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...
