ACCOMPLISHMENTS AND CONTRIBUTIONS OF SIX SIGMA APPROACH FOR SUSTAINABILITY OF SERVICE AND MANUFACTURING INDUSTRY IN TERMS OF QUALITY IMPROVEMENT

Abstract

Purpose- This study investigates the development, advantages, customer satisfaction, and problems of six sigma principles, provides a brief introduction of the six-sigma organizational structure and its application in industry implementation, and highlights the major elements impacting successful six sigma deployments. In addition, the objective of this research is to evaluate the fundamental ideas of six sigmas, its advantages, and effective implementation methodologies. Methodology- Quality Management-Process improvement is already a critical systematic process for gaining a competitive edge and improving performance. Whereas Six Sigma might have been initially established with manufacturing techniques, it is now employed through service organizations and service operations in practically every industry and by some service sectors (e.g., transportation, telecom, and healthcare) to increase profitability and performance. In addressing critical challenges, business managers implement Six Sigma in business marketing, financial, operations management, regulatory, and employee relations operations. Generally, the Six Sigma approach has been employed in the industrial sector of industry. Findings- This research, in terms of direction, includes exemplary practices/applications from the service industry and manufacturing sector, as well as other industries (e.g., transportation and mobile communications-telecommunications) that are pioneers and entrepreneurs-innovators in applying the procedures via quality function deployment. We provide insights acquired from past successes. The work incorporates the principles acquired from outstanding six sigma enterprises, discusses the principles of managerial position and appropriate six sigma application deployment, and examines future enhancements to the six sigma method. Conclusion- Six sigma concepts and practices that are beneficial could flourish through constantly improving the management structure. According to the findings of this study, the principles of effective application comprise higher management endorsement and engagement, strategic alignment, skills development, platforms, and connections to personnel management efforts- initiatives.
