Frederick Winslow Taylor (March 20, 1856 – March 21, 1915) is most well known for his work on time and motion studies and scientific management. While the facts and data aspect of his work is aligned with modern Lean, his theories of management diverged from Lean in one major way. Taylor was a believer that control should be maintained by management, and that workers should be relegated to executing the work in the way management Read more…
Bill Smith (1929-1993) is the little-known inventor of Six Sigma while working at Motorola. Reportedly, his early version of the problem-solving steps was “MAIC”, or measure, analyze, improve, control, with “Define” added later to make it the current version, “DMAIC”. As a result of Smith’s efforts, Motorola was the first recipient of the Malcom Baldrige Award.
John Shook is a Lean author, and currently (as of 2020) the chairman of the Lean Global Network and a senior advisor to the Lean Enterprise Institute. He co-wrote Learning to See, the book that is most responsible for introducing Western manufacturing to value stream mapping. He also has the claim to fame of being the first American to work at Toyota’s world headquarters.
Shigeo Shingo (January 8, 1909 – November 14, 1990) is one of the early pioneers of the Toyota Production System. He worked with Taiichi Ohno, though there is some question as to how instrumental he was in the development of this new way of thinking. The debate ranges from him being a co-developer, to being a consultant, to being a mere contributor. What is not in dispute is that he was brilliant and documented the Read more…
Walter Andrew Shewhart (March 18, 1891 – March 11, 1967) was an engineer, statistician, and physicist. He did a great deal of work in industrial quality with an emphasis on statistical process control. He is perhaps best known for his impact on the PDCA cycle. Deming reportedly adopted it from the earlier works of Shewhart. In Out of the Crisis, Deming refers to the Shewhart Cycle as, essentially, “Plan-Do-Observe-Study”. He adds in a Step 5 Read more…
Mike Rother is an author of several books, two of which are associated with the LEI (Lean Enterprise Institute) and received the Shingo Publication Award. Mike is also affiliated with the University of Michigan. His biggest contribution to the Lean community lies in his promotion of the concept of value stream mapping in his book, Learning to See.
Dr. Jeffrey K. Liker is one of the foremost experts on the Toyota Production System and is a prolific writer on the subject. His most famous work is The Toyota Way, but he has authored several additional books on related topics. Dr. Liker is a professor at the University of Michigan.
Dr. Joseph M. Juran (December 24, 1904 – February 28, 2008) is well known for his work in managing to produce better quality, specifically in post-World War II Japan. Because of the timing and his area of expertise, he is closely associated with Deming. Deming, however, emphasized statistics in his approach, whereas Juran was more management oriented. Dr. Juran founded the Juran Insitute in 1979, which is still in operation as “Juran” now, long after Read more…

Dr. Kaoru Ishikawa (July 13, 1915 – April 16, 1989) was a professor of engineering at the University of Tokyo. He is most widely known for his work in the field of quality. He is credited with propagating the concept of quality circles (Deming shares in recognition for the growth of quality circles), and the cause and effect diagram. His impact on the latter is so strong, that it is still often called the Ishikawa Read more…
