Infosys’ “Reimagining Lean in the Digital Era” explores how manufacturers are evolving from traditional Lean principles to “Lean 4.0” by integrating technologies such as AI, IoT, edge computing, advanced analytics, digital twins, and AR/VR. The report argues that while Lean’s focus on waste reduction and continuous improvement remains essential, digital technologies enable real-time visibility, predictive decision-making, smarter automation, and greater operational agility. Key benefits include improved quality, reduced waste, enhanced workforce productivity, faster response to disruptions, and stronger regulatory compliance. The paper highlights digital tools such as e-Kanban, digital Andon boards, and digital Gemba walks, while emphasizing that successful transformation requires workforce upskilling, cultural change, and strong leadership. Lean 4.0 is positioned as a path to greater resilience, competitiveness, and sustainable growth in modern manufacturing.
