The research employs a positivist philosophy with a descriptive and survey-based design, combining quantitative data from 50 Ministries, Departments, and Agencies (MDAs) and staff from three indigenous automobile companies. A structured questionnaire was used to collect data, and multiple regression and correlation analyses were conducted using SPSS to explore the relationships between raw material sourcing, product design, cost efficiency, and consumer loyalty. Findings from this research highlight the strategic importance of SCM in achieving cost efficiency through efficient raw material sourcing and in building stronger customer loyalty via sustainable product design.
