Well, implicit in the phrase "I can't point to a single one" is a recognition that I simply may be ignorant. But hosts of American companies have tried to "do Lean," and they figure out some basics like batch sizes, queuing theory, etc., but never get far enough for it to really take, because they cannot reshape their culture and the mindset of their workforce (from top to bottom).
I just meant that it's odd to me to see Lean show up in a political discussion. For me, Lean is a subject I've been studying as a complete amateur for a few years, and I've never observed it come up in any political discussion. At any rate, I am aware of a fairly substantial undertaking starting in the 90s to bring Lean management to our private health industry, but I've been reading some of Jim Womack's literature on their efforts to improve many industries, including health care... and he seems to paint a rather grim portrayal of actual real world success here in the States (and elsewhere). One of my favorite quotes of his goes something like this: "everyone knows the words to the new song, but few can carry the tune."
I've got a strong appreciation for the subject, I suppose my impulse was sparked from a feeling of, "hey, don't throw a baby out with the bathwater." Lean principles would help this country quite a bit. But the circumstances that allowed it to emerge at Toyota in the 50s would be considered toxic (and downright "socialistic") here.
