The validity of the classical Delphi applications for assessing the industrial sustainability-correction factor: an example study

Purpose The study aims to build up knowledge for collateral exploration of the classical Delphi survey method for assessing the industrial sustainability-related correction factor using a real field study in Nigeria. Design/methodology/approach The paper elicits the character and the operational approaches using an example study to provide a critical review of the method. It estimates the correction factor for appraisal purposes by transforming expert opinion into a valid group consensus. Findings The work considers the specific parameters of the method, design and analysis for interpretation to prove the reliability and the validity for the research results. Moreover, it emphasises that the validity of the traditional Delphi research demands cautious theoretical and practical applications by the coordinating researcher. The paper establishes the current validity and effectiveness of the classical Delphi method of foresight and streamlines their efficient implementation for theory building despite its numerous weaknesses. Originality/value It explores desirable futures for the method while analysing what is possible and probable.
