Investigating the impacts of ISO 9001 certification on lean manufacturing and supply chain relationship: an empirical analysis

Purpose This research examines the impacts of ISO 9001 certification on lean manufacturing (LM), supply chain relationship (SCR) and their sub-constructs Design/methodology/approach Data was collected from 516 manufacturers in Thailand. Structural equation modeling was applied to analyze the hypotheses Findings It was found that ISO 9001 certification significantly affects overall LM, its facility and quality sub-constructs, overall SCR, its supplier coordination, customer collaboration and customer coordination sub-constructs. ISO 9001 has insignificant impacts on production, purchasing and distribution of LM, and supplier collaboration of SCR. Originality/value This study is one of the first research to present insights into the impacts of ISO 9001 as a certificate rather than as a set of management practices on LM, SCR and their sub-constructs
