A method for obtaining independent forecasts from an expert <a href="search.pl?p=panel">panel</a> over two or more <a href="search.pl?p=rounds">rounds</a>, with summaries of the anonymous forecasts (and perhaps reasons for them) provided after each round. Delphi has been widely used in business. By applying well-researched principles, Delphi provides more accurate forecasts than unstructured groups (Rowe and Wright 1999). The process can be adapted for use in face-to-face group meetings, and is then called mini-Delphi or <a href="search.pl?p=Estimate-Talk-Estimate">Estimate-Talk-Estimate</a> (ETE). Rowe and Wright (2001) provide principles for the use of the Delphi technique. <o:p></o:p></P>
