Delphi method

The Delphi method, or Delphi technique ( DEL-fy; also known as Estimate–Talk–Estimate, or ETE), is a structured communication technique, or method, originally developed as a systematic, interactive forecasting method that relies on a panel of experts. Delphi has been widely used for business forecasting and has certain advantages over another structured forecasting approach, prediction markets. Delphi can also be used to help reach expert consensus and develop professional guidelines.
