I spent most of my career, shipping finished product, which, in many cases, probably could have benefitted from an MVP-like "tuning phase," but we called that "beta." I think MVP generates more useful feedback, but I really don't like thinking of an MVP as "shipping software."

I also worked for hardware companies, where shipping stuff had some pretty serious stakes, and learned how to make sure we got it as good as possible, before getting it out the door.

I like the idea of evolutionary design, and "tuning," but I think it's a bad idea (for me) to deliberately ship bad software as an end-product.

(Also, MVP, by definition, generates lots of trouble tickets. I am allergic to trouble tickets. It's totally a personal thing, but I live by it).
