The Delphi technique: a method for testing complex and multifaceted topics

Purpose – The purpose of this paper is to provide project management (PM) students with an example of the Delphi research approach that was applied to a recent doctoral research thesis. The objective is to provide both a description of the approach and an explanation of how it was successfully applied so that researchers in PM may become more aware and expand their perceptions of methodological options available to them.Design/methodology/approach – The paper sets out a literature review of the Delphi approach and explains this research method as it was experienced as a research tool. The paper also provides reflection on the experience of being a researcher undertaking a doctoral study.Findings – The Delphi approach is one of many that may be selected for researching PM issues and problems. It is appropriate for researching complex issues where larger scale quantitative “hard data” fails to unearth richness in tacit knowledge to help the research understand subtle expert opinion.
