Actually calculating - understanding - cost of downtime, and what variations on
that exist over time, are keys to reliability engineering.
But if you plan to cover X failure scenarios and only cover X/2 failure
scenarios due to implementation glitches you goofed.
The right answer may be "relax and accept the downtime" and it may be "spend
$10 million dollars to avoid most of these". If you haven't thought it through
and quantified, do so...
