The Delphi Technique
Essentially, Delphi is the name given to a set of procedures for eliciting and refining the opinions of a group - usually a panel of experts (Brown, 1968). It is a way whereby a consensus and position of a group of experts is reached after eliciting their opinions on a defined issue and it relies on the "informed intuitive opinions of specialists" (Helmer, 1994). This collective judgment of experts, although made up of subjective opinions, is considered to be more reliable than individual statements and is thus more objective in its outcomes (Masini, 1993). As Linstone and Turoff (1975:3) write, "Delphi may be characterized 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."
Although there are a range of Delphi techniques now in use and adapted for various needs, it is still possible to talk of a broad procedural outline that they follow. Firstly, the subject of the study is circulated to the participants in an unstructured manner to enable them to comment on the issues in question. This material is then synthesized by the monitoring team (one or more people coordinating the study) and distributed to the participants in a questionnaire format. It needs to be mentioned here also that this first round is very often circumvented by the issue being explored comprehensively by the monitoring
