  1. Delphi AED 615 Q. Molina

  2. Objectives • Become familiar with the social science research method known as Delphi.

  3. Prerequisite Tools • There are no Prerequisite tools required for the Delphi Research Method

  4. Delphi is a group process for eliciting, collating, and generally directing informed (expert) judgment towards a consensus on a particular topic. Purpose

  5. Uses • Establishing goals and priorities • Identifying the dimensions and the attributes of a problem • Providing forecasts • Clarifying positions and delineating differences between group members • Gathering information from a group whose members do not meet fact-to-face and wish to retain their anonymity

  6. Description • Delphi is a method in which individuals focus on and debate issues anonymously. • Typically conducted by mail or e-mail utilizing several rounds of questionnaires. • Results of each round are collected, collated and analyzed by a design team. • Questions for the next round are based on the analysis process. • Generally provides convergence of opinions, but may provide the basis for disagreement.

  7. Advantages within Delphi • Anonymity • More accurate representation of an individual’s feelings • No group meetings are required. • A large heterogeneous group may participate on an equal basis. • Allows participants to be geographically scattered.

  8. Limitations within Delphi • Time may eliminate Delphi as a possibility. • Is not useful for individuals who have difficulties reading or writing. • High participant interest and commitment is assumed or the quantity and quality of responses will decrease with each round. • By design Delphi does not allow for instant communication or intellectual stimulation.

  9. Required Resources • Level of Effort – design team requirements • Skill Level – questionnaire written free of bias. • Time Required – six weeks to complete 4 rounds.

  10. Inputs • Respondents should: • Have special experience or knowledge to share. • Represent a cross-section of opinions. • Be motivated to participate. • Questionnaire should: • Be as short as possible • Be adapted to the language most familiar to the participants area of expertise • Elicit useful responses at the level of abstraction required

  11. Tool Output • Is generally a convergence of opinion. • Frequency distribution • Ranking of responses to a particularquestion.

  12. Schedule for Delphi Delbecq, et al. (1975)

  13. The Recipe • Develop the basis for a Delphi • Design Questionnaire #1 • Solicit responses for questionnaire #1 • Analyze questionnaire #1 • Design questionnaire #2 • Solicit responses for questionnaire #2 • Analyze questionnaire #2 • Design questionnaire #3 • Solicit responses for questionnaire #3 • Analyze questionnaire #3 • Design questionnaire #4 • Solicit responses for questionnaire #4 • Analyze questionnaire #4 • Closure

  14. Design Team Size • Large = 12 or more people. • Medium = 2 – 12 people. • Individual

  15. Large = 30 or more people. Medium = 10 to 30 people. Small = Under 10 people. Audience Size

  16. Theory • Arguments have been made to support the claim that the Delphi method is superior to conventional uses of groups in problem solving or forecasting. (Gordon and Helmer 1964)

  17. Journal Article • Journal of Agricultural Education Article Utilizing the Delphi Method
