Supporting evidence — 5 representative gaps

• Using the delphi technique in institutional planning (1983) · New Directions for Institutional Research · cited 31× · doi

  The Delphi technique has limitations, such as assuming experts are objective and can make sound deductions about the future. There is a need to understand the differences between forecasting and other uses of the Delphi technique.

• Using the delphi technique in institutional planning (1983) · New Directions for Institutional Research · cited 31× · doi

  The Delphi technique assumes experts are objective and can make sound deductions about the future. The technique has limitations, such as the number of experts required and the response scale used. The technique may not be suitable for all planning phases or situations.

• The Reliability and Convergence of the Delphi Technique (1978) · The Journal of General Psychology · cited 19× · doi

  The reliability and convergence of the Delphi technique have not been thoroughly examined. Prior work has reported reliabilities for competing Delphi technique panels, but has not examined the use of the technique in identifying successful vocational education programs.

• The methodological worth of the Delphi forecasting technique (1975) · Technological Forecasting and Social Change · cited 182× · doi

  The Delphi method's reliability and validity issues need to be addressed. There is a lack of administrative standards and methodological expertise in Delphi research. Alternative approaches to forecasting need to be considered.

• The methodological worth of the Delphi forecasting technique (1975) · Technological Forecasting and Social Change · cited 182× · doi

  The lack of standardization in the Delphi method can lead to reliability issues. The method's validity is also questionable due to pressures that can undermine predictions. The customarily weak background in social science methodology of most Delphi experimenters can lead to poor research strategies.
