Delphi technique
Definition:
A method of soliciting and aggregating the opinions of a group of experts to derive a consensus view concerning the time-scale during which speculated future developments may occur (or the probability that they will have occurred by a particular date). The technique minimizes socio-psychological influences by keeping individual responses anonymous. It proceeds by means of a programmed sequence of interrogations (conducted by questionnaire) interspersed with the feedback of information describing the consensus view.
