Delphi technique
noun [ S ]
MANAGEMENT ukus(also Delphi method)a method of collecting opinions about the future and judging how likely a future event or situation is. Experts answer a list of questions without discussing them with each other, look at each others' answers, and change them until a consensus is reached (= a situation where they all agree):
The Delphi technique is a structured approach for reaching a consensus judgment among experts about future developments in any area that might affect a business.
One advantage of the Delphi technique is that participants are not influenced by the dynamics of a group discussion, in which people meet face to face.
