Details for «Delphi Survey»
A Delphi Survey is a series of questionnaires that allow experts or people with specific knowledge to develop ideas about potential future developments around an issue. The questionnaires are developed throughout the process in relation to the responses given by participants. Delphi surveys can be carried out face to face, online or by post. In online versions participants are given their own login and password to access the site. The technique aims to derive the benefit of the opinions of a group of experts while avoiding the disadvantages of 'group think' and group dynamics where certain individuals dominate the discussion.
The first questionnaire either asks the participants to individually identify issues and generate as many ideas as possible or to answer more closed ended questions such as the likely dates for specific developments.
The second questionnaire anonymously feeds back all the ideas and forecasts gathered in the first round to all participants. This questionnaire also provides space for participants to refine each idea, comment on their strengths or weaknesses and to suggest new ideas.
An additional questionnaire then summarizes the input from the second questionnaire and asks for additional clarification, strengths, weaknesses, and new ideas. This stage can be repeated as many times as necessary until consensus on key points is reached.
The end product is either a consensus amongst the participants on likely and possible future developments or a wide range of possible developments and their relative strengths and weaknesses.
