The Implications of Digitalization in Improving Manufacturing Operational Performances

Abstract

The rapid rise of Industry 4.0 has positioned digital technologies as essential tools for enhancing manufacturing performance. However, empirical evidence indicates that these technologies often fail to produce sustainable improvements. This thesis explores the paradox of Digitalization in manufacturing, arguing that digital tools alone are insufficient to deliver lasting performance gains. Through a historical and conceptual analysis, the study demonstrates that technological revolutions have historically fallen short when not accompanied by human development, organizational learning, and managerial alignment. Drawing on the principles of the Toyota Production System, Lean thinking, and the Shingo Model of Operational Excellence, the thesis positions Digitalization as a supporting element within a broader system of Continuous Improvement. This article also suggests that successful Digital Transformation is more likely when organizations pursue purpose driven and incremental adaptation rather than disruptive, tool centered strategies. Ultimately, the study advocates for a principle-based approach in which Digitalization is integrated into human-centered systems that prioritize learning, alignment, and sustained excellence
