Delphi Process

The Delphi technique maintains anonymity for participants and avoids confrontation by eliminating face-to-face interaction (Dalkey and Helmer 1963). Standard implementation of the Delphi method employs questionnaires to which each member of the group anonymously responds. Questionnaires are repeatedly administered to group members for revision, intermixed with feedback of questionnaire summaries until some convergence of opinion has been reached. The absence of group discussion avoids voice dominance by position or persuasiveness, and reduces group pressure to conform (von Winterfeldt and Edwards 1986), although the benefits of group synergy are sacrificed in the process.
