The Delphi method can be described as a method for structuring a group communication process that allows a group of individuals as a whole to deal with a complex problem effectively. It is typically used in the areas of forecasting, broad or long range policy creation and in the development of management strategies.

The Delphi method is a technique for eliciting and refining the group judgements of recognised experts in situations where exact knowledge is not available but where partial information is available at the disposal of the individuals in the group.

Thus although the experts might not know the answer, they do have other relevant information that enables them to make estimates. The integration of individual interviews in a structured and moderated process helps to overcome the uncertainty inherent in complex problems and to approach the factual developments.
