The Delphi method is a forecasting process framework based on the results of multiple rounds of questionnaires sent to a panel of experts. After each round of questionnaires, the experts are presented with an aggregated summary of the last round, allowing each expert to adjust their answers according to the group response.
This process combines the benefits of expert analysis with elements of the wisdom of crowds. Several rounds of questionnaires are sent out to the group of experts, and the anonymous responses are aggregated and shared with the group after each round.
The experts are allowed to adjust their answers in subsequent rounds, based on how they interpret the "group response" that has been provided to them. Since multiple rounds of questions are asked and the panel is told what the group thinks as a whole, the Delphi method seeks to reach the correct response through consensus. The name refers to the Oracle of Delphi, a priestess at a temple of Apollo in ancient Greece known for her prophecies. The Delphi method allows experts to work toward a mutual agreement by conducting a circulating series of questionnaires and releasing related feedback to further the discussion with each subsequent round.
The experts' responses shift as rounds are completed based on the information brought forth by other experts participating in the analysis. The Delphi method seeks to aggregate opinions from a diverse set of experts, and it can be done without having to bring everyone together for a physical meeting. Since the responses of the participants are anonymous, individual panelists don't have to worry about repercussions for their opinions.
Consensus can be reached over time as opinions are swayed, making the method very effective. However, while the Delphi method allows for commentary from a diverse group of participants, it does not result in the same sort of interactions as a live discussion. A live discussion can sometimes produce a better example of consensus, as ideas and perceptions are introduced, broken down, and reassessed. Response times with the Delphi method can be long, which slows the rate of discussion.
It is also possible that the information received back from the experts will provide no innate value. The Delphi method is a process of arriving at group consensus by providing experts with rounds of questionnaires, as well as the group response before each subsequent round.
As a didactic process, the Delphi method has been designed to offer the benefits of sharing and exchanging opinions, so that respondents can discover the opinions of others, without excessive influence of visual confrontations which are usually dominated by those who speak powerfully or have the most prestige. The technique allows participants to deal with a complex problem in a systematic way. During each round, the relevant information is shared and enriches the knowledge of the panel members.
They are then in a position to make recommendations based on more complete information. Usually, one or more of these characteristics require the use of the Delphi method:.
