Helps You With

The TL 9000 standard was developed by and specifically for the communications industry to drive consistency in expectations, increased performance and continual improvement.

Please note: The TL 9000 standard is undergoing a major revision in keeping with the changes being made to the ISO 9001 standard - click here to keep up to date.

WHAT IS TL 9000?

The industry group QuEST Forum, a unique partnership of communications service providers, suppliers, and industry liaisons, has defined TL 9000 in two handbooks: Management System Requirements and Management System Measurements.

Organizations may register to any combination of the three options—hardware, software, and service—within the requirements, tailored to the nature of their business. The standard requires detailed measurements that must be tracked, providing critical data of the organization’s performance and allowing benchmarking via the QuEST registration measurement system.

Even if your customers have not yet mandated TL 9000 registration, can your organization afford to be without this information?

“You both were excellent on the audits and your bedside manner with the folks you interviewed. I appreciate working with pro's... Sanmina P20 will be much better due to your efforts.” Wayne Simmons, Sanmina Quality Manager

“I realized at the end of the day that we didn't thank you (or Bill, for that matter) sufficiently for facilitating the session. I really appreciate that you did it, especially on short notice. From the time I was in the room it seemed like you were pretty effective at getting people going. Your thoughts on future discussion topics and methods will be valuable to OSWG Leadership.” Karen Rawson, Vice President at The DESARA Group 

"Thank you for conducting our Montreal surveillance audit last Thursday and Friday. As always, we appreciate your thoroughness and your deep knowledge of the TL 9000 standard." Tom Liu, Director of Delivery Programs at BroadSoft, Inc.
