In today's economy, it is no longer business versus business, but rather supply chain versus supply chain. To compete, supply chain members must learn to seamlessly integrate, grow, and develop business functions. Traditional quality management practices have been and will continue to be used to address many of these supply chain integration issues. Effective supply chain management (SCM) and quality management (TQM) has become a potentially valuable way of securing competitive advantage competition is no longer between organizations, but among supply chains. This research conceptualizes and develops six dimensions of SCM and TQM practice (strategic supplier partnership, customer relationship, quality of information sharing, customer focus, top management leadership, and process management) and tests the relationships between SCM and TQM practices, and competitive advantage. Quantitative methods research design explanatory research approach was chosen to conduct the research. Data for the study were collected using five point likert scale self-administered survey questionnaire from 4 organizations. 213 workers were selected by stratified sampling technique from 4 departments. The relationships proposed in the framework were tested using multiple linear regression and correlation coefficient. The results indicate that higher levels of SCM and TQM practice can lead to enhanced competitive advantage.
