Delphi technique

Multistep method used to estimate future demand for a product or service whereby a special group of experts in economic forecasting exchange views and then each individually submits estimates and assumptions to an analyst who reviews all the data received and issues a summary report. The summary report is then discussed and reviewed individually by the group members who each submit revised forecasts to the analyst, who then reviews the material again and issues a secondary report. This process continues until all participants reach a common ground.

Method of providing members of a group with the ideas of others without a face-to-face meeting. An individual member writes down his thoughts on a problem and submits them to a coordinator. The coordinator then compiles all comments received from the members and sends them to every member for review. Each member then provides feedback on the other members' comments and submits recommendations to the coordinator. Finally, the coordinator attempts to reach a consensus of opinion based on all comments received.
