Just playing devil's advocate here...
I had no idea what ISO was until I googled it today after reading this thread. It instantly reminded me of my line of work, in health care. There are mountains of accreditations, certificates, continuing education curricula, state regulations...etc...that are in place so the staff, and the facility can perform at the highest level possible. Guess what. The nurse taking care of you with all those fancy letters after the name on her badge can (and does) still kill you with the wrong medication all the time.
Just because something, or someone is certified doesn't guarantee the highest quality product, or service.
Having said that...it is pretty cool that SD has gone through the trouble of the certification process. It shows they mean business, and quality is a top priority.
yeah there is a lot of truth to this-- in real estate we call it alphabet name soup with so many different designations now people can have with minimal secondary education making them appear more qualified or superior than which they really are... sure sound fancy though!!
