TL 9000 is the ISO 9000 based standard that was developed specifically for the telecommunications industry. TL 9000 was developed by an industry consortium called the QuEST forum, which consists of representatives from leading telecommunications service providers in the United States, Canada, and Britain. TL 9000 incorporates all of the elements of ISO 9001:2015, then adds requirements specific to the hardware, software and services segments within telecommunications. A further element of TL 9000 is the inclusion of “metrics,” a quantitative method of measuring cost and performance.
PJR was involved in the TL 9000 initiative from the beginning, being one of a select few registrars who participated in the formation of this important new standard by becoming a QuEST Forum Liaison Member. Being a Liaison Member allows PJR access to the most up-to-date information on TL 9000, which translates into the best service for PJR clients.
PJR is accredited by ANAB to register clients to TL 9000.
