Qualitative delphi method: A four round process with a worked example

Abstract

The Delphi Method was originally designed to collect data from a panel of experts to aid in decision making in government settings. Delphi has been described as a qualitative, quantitative, and mixed-methods approach. The anonymous collection of narrative group opinion coupled with the tightly structured nature of the process and quantitatively described results renders the approach difficult to situate in a methodological category. The purpose of this article is not to settle the debate. Rather, the aim is twofold: to present a modification of Delphi that is definitively qualitative, and to provide a worked example to demonstrate the proposed method.
