In this quickly evolving digital era, every industry is undergoing digital revolutions, which have an impact on business. This investigation aims to look into the effects of the digital supply chain on performance (in regards to product quality and cost reduction performance), with particular emphasis on the automobile industry in Indonesia. Additionally, the analysis investigates the moderating effect that lean practices have on the link between these factors. A total of 120 questionnaires were gathered, and analysis was performed using the PLS-SEM method. The findings indicate that the digital supply chain has a considerable impact on product quality and cost reduction performance. In addition, the results indicate that lean practices moderate the relationship between the digital supply chain and product quality performance, but not cost reduction performance. This finding contribute to the comprehension of supply chain management bridging the knowledge gap in the digital supply chain. Particular attention has been paid to the previously unstudied influence of operational performance within the framework of the automotive industry.
