A Lean Sigma Book Says You Need Six Sigma to Address Defects

A book on Lean Six Sigma for healthcare talks about the eight types of waste. So far, so good.

Until the author talks about the "waste of defects" and claims that Lean addresses everything BUT defects and that you need Six Sigma to address defects.

That's hogwash.

From the book.

He talks about right sizing machines and reducing changeovers... those are core Lean concepts.
