Supply Chain Management (SCM) competitiveness is achieved based on process efficiency. To improve efficiency, we depend greatly on knowledge acquisition and utilisation in the area of Knowledge Management (KM). KM is particularly relevant to every stage in SCM in order to make accurate and timely decisions that are critical to the firms' effectiveness and efficiency in SCM. At the same time, the Total Quality Management (TQM) concept proposes a system to improve the efficiency and productivity. This study makes a significant contribution by developing a proposed model as a methodological example which can be useful for tracking the degree of KM and TQM effects on SCL in both the service and the manufacturing industry.
