This study examined the impact of digitalization on total quality management (TQM) practices and examines how both digitalization and TQM practices influence supply chain performance (SCP) within the manufacturing sector in Jordan, a developing country. Using the resource-based view and dynamic capabilities theory, the study conceptualizes digitalization as a dynamic enabler that reinforces internal quality capabilities. Data were collected through a self-administered survey targeting managers in Jordanian manufacturing firms, resulting in 74 valid responses. Established measurement scales were used, and the data were analyzed using multiple linear regression via SPSS. The findings reveal that digitalization significantly enhances the implementation of TQM practices, particularly by improving process visibility, data integration, and quality control. Amongst the six TQM dimensions examined, only process management and employee involvement demonstrated a significant positive impact on SCP. Additionally, digitalization was found to have a direct and positive effect on SCP, reinforcing its strategic role in enhancing responsiveness and efficiency in supply chains. The study contributes to literature by incorporating digital transformation with quality and supply chain in the context of Jordan as a developing economy. It additionally offers actionable suggestions for managers in pursuit of aligning digital initiatives with quality-driven practices to improve supply chain outcomes.
