Thank you. TS and ISO audit has become a stressful experience because, the audits seems to make their own rules. They do not like our documentation and it turns out to be a negotiation experience.
So how far have we come? This (and examples from the Cove and my own experience) indicate the system is just as bad / corrupt as the days of the CBs managing the process themselves and even the days of 2nd party audits by the OEM's SQA engineers.
The 'boardroom' auditor is alive and well

It never ceases to amaze me how many bad apples there are out there and how anyone can have so little respect for their profession and themselves to be seen in this light.

BTW - rant over - you are 100% right that the controls don't have to be in the flow diagram. The automotive industry above most is renowned for documenting process controls - think process flow diagrams, FMEA, control plan from the supporting manuals for TS.
