Rejuvenate Six Sigma and Lean:An Inquisitive Approach

Six Sigma and Lean are the recent developments in continuous improvement methodology that have been popularized by several high-profile companies. The success and complementary nature of these methodologies has led to their combination into a single methodology, commonly called "Lean Six Sigma". A Company we studied uses Six Sigma to constrain improvements in product quality and achieved significant bottom-line results over several years. Recently, the company incorporated Lean principles to confront ivaste and cycle time, and witnessed additional improvements. But the company has noiv encountered cycle time and waste problems for which Lean approaches are not working. By combining Six Sigma and Lean, Six Sigma exclusively to perk up quality and Lean exclusively to improve process flow by reducing waste and cycle time, the improvement must come on all fronts: quality, cost, delivery, customer satisfaction and more. In this paper a comprehensive approach of Six Sigma and Lean with a case study is demonstrated.
