If we take a less-than-good-enough-quality product and iteratively inspect and rework/repair each defect, we will produce a good-enough product. Intuition seems to suggest that this *should* work! Can't you polish a rough piece of metal until it shines? Heck, mythbusters proved you actually can polish a terd.
The manufacturing industry figured out a long time ago that you can't inspect in quailty. Your process has to produce a product-that-meets-customer-requirements, and if it doesn't you have to fix your process.
Oh, and the terd? It was shiny, but it still stank. And they don't last very long, anyhow.
