Explain how the Delphi group works. For what type of decisions is this method best suited? Why?

The Delphi procedure solicits input from a panel of experts who contribute individually. Their opinions are combined and, in effect, averaged. The first step in using the Delphi procedure is to obtain the cooperation of a panel of experts. At first, the experts are asked to anonymously predict a time frame for the expected breakthrough. The persons coordinating the Delphi group collect the responses, average them, and ask the experts for another prediction. In this round, the experts who provided unusual or extreme predictions may be asked to justify them. These explanations may then be relayed to the other experts. When the predictions stabilize, the average prediction is taken to represent the decision of the group of experts. The time, expense, and logistics of the Delphi technique rule out its use for routine, everyday decisions.
