Talk:Kaizen

From Wikipedia, the free encyclopedia

Another take on "kaizen" — http://www.fredharriman.com/services/glossary/kaizen.html

kaizen's literal meaning is improvement. Kaizen in term of TQC might means continuous improvement. FWBOarticle

How is this an encyclopedia article? This should be moved to Wictionary.

Despite the dictionary style of some sections, Kaizen is not just a word, it's an important part of the work and maybe the culture of many people in many places.

I added a brief discussion of 5S just to get something in there, but it definitely requires a lot more meat. There's at least one good description under a CC license but I think it's not compatible with the Wikipedia settings for CC. So anything anyone can add is most welcome. -- Kyle Maxwell 2005-07-06

[edit] Cost Cutting

a method of (industrial) cost cutting

Kaizen is no more about "cost cutting", than Rolex wrist watches are about "time keeping".

It had more content before... Where did it go... I miss it... :)

Reducing waste and increasing efficiencies is cost cutting and a cost cutting that effectively improves quality. If we increase outs, improve quality and improve ct by reducing reworks or becoming more efficeint, it is an immediate cost savings.

[edit] perpetual improvement

Kaizen means perpetual improvement - for the good of mankind. Perpetual refinement with benevolence. Every solution is viewed as a temporary solution, until we see how and where further improvements can be made. Increasing profits beyond a reasonable amount is not kaizen, it is greed.

[edit] 5S as a Philosophy

5S is a Philosophy and a way of organizing and managing the workspace. Hiroyuki Hirano wrote an entire book about 5S called 5 Pillars of the Visual Workplace: The Sourcebook for 5S Implementation. While the article in it's current form is a definition it could be expaned upon to a great degree.

5S is customarily implimented in connection with a Kaizen, lean manufacturing, or continuous improvement program. However, 5S can be a stand-alone program and handled completely seperate of a continuous improvement, or kaizen, activity. Similarly, some organizations do not address 5S as part of their kaizen activity. Therefore, since 5S is not immutably linked to kaizen, it should remain as an independent article.

I agree that 5S should be separate. Kaizen and 5S are both processes and philosophies. However, while you can apply kaizen to all 5S, you cannot apply 5S to all kaizen. When I want to read more about 5S, I don't necessarily want to wade through pages of kaizen discussion. Ehusman 21:56, 9 December 2005 (UTC)

[edit] Translation

I have combined several statements into one, but does anyone with any **authority** know the real translation for "kai" and "zen"? In other words, someone fluent in both Japanese and English. I have read many books on the subject, but that doesn't mean that those authors are correct! Ehusman 21:53, 4 February 2006 (UTC)

[Reply] I'll give it a try, not claiming any **authority**, since this two words has similar meaning in Japanese as well as Chinese. I'm Chinese. "Kai (or Gai in Chinese pronunciation)" means "to change". In a simple way, "zen (shan)" means "good", as good vs. evil. But "zen" has a deeper meaning than just good/bad, or true/false, which is a little hard to translate. Combined, "kaizen" means "change for the good or for the benefit" of some purpose, or commonly interpreted in Lean as "continuous improvement" for the benefit of a company, organization, or one self.

[edit] kaizen is japanese ....

could you please add the japanese names and/or history behind kaizen? kaizen seems to be a japanese word, and a japanese principle which seems to be very old. it would be very astonishing if this was an invention by taylor, bunkher, and shewart.

kaizen is one of the cornerstones of tps, like jit is. and for tps taylor&al seemed to have an influence. but for kaizen i'm very doubtful.

Maazaki Isai says in Kaizen: The Key to Japan's Competitive Success, "It is well known that the initial concepts of statistical quality control and its managerial implications were brought to Japan by such pioneers as Deming and Juran in the postwar years. Less well known is the fact that the suggestion system was brought to Japan about the same time by TWI (Training Within Industries [sic]) and the U. S. Air Force. In addition, many Japanese executives who visited the United States right after the war learned about the suggestion system and started it at their companies."

In the intro to Dinero's Training Within Industry: The Foundation of Lean, John Shook writes about a time when he was working for Toyota when he "protested to my Japanese colleague, declaring that the program as configured just wouldn't do and required radical revision before being unleashed on the NUMMI workforce." His colleague, Toyota Master Trainer Iaso Kato, "stormed out and fetched from a back room file a yellowed, dog-eared, coffee-stained copy of the English-language original training manual, just as he had received it .... To my absolute amazement, the program that Toyota was going to great expense (including retranslating from Japanese to English) to "transfer" to NUMMI was exactly what the Americans had taught the Japanese decades earlier. Of course, it was JI, the Job Instruction module of TWI. Toyota still used it in 1984 and continues to use it today ...."

You could also check out the Training Within Industry page and take the link to Huntzinger's article, "The Roots of Lean; Training Within Industry: The Origin of Kaizen".

The Japanese certainly employed the methods with much more vigor than American industry. We see improvements in quality control by such people as Ishikawa, but as Shook's experience at Toyota makes clear, the basics of kaizen were largely in place by the end of WWII. TWI was emphatic about not changing the training program without substantial examination of the proposed change, so it isn't surprising that the program survived intact at Toyota. Ohno does not appear on the list of Deming Prize winners for individuals, and the contributions of people like Akao, Kaoru Ishikawa, Genichi Taguchi were mostly in statistical application, root cause analysis, and other ideas related to kaizen, but didn't do much to change the daily practice of kaizen itself. As to how it could have largely disappeared in the US while it flourished in Japan, I think Waddell & Bodek's Rebirth of American Industry gives some clues: basically, after the war, American manufacturers were the only world class manufacturers left standing, and they all abandoned Ford's methods (admired by both Toyoda and Ohno) and adopted the flawed Sloan system.

Strange but true. Ehusman 14:40, 28 May 2006 (UTC)

this might be very true. but there is no taylor, bunker, shewart in this history. but they had influence on tps via jit. --ThurnerRupert 10:11, 11 June 2006 (UTC)

apart from the fact i think your short explanation above is much more worth to be put into kaizen, tps, or lean production than the information which is currently there :)

--ThurnerRupert 10:49, 11 June 2006 (UTC)

Shewhart's main contribution was in statistical process control. Taylor had nothing to do with JIT; that evolved mostly from Ohno and somewhat from Ford (who had already gone into mass production when Taylor was first getting published). Don't know about Bunker - do you mean the Gilbreth's (Frank and Lillian)? They, like Taylor, did time and motion studies, but, also like Taylor, they believed that workers should work and managers should think, the opposite of the Kaizen ethic. Remember Kanosuke Matsushita's famous claim that "Yes, we will win and you will lose. For you are not able to rid your minds of the obsolete Taylorism that we never had." He knew that Taylorism <> kaizen. Ehusman 00:15, 2 August 2006 (UTC)

Does this link provide any relevant information on continuous improvement/kaizen? Leaders100 11:35, 13 June 2006 (UTC)

[edit] Wants criticism

where's the criticism section ? surely it's not all good (case in point, take word is thrown around like it's candy by the corporate droids where I work surely it can be all that good) From 216.113.99.17 on 12 June 2006

[edit] Doesn't like link to gaming Kaizen

Why put "For Kaizen, the fantasy currency used in Priston Brazil, see Kaizen Games." at the top of this article? I send people to this page so they can read about Kaizen, and the first line is BS which turns people off. From Jsong123 on 18 July 2006.

It's not BS, it's proper wiki practice and better than a disambiguation page Ehusman 23:58, 1 August 2006 (UTC)
