begins with the development of a set of open-ended questions on a specific issue. These questions are then distributed to various ‘experts’.

Advantages of Delphi Technique.

• Allows a number of experts to be called upon to provide a broad range of views, on which to base analysis—“two heads are better than one”:
