Zeev,
Re.:"...perfection does not exist (by definition)..."
My question was in reference to "...perfect quality means zero yields..."
Changing "...perfect..." to "...perfection..." in your reply twists the whole discussion, intentional or unintentional. I am not concerned with "...perfection...", an abstract concept, not known to attract the attention of cost-conscious manufacturing engineers.
Yield optimization CAN NOT be constrained (mathematically or physically) by the number of steps involved, whether it involves 20 steps or 200 steps to manufacture a product or provide a service to customers.
In TOTAL QUALITY MANAGEMENT as applies to commercial manufacturing or service, engineers and management strive for "perfect" quality, not "perfection". There is a big difference. Quality does not stop at 98%, or 99% or 99.9999%. Even at a defect rate of 0.0001%,several hundred flights will crash, several thousand babies will die during birth, etc. etc.
Instead of continuing a discussion of "semantics" or trying to run a manufacturing floor operations from my computer keyboard, I'll end my discussion and remind longs a statement made by Lev in the last CC:
"VLNC will fail, not because of technology, not because of lack of capital, but because of poor product quality."
