The effect of the relationship between total quality management and supply chain management on operational and firm performance

Nowadays, global competition is very intense and this forces companies to adapt various management techniques in order to cope with competition or to overcome them. Total Quality and Management (TQM) and Supply Chain Management (SCM) are among the first to come to mind among these management techniques. A literature review for this study showed that there are many studies conducted separately about these techniques but there are few studies showing their relationship with each other and their joint effects on performance. This study was carried out to contribute to this gap in the literature. More specifically, this study aims to demonstrate the impact of TQM practices on SCM applications, the impact of TQM practices and TQM practices on operational performance, and finally the relationship between operational performance and operational performance. For this purpose, data were collected from 102 production companies operating in the Eastern Marmara region by using the survey technique and the data were analyzed by statistical techniques such as item purification, factor analysis and structural equation modeling. The results showed that TQM practices had a positive effect on SCM practices and these two managerial approaches had jointly a positive impact on operational performance. It was also found that operational performance had a positive impact on buisness performance. It is expected that decision makers who use these two management approaches together will achieve a significant advantage in competition.
