The essence of the Delphi method is the feed-back of the results after the first phase of the research. The feed-back is the input for the second phase (and possibly a third phase) by which one tries to reach a consensus regarding a certain matter. The Delphi method is often used when conducting in-depth interviews with experts from several professions regarding a certain matter. Traditionally the method is used for ‘future research’. A large computer firm used this method to form a strategy for the development of new products. More recent applications are not merely focused on the future. The Delphi method is, for instance, also used by insurance companies for damage assessments.
