The history regarding Shigeo Shingo may not be correct. First, I'm not sure he was a Toyota "Chief Engineer". He appears to have been a consultant. Second, the article may give Dr Shingo too much credit for "inventing" SMED. See http://www.superfactory.com/articles/Smalley_Shingo_TPS_Kato.htm, an interview with someone who claims to have worked with Dr Shingo at Toyota. Jpgilman 03:51, 6 July 2007 (UTC)Reply

Think I agree with your comment about his not being "Chief Engineer" and actually being a consultant. Interesting link. He claims to have started his thinking in 1950's with distinction between internal and external setup. Facius (talk) 16:29, 22 November 2007 (UTC)Reply

Shigeo Shingo didn't co-invent TPS, nor SMED. ( http://www.twisummit.cn/downloads/2007/Smalley_Origins_and_Facts_Regarding_TPS.pdf , http://www.allaboutlean.com/smed-history/ ) — Preceding unsigned comment added by Impinxue (talk • contribs) 16:03, 19 February 2016 (UTC)Reply

Huh?

I find this article difficult to understand. The first sentence of the "History" section is particularly difficult - what is this "effective operating time" that is being caused by "the change-over"? What do either of these have to do with SMED? I think this article is trying to say that "any wasted time switching from one process to another should be reduced to a minimum". Is that correct? If so, say so. Maury Markowitz (talk) 19:00, 25 November 2009 (UTC)Reply

The reason why it doesn't make any sense is that most of the first paragraph was removed by a vandal two years ago, and nobody bothered to check the change history before they cleaned up what was left. I've restored the missing text. DES (talk) 11:50, 5 November 2010 (UTC)Reply

Definitely a mistake.

The "improvement" from 3 minutes to 180 seconds took 20 years :) History section: "Over time they reduced these changeover times from hours to fifteen minutes by the 1960s, three minutes by the 1970s and then just 180 seconds by 1990s." 31.48.19.231 (talk) 20:38, 5 September 2017 (UTC)Reply

It's 2024 and still no correction. 217.165.238.189 (talk) 11:29, 21 February 2024 (UTC)Reply
