This statement confuses me. It is an inherent phenomenon of engineering
that either you 1) ensure that worst-case parts will still work
together, or 2) some combinations of parts will fail even though each is
within specifications. The latter is simply not a tolerable situation
to me. It's simple math, if you want 10,000,000 trouble free
installations, then you're going to have to ensure that the
one-in-a-million combination of worst-case devices still works.
Is there really *any* other way to go about this?
