The Delphi method, also known as the Delphi technique or Delphi forecasting, is a forecasting or estimating method based on a discussion by a group of experts. It is a structured communication technique originally developed as a systematic, interactive forecasting method which relies on a panel of experts. It was originally designed for 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; then review each others' answers and change them until a consensus is reached (which is a situation where they all agree).
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. Face-to-face meetings can be greatly enhanced with the use of the Delphi technique when it's used as part of the meeting, as Delphi process will help eliminate the social dominance and influence prevalent in live group meetings.
The Delphi Method is widely adapted and used worldwide in all industry sectors and business areas, but is especially useful for public policy making, and establishing guidelines on standard practice of care or quality indicators.
