To assure customer satisfaction, aerospace industry manufacturers must produce world class quality products at the lowest possible cost. AS9000 standardizes, to the greatest extent possible, the quality system requirements of the aerospace industry. Standardization of compliance requirements results in cost savings due to the elimination or reduction of unique requirements developed for each different customer. AS9000 Appendix 1, AS9000 Audit Summary and Supplier Profile Instructions, facilitates the standardization of this process.
