9. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 9 Guidelines for Determining Six Sigma Metrics b Consider ways to measure Service as well as Output factors. b Practice continuous improvement of the measurements. b Set measurement priorities that match resources (Prioritize for maximum potential gain.) b Stop measurements that are not needed or useful.

10. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 10 Selection of Six Sigma Improvement Projects b There is a gap between current and desired/needed performance. b The cause of the problem is not clearly understood. b The solution isn’t predetermined, nor is the optimal solution apparent.

11. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 11 Implementation of Six Sigma Improvement Projects b Start small; don’t go for large scale changes at first b Select several well-defined projects b Expand projects after early successes are accomplished

12. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 12 Lean Enterprise b General term for the application of lean principles b Widespread success in manufacturing during past 15 years b More recently - applied to transactional endeavors - billing, customer service, etc. b Represents a culture change

13. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 13 Evolution of Lean Manufacturing b Total Quality Management b Toyota Production System b Six Sigma Process Improvement b Theory of Constraints b Value Stream Mapping b Womack and Jones - Lean Thinking b Rother and Shook - Learning to See

ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 27 Propositions 2 and 3 b Lean and Six Sigma are inextricably linked as partners in cost reduction, lead time, and quality improvement. b Lean produces remarkable successes -- but only in small pockets of activity b (Lean Six Sigma, Michael George)

28. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 28 Proposition 4 b Lean and Six Sigma should be applied together because A stand-alone Six Sigma program cannot dramatically increase process speed or decrease invested capitalA stand-alone Six Sigma program cannot dramatically increase process speed or decrease invested capital A lean enterprise that focuses on eliminating waste will not bring a process under statistical controlA lean enterprise that focuses on eliminating waste will not bring a process under statistical control

29. ETM 627 Fall 2008Dr. Joan Burtner, Associate Professor of Industrial Engineering Slide 29 Proposition 5 b b Some people believe lean enterprise methodologies must be completed before Six Sigma gains can be maximized. b b James Bossert, July 2003 “Lean and Six Sigma--Synergy Made in Heaven” Quality Progress.
