"What do you think is the scope any one company is responsible for? Is there something about the quality of their output that they are not responsible for?" They are not responsible for the output of other companies. My question was whether you were speaking to what one company could do, or what was prevalent in the development ecosystem. It seems that you were speaking to the former. I certainly don't hold a position that there are no gains to be had focusing on the system. I do think it is most reasonable to say we don't know how to attain them in a way that acheives quality (or specifically lack of defects) at the level envisioned up-thread. The ways we do already know to attain that level of quality do impose substantial cost. (And for the record, I certainly agree that individual punishment of developers is unlikely to get us to any better place.)
