This study explores the integration of Lean and Six Sigma quality techniques in Industry 4.0, focusing on barriers and enablers. Industry 4.0 has transformed manufacturing through digitalization, automation, and data analytics. However, effective integration of quality improvement methodologies is crucial for fully harnessing its potential. The review provides an overview of Lean and Six Sigma, highlighting their strengths in driving operational excellence. It discusses challenges faced in integrating these techniques, including technological complexities, organizational culture, skill gaps and resistance to change. A framework for strategic integration is presented, encompassing leadership commitment, employee engagement, collaboration, and advanced technologies. Practical strategies and best practices for overcoming barriers and leveraging enablers are discussed, offering actionable insights. Embracing the strategic integration of Lean and Six Sigma in Industry 4.0 enhances operational efficiency, reduces defects, and improves customer satisfaction. This manuscript serves as a valuable resource for managers, practitioners and researchers navigating the confluence of barriers and enablers in achieving quality excellence in the digital age.
