Abstract: This paper introduces a novel and comprehensive framework for optimizing process improvements in high-volume manufacturing plants. As industries worldwide face escalating pressures for cost reduction, improved efficiency, and enhanced quality, Lean Manufacturing, Six Sigma, and Kaizen have emerged as critical tools for driving operational excellence. While individual methodologies are well-established, their integration into a unified framework that can scale for high-volume operations is largely unexplored. This research focuses on developing a flexible, adaptable, and scalable process improvement framework that integrates Lean principles, Six Sigma methodologies, and Kaizen strategies.
