The Delphi method is a process of gaining consensus from a group of experts while maintainingtheir anonymity. This form of forecasting is useful when no historical data are available from which todevelop statistical models and when managers inside the firm have no experience on which to base informed projections. A coordinator sends questions to each member of the group of outside experts, whomay not even know who else is participating. The coordinator prepares a statistical summary of the responses along with a summary of arguments for particular responses. The report is sent to the samegroup for another round, and the participants may choose to modify their previous responses. Theserounds continue until consensus is obtained.
