One of the Risk Identification technique, used to gather information.
In Delphi Techique, the participants dont usually know each other, nor they have to be present at the same location.
A Moderator or project Manager will usually communicate with the participants to identify the Risk and consolidate all the risks identified by them.
This is one of the best technique of Risk identification, as the participants (not necessarily be only from project team) would not be influenced by other participants, as they usually do not know each other.
