Six Sigma is an organized & systematic method for strategic process improvement that relies on statistical & scientific methods to reduce the defect rates and achieve significant quality up- gradation. A case study is carried out for a foundry, where Six Sigma methodology is implemented for the defect reduction. The optimized parameters are considered to perform the practical run for the differential housing castings. Proposed techniques optimized control factors, resulting in superior quality and stability. This study aims to implement a novel approach to improve the quality (reducing the defects) of a foundry by Six Sigma methodology on the selected projects.
