Apart from the introduction the proceeding sections of the paper discusses the theoretical and conceptual basis on what constitutes Delphi, Delphi questionnaire design, the administration of the Delphi survey, Delphi panel selection, analysing Delphi results, and finally a brief conclusion with vital points to be consider in using Delphi as a Decision Analysis tool.
