My first shoot from the hip response upon reading this was "this is more of a "Mission Statement" or a "Core Values" statement that would be posted in the lobby with pretty calligraphy, or as a byline on your webpage." Upon reading the other posts from the Covers, I have some additional thoughts.
1) You mentioned that you did not think any customer has ever seen it or asked for it. If they did, would you comply quickly? And if you did, would they see it is a marketing pitch or as a quality policy?
2) You mentioned that you do not have the cojones to show this to your boss. Why not? If you are the Quality Manager, is it not your responsibility to advise him on Quality functions and activity?
3) As I read the Quality Policy, it was evident that the last line was added to meet a requirement and not as an integral part of the company policy. Most team members in a company barely know the company has a "Mission Statement" let alone work by it. Is this the case where you are?
4) I agree with Wes wholeheartedly. As a business pitch, it is not very good. You are going to listen to me, WOW thanks. As a polysylballic statement, a prep school kid could do better. As for the employees, what about me?
5) I do not think you will garner a Non-conformance for the way it is currently written, however it could be revised to more accurately reflect what your company can and will do in regards to Quality, Business Acumen, and Sustainability.
Just some thoughts.....
