Abstract

This paper discusses the implementation process of Six Sigma in three Indian manufacturing industries. All the five steps i.e. define measure, analyze, improve, and control (DMAIC) were implemented successfully. Rejections were reduced to the extent of 3.4ppm from the past level of approx. 4000ppm. Productivity value based on ratio of total output to total input was calculated before and after the implementation of Six Sigma Methodology. The results show an upward trend in productivity values in all three manufacturing units.
