Expert opinions (Delphi)

The Delphi method is a technique for the systematic solicitation of expert opinion.

A carefully selected group of experts are asked about their insights about a particular future trend. Their responses are summarised and the results sent back to the respondents, who have the opportunity to re-evaluate their original answers based upon the responses of the group.

This process is then repeated in an iterative refinement of individual and group foresight, which will usually lead to the establishment of a consensus view.
