The Top 10 Titans of TPSBy Jon Miller | Post Date: February 8, 2009 11:31 PM | Comments: 8 Sean asked an interesting question:
This list of the top 10 titans of TPS is highly subjective and is organized in loose historical order, not in ranking by importance. It's a top 10 list, but we cranked it up to 11. And there are 12 people on the list, if you're counting...
Words of this titan: "It is not the employer who pays the wages. Employers only handle the money. It is the customer who pays the wages."
Words of the titan:
Words of this titan probably said, if not inspired:
Quote in reaction to the theft of designs for Toyoda looms: "They do not have the expertise gained from the failures it took to produce the original. We need not be concerned. We need only continue as always, making our improvements."
The unknown titan's quote:
Words of this titan to his executives:
Quote from Mr. Gilbreth:
Quote: "Costs do not exist to be calculated. Costs exist to be reduced."
Titan's quote: "It is not necessary to change, survival is not mandatory."
Quote: "Quality control begins and ends with education."
Three of many great quotes: "Knowledge has to be improved, challenged, and increased constantly, or it vanishes."
This is an interesting question and the response is very informative, especially about Wollard. I agree with the list of titans mentioned and would like to add another key influencer for consideration: Thomas Blanchard in 1822 rigged 14 machines at the Springfield Armory in the U.S. to progressively make rifle gun stocks with no manual labor. He might not be in the same category with all the above giants, but it was a milestone in the development of lean. There is a timeline called "Breakthrough Moments in Lean" from the Lean Enterprise Institute (Full disclosure, I work for LEI.) But if the group is intested, I can give the moderator a pdf to post for download. (Everyone will save $5.) I think people will find it interesting. It begins in the 1500s at the arsenal in Venice. Poster: Chet Marchwinski | Post Date: February 9, 2009 1:03 PM Hi Panu, I agree that Taguchi has certainly been very influential. Deming is more famous and benefits from being the "foreign" expert also. Hi Chet, Thanks for the introduction to Thomas Blanchard. It sounds like he is a pioneer in the man-machine separation aspect of jidoka. Here is the PDF on Breakthrough Moments in Lean has generously shared with our readers by the Lean Enterprise Institute: LeanTimeline08.pdf. It's also been featured on it's own blog post today. Charles R Allen's book We found a Allen's book The Instructor, the Man and the Job as a scanned file (215MB PDF) available for download.

Who all will be in your list? -Harish Poster: Harish | Post Date: February 9, 2009 5:45 PM Hi Harish, The list would be the same. Poster: Jon Miller | Post Date: February 9, 2009 6:44 PM Hello Jon, very good list. There would never be absolute consensus regarding THE top 10 of TPS, yet I would contend that Shigeo Shingo must be in the top 5. His book "A Study of the Toyota Production System" is one of the best book written on TPS. Shingo worked very closely with Ohno in developing small batch flow within Toyota. He introduced SMED and helped Ohno implement kanban. Therefore some may even say that TPS would be nothing without Shingo's contributions. Jon, I don't want to sound critical, because I have read many of your articles and found them to be top-rate; I just think Shingo deserves a lot more credit that he is generally given. Poster: Dane Bohnert | Post Date: February 22, 2009 9:40 AM Hi Dane, I do agree with you that Shigeo Shingo gave us a lot of insight into TPS through his books. There is a very different understanding of Shingo's role and contribution in the development of the TPS between people at Toyota and those of us who have read his books in English. I would refer you to two articles by Art Smalley, formerly of Toyota, on his investigations in this matter. I recommend visiting downloading an article titled A Brief Investigation into the Origins of the Toyota Production System. This is an excerpt from Shingo's Influence on TPS , Art Smalley's interview with Isao Kato who knew Taiichi Ohno and Shigeo Shingo well. Start excerpt: Art: So his biggest contribution was not in the area of set up reduction (SMED)? Mr. Kato: Actually no. There is a lot of historic misrepresentation and miscommunication of the facts regarding that topic. Toyota was already reducing set up time before he came to the company. Just using the simple eliminate, combine, rearrange, and simplify (ECRS) framework from our TWI Job Methods training course Toyota had already brought die change times down from four hours to one hour and 40 minutes for example without any outside help. Art: But didn’t he famously reduce a 1,000 ton changeover press from over four hours to under 3 minutes or some level in Toyota? Mr. Kato: Somehow this fact has continually been mistaken and misrepresented over the years in various books and articles. Mr. Shingo’s single minute die exchange accomplishments were all accomplished outside of Toyota in other companies on smaller machines. Toyota had been working on its own to reduce its longest change over time on it largest press and succeeded in reducing it from four hours to around one hour and 40 minutes. One day Mr. Ohno asked Mr. Shingo to look at this current changeover process and give us ideas on how to reduce it to under ten minutes. Mr. Shingo studied the problem and shared with us his distinction between internal and external work and the framework. It made sense but didn’t immediately solve any of the current problems. Art: So he didn’t actually invent or implement SMED at Toyota? Mr. Kato: He gave us some specific suggestions to work on and those ideas plus some others that a team was concurrently working on helped to reduce set up time from one hour and forty minutes it down to just about forty minutes. That was as far as they were able to reduce the time however during that particular workshop and it was his only real involvement in reducing changeover time at Toyota. Eventually several years later the engineers on their own with Mr. Ohno’s constant prodding were able to get the time under ten minutes but it was without Mr. Shingo’s direct help. He did provide some earlier advice however. Unfortunately this sequence of events has been misrepresented over the years somehow. End excerpt. So no disrespect whatsoever to Mr. Shingo but I didn't feel it was appropriate to include him in the top 10 with others who developed the foundational thought and application of TPS. Poster: Jon Miller | Post Date: February 22, 2009 10:15 AM Hi Jon, your points are good. I have read many of Art Smalley's articles, including the one you mentioned (I actually read it after my post above). Great info...my knowledge of Toyota history is trivial compared to Mr. Smalley's. I actually worked for Toyota in Supplier Development out of Princeton, and Shingo's book I mentioned was required reading in my group. From a technical perspective, Mr. Shingo was top-notch, but I probably over-estimated his contributions. Poster: Dane Bohnert | Post Date: August 20, 2009 3:17 PM |








I heard an opinion that it was actually Taguchi who was 'father' of Japanese quality, not Deming. As Taguchi's work was published before Deming first time set foot in Japan.
