Quality Principles 

---

Meet the Requirements
Establish and measure the customer's Critical to Quality (CTQ) characteristics. 

Strive for Error-Free Work
Establish and measure performance standards based on Six Sigma: 99.9997 percent or 3.4 defects per million. 

Design in Quality
Build quality into products and processes at the start, or manage by prevention. 

Measure and Improve Performance
Prioritize corrective action, measure progress and improve performance based on the cost of quality. Integrated Quality Management Systems ensure that product and service quality are more than compliant with the latest customer-recognized standards.  Exceptional performances of products in service over an extended period of time have proven that Corning Cable Systems Quality Management Systems are consistently effective.
