Having worked on the design, development, verification, and validation 
of life-critical medical devices (cardiac defibrillators), I can 
categorically state that process matters.  A lot.  ISO-9xxx is not 
appropriate for most manufacturing but if your life hangs in the 
balance, you had better hope and pray that the manufacturers of whatever 
instrument is about to help you see another day take their process 
seriously.  People expressing the attitude that ISO-9xxx had "no benefit 
at all" were vigorously encouraged to find another line of work and 
quickly.  When the product use environment is both complex and 
high-risk, design and production processes are absolutely critical.
