Use of Shainin Tools for Simplifying Six Sigma Implementation in Qms/iso Certified Environment– an Indian Sme Case Study

Six sigma for small-and medium-sized enterprises (SMEs) is an emerging topic among many academics and Six Sigma practitioners over the last two to three years. Very few studies have been reported about the successful applications of Six Sigma in SMEs. Main objective of this paper is to examine the extent of usefulness of a simpler but not very frequently used methodology known as the Shainin methodology for simplifying the implementing Six Sigma. To confirm whether Six Sigma implementation is simplified, this paper highlights the comparison of three DOE approaches viz. Classical, Taguchi and Shainin methodology. A case study based research work done in ISO certified Indian SME, concludes that, Six Sigma implementation process can be simplified by using Shainin tools and proper use company's ISO/QMS. 1. INTRODUCTION In recent past, academicians, practitioners and organizational researchers have recognized that the Quality Management System (QMS) process and the Six-Sigma process are disciplines that have a powerful potential to affect an organization's ability to compete within an increasingly global and dynamic marketplace (Falshaw et al., 2006). QMS certification (such as ISO 9000, TS 16949) demonstrates the capability of an industry to control the processes that determine the acceptability of the product or service being produced & sold. These, traditional QMS are having some limitations like methodological assistance etc. (Bewoor and Pawar, 2008). But new QM methods continue to grow (Xingxing Zu et. al., 2008) for example, Six Sigma, which is ''an organized and systematic method for strategic process improvement and new product and service development. Six Sigma relies on statistical methods and the scientific method to make dramatic reductions in customer defined defect rates'' (Linderman et al., 2003). Since its initiation at Motorola in the 1980s, many companies including GE, Honeywell, Sony, Caterpillar, Johnson Controls etc. have adopted Six Sigma and obtained substantial benefits (Pande et al., 2000). Spectacular development of an organizational performance due to Six Sigma implementation many companies are reported in the published literature. Antony and Banuelas (2002) presented the key ingredients for the effective introduction and implementation of Six-Sigma in manufacturing and services organizations as: Management commitment and involvement, Understanding of Six Sigma methodology, tools, and techniques, Linking Six Sigma to business
