The Yellow Belt’s primary focus is to facilitate local-level improvement that targets reducing waste. We are super pumped that you are nerding out with us and selected us to be your mentor and advisor as you embark on your learning journey. Many of the topics we discuss in this learning experience are publicly available. If you don’t find what you are looking for in our training, check out some of the other resources that exist out there. Just to level set, this is an overview course. It is a starting point. If you want to grow your understanding of Lean Six Sigma you are going to have to be resourceful and do research and learning outside of this curriculum. If this stuff wets your whistle, then we'd encourage you to participate in our more advanced learning experiences. Lean Six Sigma is a huge Body of Knowledge and we are just scratchy the surface of the nerdy things that exist within the expansive improvement world. 4 HISTORY AND BACKGROUND OF LEAN SIX SIGMA ORIGINS OF LEAN SIX SIGMA The origins of Lean thinking and Six Sigma can be traced back over a century as industry tried to move from craft production to mass production, and later to automation. The term “Six Sigma” was coined at Motorola Corporation in 1980 as they embarked on their quality improvement journey. The term “Lean” was coined by John Krafcik in 1988 in his article “Triumph of the Lean Production System”. An article written about Toyota. 5 SIX SIGMA GURUS Walter A. The Father of Statistical Quality Control. Shewhart Economic Control of Quality of Manufactured Product (1931) Proposed the use of control charts for monitoring processes, bringing together the functionality of statistics, engineering, and economics. Pioneers the Plan-Do-Check-Act (PDCA) cycle. W. Edwards In the 1950’s, Deming worked closely with Japanese businesses during the Deming post WWII rebuilding efforts. During that time, Deming introduced statistical control methods to Japanese manufacturing. Creates “Deming’s 14 Points of Management” to help highlight how to lead continuous improvement. Joseph M. Introduced the concept of cost of poor quality through “Juran’s Trilogy” - an Juran approach to cross-functional management that is composed of three managerial processes: quality planning, quality control, and quality improvement. Armand V. Introduced the concept of Total Quality Control (TQC), which later became Feigenbaum known as Total Quality Management (TQM), which is an effective system for integrating the quality development, quality maintenance, and quality improvement efforts of the various groups in an organiZation so as to enable production and service at the most economical levels which allow full customer satisfaction. Kauro Introduced cause and effect (also known as the fishbone diagram) to Ishikawa quality management. Introduced the concept of quality circles, which is a volunteer team of workers who are trained to identify, analyze, and solve work-related problems. The objective of the team is to communicate problem areas to management so that quality can be improved. Genichi Taguchi’s Loss Function – stated that loss in value increases as Taguchi variation increases. Used statistical methods to control manufacturing quality, understood that variation caused loss in product value. Bill Smith “Father of Six Sigma”. Combined years of quality improvement efforts to create the practice of Six Sigma. In 1988, leveraged Six Sigma methodology to turn around Motorola’s operations and quality, helping the organization win the coveted Malcolm Baldrige National Quality Award. Mikel Harry SummariZed Motorola’s approach to improvement and packaged as a training curriculum for managers. Founded the Six Sigma Academy in 1994. Key contributor and author of current day Six Sigma practices 6 LEAN GURUS Henry Ford In 1901, founded the Ford Motor Company. Leveraged mass production to bring the Model T to market at an affordable price, which decreased over time. Vehicle price was $825 in 1908, by 1916 the Model T sold for $360. Frederick American mechanical engineer who was one of the intellectual leaders of Taylor the Efficiency Movement. Created the Principles of Scientific Management which highlighted how to divide work equally between managers and workers. This laid the foundation for science behind time motion studies. Sakichi Founder of Toyota and Father of the Japanese Industrial Revolution. Toyoda Developed the concept of “jidoka” (smart automation). Also developed the concept of 5 Why. Kiichiro Son of Sakichi Toyoda. Installed waste reduction principles and Just-In Toyoda Time approaches to help the Toyota Motor Company reduce costs and improve efficiency during its post-WWII rebuilding efforts. Eiji Toyoda Created the “Toyota Way” as a lean culture based on the concept of “Kaizen” and continuous improvement. Taiichi Ohno Japanese businessman who contributed to the creation of Toyota Production Systems (TPS). PopulariZed the concept of Just-In Time (JIT). Created the “Seven Wastes” model to help companies reduce wasteful activities in their operations. Shigeo Considered the world’s leading expert on manufacturing practices and the Shingo Toyota Production System. Collaborated with Norman Bodek to translate Japanese lean training principles into the English language. PopulariZed the concepts of “pull” and poka yoke. James P. The founder and senior advisor to the Lean Enterprise Institute, Inc. which Womack seeks to advance a set of ideas known as lean production and lean thinking, based initially on Toyota’s business system and now being extended to an entire lean management system. John Krafcik Will working at the Lean Enterprise Institute, Inc. John Krafcik coined the term “Lean”. Michael After traveling to Japan to learn Lean, Michael Gorge returned to the USA to Gorge create a successful consulting group, The Gorge Group, providing Lean consulting services. Michael George has authored various Lean Six Sigma books and training resources. 7 BENEFITS OF LEAN SIX SIGMA Lean Six Sigma has multiple benefits. Almost too many to list. Lean Six Sigma is about creating a culture of continuous improvement. A culture in which everyone within the organization is striving for excellence in order to better serve the customer. Lean Six Sigma is about consistently delivering value to the customer, without defects. A process that is performing at Six Sigma will yield a defect-free rate of 99.99966%. This means that per million opportunities, only 3.4 defects would be observed.

Edwards Deming The History ● W. Edwards Deming in the early to mid 1900’s proposed that business processes should be analyzed and measured to identify sources of variations that cause products to deviate from customer requirements. ● He recommended that business processes be placed in a continuous feedback loop so that managers can identify and change the parts of the process that need improvements. The History As a teacher, Deming created a rather simple diagram to illustrate this continuous process, commonly known as the PDCA cycle for Plan, Do, Check, Act*: ● PLAN: Design or revise business process components to improve results ● DO: Implement the plan and measure its performance ● CHECK: Assess the measurements and report the results to decision makers ● ACT: Decide on changes needed to improve the process Perfection: The Deming Cycle (what to do; for improvement) Plan (implement more widely); Operating Efficiency standardise) Act D (it, on a trial o basis; experiment) “Hold the gains” (Standard Work) Study (if it works; the risks; the variation, LEARN!)

  • Quality Guru Series 7. Dr. Shigeo Shingo
    Ley Hill Solutions Newsletter - November 2010 (extract) Quality Guru Series 7. Dr. Shigeo Shingo Dr. Shigeo Shingo was born in Saga City, Japan, in 1909 and was a Japanese industrial engineer who distinguished himself as one of the world's leading experts on manufacturing practices. Among other things, from 1955 he taught seminars in industrial engineering at Toyota for Taiichi Ohno (the subject of the first in our Quality Guru Series). During this time he worked as a consultant for Toyota, a rarity as Toyota did not in general use consultants, and helped develop and publicize the Toyota Production System (the roots of lean manufacturing, lean thinking and Just in Time - JIT). Although Shigeo Shingo did not single-handedly invent the Toyota Production System(a large part of this being done by Taiichi Ohno), he was responsible for documenting it and adding two words to the Japanese and English languages - Poka-Yoke (mistake-proofing) and single-minute exchange of dies (SMED), in which set up times are reduced from hours to minutes. He distinguished between "errors", which are inevitable, and "defects", which result when an error reaches a customer, the aim of Poka-Yoke being to stop errors becoming defects. Using Poka-Yoke in combination with source inspections creates Zero Quality Control, the ideal production system, eliminating the need for inspection of the end product or results, in which errors are examined before they become defects, the production system is stopped and immediate feedback is given so that the root causes of the problem may be identified (source inspection) and controls put in place to prevent them from occurring again (Poke-Yoke), with the addition of a checklist in recognition of the fact that humans can forget or make mistakes.

Dr. Walter Shewhart Walter Andrew Shewhart (pronounced like "shoe-heart", March 18, 1891 - March 11, 1967) was an American physicist, engineer and statistician, sometimes known as the father of statistical quality control. W. Edwards Deming said of him: As a statistician, he was, like so many of the rest of us, self-taught, on a good background of physics and mathematics. Early life and education Born in New Canton, Illinois to Anton and Esta Barney Shewhart, he attended the University of Illinois before being awarded his doctorate in physics from the University of California, Berkeley in 1917. Work on industrial quality Bell Telephone’s engineers had been working to improve the reliability of their transmission systems. Because amplifiers and other equipment had to be buried underground, there was a business need to reduce the frequency of failures and repairs. When Dr. Shewhart joined the Western Electric Company Inspection Engineering Department at the Hawthorne Works in 1918, industrial quality was limited to inspecting finished products and removing defective items. That all changed on May 16, 1924. Dr. Shewhart's boss, George D. Edwards, recalled: "Dr. Shewhart prepared a little memorandum only about a page in length. About a third of that page was given over to a simple diagram which we would all recognize today as a schematic control chart.
