I am sorry,
What I ment was the Text of the Quallity policy.
What affects the Product quality is
directly the,
Drawings,
Control plans,
Work Instuctions,
Test Specifications,Etc.
The operators or the people concerned with the product quality must actually follow the above.
And if the concerned Dept.heads target the set objectives of the management (Which is derived from the policy) then the company by itself will have effective QMS and continually improve.
Hence I said the policy does not directly affect product quality.
