Telecommunications - TL9000
- TL 9000, released in 1999 and revised in 2001 to align with ISO 9001:2000, is the telecommunications industry derivative of ISO 9001. This standard harmonizes telecommunications quality management system (QMS) requirements for the design, development, production, delivery, installation and maintenance of hardware, software products, and services. Conformance to TL 9000 decreases time to market and improves the total cost of ownership throughout the supply chain.
- TL 9000’s structure contains five levels of QMS requirements and measurements. They are ISO 9001:2000; common telecommunications industry quality system requirements (QSRs); hardware, software and services specific QSRs; common telecommunications industry measurements; and hardware, software and services specific quality system measurements.
- TL 9000’s telecommunications sector-specific QSRs are divided into six categories and marked accordingly: common (C), hardware (H), software (S), services (V), hardware and software (HS), and hardware and services (HV). There are no services and software (VS) elements. A supplier is only required to implement the additional elements that fit its scope of operations. Only a hardware and software company that offers a service must implement all sector-specific requirements.
- TL 9000 breaks ground by establishing cost and performance based measurements that measure the reliability and quality performance of hardware, software and services. These performance measurement tools are important from the customer’s point of view and include hardware return rates, system outages, number of problem reports, software update quality, on-time delivery, invoice accuracy, and the efficiency and level of success of the supplier’s business processes and activities.
- TL 9000 registration may encompass an entire company, an organizational unit, a combination of units, several facilities, an individual facility, or a limited and defined product line. The registration scope may be for hardware, software, services or any combination thereof.
- The Quality Excellence for Suppliers of Telecommunications (QuEST) Forum is a unique partnership of telecommunications suppliers and service providers. It was founded by Bell Atlantic, BellSouth, Pacific Bell and Southwestern Bell and now has more than 110 members.
