Womack's Lean versus Ohno's TPS
As the blog post indicates, look to the comments for the well expressed discussion of the comparison of lean manufacturing and the Toyota Production System.
"Second, the Toyota Production System lives and belongs within Toyota. Any company emulating the TPS needs to study it deeply and then announce a never-ending commitment to developing the YOUR COMPANY business / operating / production System. Lean manufacturing is just a small part of it. Companies that do this are ridiculously successful."
