The independence and authority for personnel performing work affecting quality is part of the corporate culture. As for the means to "demonstrate" it to an external party, it could be as simple as having a 1-sentence statement in the quality policy to the effect of something along the lines of: "...irrespective of any employee's primary job, everybody in the organization is empowered to report quality concerns and take appropriate actions to prevent nonconforming products from further processing or shipment. Quality must never succumb to other priorities..."Looking for some guidance on the requirement for independence within clause 5.5.1
Good luck.
