TL9000:1998

What is TL9000 ?
TL9000 requirements were developed by the QuEST forum (The Quality Excellence for Suppliers of Telecommunications Leadership). The QuEST forum used ISO9000 as a baseline for the existing industry standards and practices in developing the TL9000.requirements. The development of sector-specific requirements for hardware, software and services quality system and metrics requirements is an essential part of TL9000.

Structure and Content of TL9000
TL9000 is based on the requirements of ISO9001, with supplementary requirements addressing the following principal areas:

reliability and associated costs,
software development and life-cycle management,
requirements for specialized service functions such as installation and engineering,
requirements to address the unique continuing communication between telecommunications service providers and suppliers.

TL9000 Model:

Benchmarking by QuEST & University of Texas at Dallas:
QuEST Forum establishes a central database for all TL9000-registered organizations to submit specific metrics data for benchmarking purposes. This is maintained by the University of Texas at Dallas, which is independent of the QuEST Forum, and is administered by the American Society for Quality.
