Even though more and more organizations are moving into a lean environment, there aren't that many great reference materials yet out there. If you go to your local bookstore - even the large ones in metropolitan cities - there are only handful of books on lean (in stock). Of course, you'll find a wider selection on Amazon, but lean materials are "not reaching the masses." On my recent trip to Japan, I was astonished to see so many books on lean and the Toyota Way at a small, local bookstore in Tokyo.
Maybe that's why they are so zealous about lean.....support materials and networks are abundant there. Should I get someone to start translating these books??
