good theme - don't let it get lost
There is a good theme in this thread. I hope we don't let it get lost. JSW is correct - of course there is a cultural component to 5S.
Companies make a big mistake if they try to "mimic" Japanese methods, blindly and without thought. However, there is value in the concepts, whether they are Lean, 5S, mistake-proofing, etc. The best way to adopt any method is to learn and understand it first. Synthesize it. Make it yours. Then implement the concepts, in English, and make them yours. Then they have depth, and aren't just a 2 dimensional flavor of the month.
Perhaps that is why it sometimes there is cynicism on this board. There are a lot of sincere quality professionals who don't get the support from their management to actually accomplish some of these things. That tends to wear you out after a while.
