The term "Delphi Study" refers to a research method that involves a panel of experts anonymously providing feedback on a specific topic. The spelling of this term can be explained using the International Phonetic Alphabet (IPA) transcription system. It is pronounced as /ˈdel.fɪ ˈstʌd.i/, with the stress on the first syllable "del" and a short "i" sound in the second syllable "fi". The "ph" in Delphi is pronounced as "f" and the "y" is pronounced as "i".
A Delphi study is a research method used to elicit expert opinions and achieve consensus on a particular topic or issue. It is a systematic and structured approach that aims to gather and analyze collective intelligence from a panel of diverse experts.
In a Delphi study, a group of experts, chosen for their knowledge and experience in the subject area, are asked to answer a series of questionnaires or surveys. These questionnaires are designed to collect expert opinions and feedback on the issue under investigation. The responses are then compiled and analyzed by the researcher, who provides a summary of the group's collective opinions in subsequent rounds of questioning. This process is repeated until a consensus is reached or a predetermined level of agreement is achieved.
The Delphi study allows for multiple iterations and iterations can continue until the desired level of consensus is achieved or until no new information is being generated. The anonymity of the process is crucial as it ensures that experts can freely express their opinions without influence from other panel members.
Delphi studies have a wide range of applications across various disciplines, including business, healthcare, education, and policy-making. They are particularly useful in situations where there is uncertainty or controversy surrounding a specific topic and where the perspectives of multiple experts are needed to provide a well-rounded and informed opinion. The Delphi study method provides valuable insights and can be used to make informed decisions or guide future research.
The word "Delphi Study" is derived from the ancient Greek city of Delphi, which was renowned as a center of prophecy and wisdom in the ancient world. The word "Delphi" itself is believed to have originated from the Greek verb "delphus", meaning "womb" or "cavity". This etymology reflects the belief that Delphi was considered the navel, or the center, of the world.
The term "Delphi Study" was coined by Norman Dalkey and Olaf Helmer in the 1950s when they developed a participatory research method aiming to gather input and insights from a panel of experts on a specific topic. This method was inspired by the ancient practice of seeking wisdom and advice from the Oracle of Delphi.
