Delphi is a high level language supporting object-oriented design. It is a rapid application development used to develop applications ranging from database solutions to mobile applications and is used on Windows as well as Linux.
A systematic forecasting method that involves structured interaction among a group of experts on a subject. The Delphi Technique typically includes at least two rounds of experts answering questions and giving justification for their answers, providing the opportunity between rounds for changes and revisions. The multiple rounds, which are stopped after a pre-defined criterion is reached, enable the group of experts to arrive at a consensus forecast on the subject being discussed.
Using the Delphi Method
First, the group facilitator selects a group of experts based on the topic being examined. Once all participants are confirmed, each member of the group is sent a questionnaire with the instructions to comment on each topic based on their personal opinion, experience or previous research. The questionnaires are returned to the facilitator who groups the comments and prepares copies of the information. A copy of the compiled comments is sent to each participant, along with the opportunity to comment further.
At the end of each comment session, all questionnaires are returned to the facilitator who decides if another round is necessary or if the results are ready for publishing. The questionnaire rounds can be repeated as many times as necessary to achieve a general sense of consensus.
Benefits of the Delphi Method
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.
Disadvantages of the Delphi Method
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. Response times 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.
