Title: Opinion-Based Research: Lessons Learned from Four Approaches
Abstract: Selecting an appropriate research method is a critical step in any rigorous research effort. The selected research methodology impacts the data collected, the scope of inference, and the ability to draw defendable conclusions. Many times the nature of the construction industry and the sensitivity of information limit researchers' ability to conduct experimental, empirical, or observational studies that rely on objective data. In such circumstances, alternative methods of research that utilize expert judgment and opinion may be considered. Several techniques such as group-brainstorming, the Delphi method, the Nominal Group Technique, and surveys may be appropriate. However, selecting one or more of these research methods depends largely on the nature, resources, and limitations of the research study. This paper reviews four major approaches of obtaining expert opinion, describes lessons learned on four independent, major studies, and provides a framework to consider when selecting a specific method given project characteristics. The resulting flowchart can be used to aid in selection of a research method given the specific characteristics of the study such as limitations in time and funding, desired information, and location and availability of participants.
