As an auditor once said to me:
"I am simply a Judge - interpreting and applying the ISO - QS Laws at the company interface level.
As the facilitator directing development, integration and implementation it is your responsibility to be a Teacher, Student, Guide, Navigator, Director and Choreographer, and to serve as a Lawyer - representing your client company. It is specifically your responsibility to challenge disputed 'gray' area interpretations, to argue and justify your client company's interpretation(s) of, and compliance with, (how they meet the intent of) the Law (ISO 9001 and/or QS 9000).
It is the responsibility of your client company management to ensure understanding of, and compliance with, internal systems and documentation - from ISO 9001 (or QS 9000) and the company Quality Systems manual to individual work instructions. It is a specific, necessary responsibility of your client company management to provide leadership and to be involved in the continuing process.
You can appeal my findings and decisions if you wish. There IS an appeals process (system).
And use lots of flow & organizational charts, and don't forget lots of tables of contents, matrices and various supporting databases... And there will be a quiz.... A big, long, expensive quiz.... And smaller quizzes about every 6 months..."
Well, that's not exactly what the guy said, but it better describes the reality.
