> One of the fascinating things about lean manufacturing is that few companies outside of Toyota (let alone manufacturing) have ever successfully gone lean. Projects like NUMMI were a failure. Is that really true? I'm asking not debating, as I may have selection bias in how I observe Lean Manufacturing through the lens of small to mid size companies with active public relations via the internet. > I think the key that makes process improvement work in manufacturing is that the production line is continuous, and the measuring of outcomes is independent. Car quality, customer satisfaction, units produced, mistakes, etc. I think this makes a lot of sense. The products in software development are a lot more nebulous.
