The art of the Delphi technique: highlighting its scientific merit

Abstract

The initial use of the Delphi technique was forecasting in order to be able to plan ahead. More recently the Delphi technique has been used as a constructive method in facilitating controlled, rationale group communication to develop knowledge for decision-making. Although the Delphi technique is widely used, its scientific merit is questioned. This article illuminates the application, limitations, value and scientific merit of the Delphi technique. The subsequent articles illustrate the application of the Delphi technique.
