Digital transformation driven by Industry 4.0 technologies has become a critical enabler for improving operational performance in large-scale manufacturing industries. However, empirical evidence demonstrating measurable performance improvements through integration of digital technologies with operations management systems remains limited, particularly in continuous manufacturing environments. This study empirically examines the impact of Industry 4.0–enabled operations management systems on manufacturing performance using real production, quality, and equipment effectiveness data. A longitudinal case-based research design was adopted, comparing operational performance before and after the implementation of digital operations management systems. Performance indicators included monthly production output, rejection percentage, and Overall Equipment Effectiveness (OEE). Results show a substantial increase in production output from 416,667 tons/month to 500,000 tons/month, a sharp reduction in rejection percentage from 0.05% to 0.01%, and a significant improvement in OEE from 77% to 85% following digital transformation. The findings provide strong empirical evidence that digital transformation, when embedded within core operations management systems, leads to significant and sustainable performance improvement. The study contributes to operations management and Industry 4.0 literature by validating a data-driven performance improvement framework applicable to large-scale manufacturing industries.
