Tham khảo tài liệu 'six sigma projects and personal experiences part 3', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Lean Six Sigma 21 Lean is a business transformation methodology which was derived from the Toyota Production System TPS which focusses on increasing customer value by reducing the cycle time of product or service delivery through the elimination of all forms of waste and unevenness in the workflow. Lean Six Sigma is a disciplined methodlogy which is rigorous data driven result-oriented approach to process improvement. It combines two industry recognized methodologies evolved at Motorola GE Toyata and Xerox to name a few. By integrating tools and processes of Lean and Six Sigma we re creating a powerful engine for improving quality efficiency and speed in every aspect of business. Lean and Six Sigma are initiatives that were born from the pursuit of operational excellence within manufacturing companies. While Lean serves to eliminate waste Six Sigma reduces process variability in striving for perfection. When combined the result is a methodology that serves to improve processes eliminate product or process defects and to reduce cycle times and accelerate processes Lean and Six Sigma are conceptually sound technically fool proof methodologies and is here to stay and deliver break through results for a long time to come. This chapter discussed the history of Six Sigma and Lean thinking and important steps in implementing Lean Six Sigma like DMAIC methodology. Some of the important Six Sigma and Lean tools were discussed with examples which will be of help to a Six Sigma practitioner. Three case studies were presented which shares experiences on how Six Sigma implementation had helped them to improve their bottom line by removing variations in the processes and eliminating defects and reducing cycle time. 11. Acknowledgment We have presented two case studies on Six Sigma implementation by Ms. Honeywell International Inc and Xerox Global Services we sincerely acknowledge for their pioneering work on quality improvement measures by them for improving bottom line of their
