Structural equation modelling the causal effects of ISO 9001 registration efforts

摘要

Effective construction research requires proper application of social science research methods. The use of proper statistical analysis is crucial and there is a need to perform multivariate analysis in order to eliminate spurious relationships. Structural equation modelling (SEM) is increasingly being applied for construction research. From a nationwide survey carried out from 14th February to 30th May 2008 on all key players in the Malaysian construction value chain with ISO 9001 certifications, this paper proposes to classify the benefits gained from ISO 9001 registrations into three categories, namely, company competitiveness, customer satisfaction and business performance. It also reports on the statistical procedures taken and the findings from SEM the causal effects of ISO 9001 registrations efforts. Key elements in the application practice and reporting of SEM are presented. The impact of construction research work can only have a reasonable result if there is consistency and repeatability for the further advancement of construction management research.
