"That seems to remove the requirement to control a number of areas like the cost of poor quality."
1- Cost of poor quality - 126.96.36.199
"The only area that I can find to call out any specifics is in GM's specific requirements from April 1999. "
2- Check first at WWW.iaob.org
"So how do I relate the old requirements into the new ones? Which are the "real" requirements? I can see the 6-8 "procedures" for a level 1 document. How about the number for level 2?"
3- There is no longer a tier/level 1 or 2 with the ISO/TS. There is only a quality manual.
There are only seven procedures required by the specification. You may have others, that's your choice. ISO/TS requires that you define your processes, again that's up to you ; flow charts, tables, etc.
