Description:
The Delphi group approach is a technique for gathering data that is similar to focus groups. Its value is that unlike focus groups, Delphi groups do not have to physically meet. The Delphi technique is a method of generating ideas and facilitating consensus among individuals who have special knowledge to share, but who are not always in contact with each other. A Delphi study carefully selects individuals who have knowledge necessary to analyse a specific problem.
