What is Delphi? How has the Delphi method stood up over time? How can the best of Delphi be adapted to new circumstances and problems?
The Delphi method is a group-based process for eliciting and aggregating opinion on a topic with a goal of exploring the existence of consensus among a diverse group of handpicked experts. The Delphi method was developed at the RAND Corporation in the early 1950s to obtain a reliable expert consensus, which is often used as a substitute for empirical evidence when it does not exist.
The four key characteristics of the Delphi method are:
- iterative data collection,
- participant feedback, and
- statistical determination of group response.
As a result, Delphi has become best practice for quantifying the results of group elicitation processes.
