Abstract

This study investigates the impact of supplier relationships—one of the core dimensions of Total Quality Management (TQM)—on performance improvement in the National Company for Mills and Feed. A descriptive–analytical approach was adopted, and data were collected through a questionnaire distributed to 200 employees, of which 184 valid responses were analyzed. Reliability analysis showed high internal consistency, with Cronbach’s Alpha reaching 0.873 for the supplier relationship dimension and exceeding the 0.70 threshold for the overall instrument. Descriptive results indicated that supplier relationship scores ranged between 2.92 and 3.36, while performance improvement scores ranged between 2.62 and 3.04—both falling within the moderate level. Regression analysis revealed a strong and statistically significant relationship between supplier relationships and performance improvement, with a correlation coefficient of R = 0.815 and a coefficient of determination of R² = 0.665, indicating that supplier-related practices explain 66.5% of the variance in performance. The direct effect was also high (β = 0.908, Sig = 0.000).

These findings highlight the critical role of strengthening supplier collaboration, improving information sharing, and enhancing evaluation mechanisms in boosting product quality and operational efficiency. The study recommends adopting strategic, long-term supplier partnerships to support effective TQM implementation and achieve higher levels of competitiveness and sustainable performance.
