TL9000 Measurement Handbook.

PrefacePrefaceThe Quality Excellence for Suppliers of Telecommunications Forum (QuEST Forum) was founded to foster continued improvements to the quality and reliability of telecommunications service. The founders took the critical initial step of establishing a common set of quality management system requirements and measurements by creating the TL 9000 Quality Management System Requirements Handbook and the TL 9000 Quality Management System Measurements Handbook. These handbooks are the result of a cooperative effort among members of the telecommunications industry. The work of the QuEST Forum yields benefits to customers, their subscribers, and their suppliers. Membership is composed of telecommunication Service Providers, Suppliers, and Liaisons. Members fund and participate in the QuEST Forum, have defined voting rights, and are expected to contribute to the work of the QuEST Forum. Members vote on adoption of the TL 9000 structure, content, administration, and other questions coming before the QuEST Forum. The QuEST Forum establishes and maintains a common set of quality management system requirements and measurements built on currently used industry standards including ISO 9001:2000. The requirements and measurements promote consistency and efficiency, reduce redundancy and improve customer satisfaction. They also enable suppliers to improve quality and reliability, reduce costs, and increase competitiveness.TL 9000 Quality Management System Measurements Handbook 3.0 iv
