The TL9000 Telecommunication Quality Management Standard
TL 9000 was developed for the telecommunications industry, including carriers and all other product and service providers in this industry.
The author of TL 9000 is the QuEST Forum (Quality Excellence for Suppliers of Telecommunications). The QuEST forum has a global reach. The content of TL 9000 is chosen by its members, who are made up of representatives from the telecommunications industry.
As with other standards, such as ISO 9001 Quality Management Systems, ISO 14001 Environmental Management Systems, and ISO 45001 Occupational Health & Management Systems (OHSMS), the requirements of each standard are designed to integrate well with each other. This means that dual certification with another management system standard is simplified.
Why Achieve the TL 9000 Certification for Your Business?
TL 9000 is based on ISO 9001. It adds several aspects that are specific to telecommunications. Most of them are relevant to all suppliers, but some are specific to hardware, software, or services, or a combination of either.
TL 9000 is truly unique. As part of the requirements for certification, applicants also need to submit performance data to a database that is managed in Texas. The submission of performance data helps to push and promote continual improvement for the whole of the telecommunications industry. So far, statistics show that organizations with TL 9000 certification are indeed improving on several important performance criteria.
