Arno Penzias described it very simply at talks he gave ca. 1996. The cost
of quality is negative. Once you factor in negative cost of quality then
things start to make a lot of sense.

Of course, like everything else, you don't just say 'Me Ogg. Cost quality
negative. ' and assume that buying infinite quality will earn you money.
It's complicated. But quality, figured in as a negative cost, explains a
lot of things. Esp. in the computer biz.
