A mini‐Delphi approach: An improvement on single round techniques

Delphi studies have been used in many situations to gather and assess the group opinion of numbers of experts about the possible outcome of particular defined events. Such studies, however, are very costly in time and money. This paper poses the hypothesis that reduced scale Delphi studies provide more carefully considered viewpoints than the use of single round surveys. The hypothesis is examined through the use of three very different case studies and sufficient evidence is provided to prove that in these studies the hypothesis is valid.
