Item Quality improvement through systematic approach-six sigma(The Journal of Engineering Education, 2011) Reosekar, Ravi ShrikrishnaSix sigma a statistically based quality improvement methodology, leads to breakthrough in product / process quality,customer satisfaction and productivity. The concept of six sigma was pioneered at Motorola in the 1980's and the concept was to reduce the number of defects to as low as 3.4 parts per million opportunities.Item Design and development of Six Sigma implementation framework for Indian industries(IJEBEA, 2013) Reosekar, Ravi ShrikrishnaSix Sigma has emerged as a powerful tool in quality management over the recent years and the approach is widely used across all sectors of manufacturing, service logistics and health & hospitality. In today’s competitive environment to sustain global competition means to be the best in the field at each competitive priority and to demonstrate industry best quality improvement practices like six sigma. A little work has been done in the area of framework of six sigma implementation but none of the existing frameworks was found to be suitable for the Indian scenario, and the completeness of existing Indian six sigma frameworks was also found to be lacking. Hence this paper aims to focus on the development of a new framework for providing direction and guidance for implementation of six sigma in Indian scenario. Total 67 frameworks of six sigma implementation as proposed by various researchers, consultants, international agencies and individuals were indentified through literature review. Comparative analysis of these identified frameworks was carried out and a new framework is suggested after considering domain knowledge of six sigma and through discussion with experts. Some unique elements/attributes of six sigma were identified through comparative analysis which represent/forms the pillars of six sigma.Item Six Sigma methodology: a structured review(Emerald, 2014-10) Reosekar, Ravi ShrikrishnaThe main aim of the present study is to explore field of Six Sigma and discover the limitation of the present research work. The study also tries to find emerging aspects, trends and future directions and explore unfocused areas of Six Sigma. The present study involves an analysis of 179 research articles published from 1995 to 2011 in 52 selected reputable journals.
