  • (written as Delphi Method)
    A systematic method of obtaining a collective opinion, usually of a group of experts, in the absence of more reliable assessments (of, say, effectiveness or some other quantitative measure or indicator). The basic method involves a facilitator soliciting opinions, which are then fed back anonymously to the group, whose members may then revise their opinions and feed them back again. After a few rounds, the facilitator usually averages the opinions.


  • noun a method of forming strategies by soliciting individual estimates on the time-scale of projected developments and then inviting further estimates on the basis of all those already made until a consensus is reached
