Impact of Six-Sigma DMAIC approach on Manufacturing Industries

Satish Kumar

The concept of Six-Sigma has dominated the management scene for some decades. Six-Sigma is a rigorous, disciplined, data-driven methodology that was developed to enhance product quality and company profitability by improving manufacturing and business processes. Many organisations all over the world have tried to use Six-Sigma DMAIC (Define, Measure, Analyze, Improve, and Control) approach and its tools to get optimised organisational achievements. The present work is an attempt to study the impact of Six-Sigma DMAIC approach in manufacturing industries of Ludhiana. This study is to explore the level of usage and level of difficulty of different tools of DMAIC approach. Barriers in implementing Six-Sigma DMAIC approach and the benefits achieved after successful implementation of DMAIC approach have also been identified. A well designed questionnaire has been used to collect data from 23 manufacturing industries. The results from the analysis of data have shown that, the manufacturing organizations have less educated man power (Mean=2.8260 significant at 5% level) and also they are lacking in to provide adequate training to them for effective implementation of Six-Sigma tools. Furthermore, the results have shown that maturity phase of DMAIC approach enhances the improvements as compared to initial and developing phase, yet it can be concluded that Six-Sigma DMAIC approach is still growing in manufacturing organizations. Also, the results of correlation analysis indicate that DMAIC approach is significantly used to improve the quality (r=0.443122 significant at 5% level) of product.
