This confuses me a bit. Any medical device, including computer systems
used for testing and data collection, plus equipment in the network is
rigidly controlled by FDA "validation" which is far more detailed,
rigid, and contains penalties for non conformance compared to ISO
As I said earlier, ISO can be an effective tool when properly
implemented and understood, but in the case of medical devices, I'd
expect FDA validation to be far more effective and restrictive.

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.

REPLY:
Exactly why it's a waste of time. Nobody cares about the "work process".
They care about the product.
A company can be in full compliance and still turn out junk.
Carefully documented junk.
ISO 9xxx is a perfect example of bureaucratic meddling with no benefit at
all.
Wise up, people.
