The Delphi method: Substance, context, a critique and an annotated bibliography

This paper is concerned with a methodology for efficiently obtaining consensus from a panel of evaluators on questions that are shrouded in uncertainty and cannot be measured or evaluated in the classical sense. The methodology and its historical development are described, it is placed in context vis-à-vis other methods of subjective scaling, and a critique is provided. An extensive and current annotated bibliography is presented.
