The Delphi Technique an Overview by Dr. Phil Davidson RESEARCH METHODOLOGY SIG April 12, 2018 Welcome to the Delphi Technique Agenda: Characteristics of the Delphi Technique Origins of the Delphi Technique Theoretical Framework
The Methodology Obstacles Faced by Students and Faculty Application Examples of the Delphi process Different types of Delphi designs Q&A Characteristics of the Delphi Technique Delphi is the name of a set of procedures for eliciting and
refining [a consensus of] opinions of a group of people. In practice, the procedures would be used with a group of experts or especially knowledgeable individuals (Dalkey, 1967, p. 1). Turoff and Linstone (1975) added to the definition of Delphi, describing it as A method for structuring a group communication process so that the process is effective in allowing a group of individuals, as a whole, to deal with a complex problem (Linstone, & Turoff, 1975, p. 3). Qualifier: The Delphi Technique seeks consensus of a group of experts, but the actual research focuses on anonymity of the participants to one another to avoid issues of pressure or groupthink. Origins of the Delphi Technique Delphi referring to the important oracle in ancient Greece, located in Delphi.
Delphic Oracle was the voice of the Apollo. Forecasts of future events. 1950s:RAND Corporation under direction of the U.S. Air Force, develop the Delphi Technique. Purpose? To FORECAST how many atomic bombs Russia would have to deliver to completely destabilize the U.S. infrastructure. Qualifier: "The key purpose for using the Delphi method remains the collection of informed judgment on issues that are largely unexplored, difficult to define, highly context and expertise specific, [and] future-oriented" (Fletcher & Marchildon, 2014, p. 3). Theoretical Framework
Prediction theory is the theoretical framework supporting research using the Delphi Technique. Kaplan, Skogstad, and Girshick (1950), relied heavily on the work of McGregor (1938), and Cantril (1938), but focused primarily on the process of improvement of prediction. Kaplan et al. focused on precision of prediction and how that might be improved. The theoretical foundation of the accuracy of prediction (prediction theory) appears to depend on a wide set of variables, including the individual and that individuals knowledge background, preferences, and biases [back to the issues of experts and expertise]. McGregor (1938). McGregor examined the concept of predictions as a form of psychological inference.
Cantril (1938) elaborated on McGregors work, dealing with the issue of validity and the certainty of predictions. The Methodology A tool to use for forecasting possible future solutions for problems that are unclear or data is missing. Usually considered a qualitative tool. Obstacles Faced by Students and Faculty 1. Future focused Delphi is not appropriate if the problem is clear and the student wants to determine best methods. 2. Expertise of panel members One of the biggest challenges is finding experts. I may spend more time vetting my expert panel than actually doing the research. Students frequently want to used experienced rather
than expert participants. The Nominal Group Technique may be a better choice in those situations. 3. Interaction of student research to expert panel The student researcher needs to be an active participant with the panel, adding new information, and collating information between rounds. 4. Validation of questionnaires Delphi commonly uses questionnaires. How will student validate those? Application of the Delphi Technique Romann et al. (2017). Big Data Analytics and SCM to 2035
