"What Quality can let you get away with".
They're not the ones who certify a legal document so I'd be very wary of knowing what they'll let you get away with, as, unless it's in writing, you'll be the one for the high jump if you're outside the company procedures / Part 145 / Part M etc.
Knowing you company procedures, how they affect you, what could happen if you go outside them, how to change them would be a starter, but most companies have found different ways to skin their cat as it depends on whether they have a MOE or CAME or CAMME.
