In 1998, QuEST Forum (now TIA QuEST Forum) developed the TL 9000 Quality Management System to meet the supply chain quality requirements of the worldwide information and communication technologies (ICT) industry. Through TL 9000, it set out to achieve the following goals:

  • Establish and maintain a common set of ICT QMS requirements, which reduces the number of standards for the industry
  • Foster a system that protects the integrity and use of ICT hardware, software and services
  • Define effective cost and performance-based measurements to guide progress and evaluate the results of QMS implementation
  • Drive continual improvement and enhance customer relationships
  • Leverage the industry conformity assessment process

TL 9000: A Two-part Quality Management System
The TL 9000 standard is the ICT industry's unique extension to ISO 9001:2015 and includes supplemental requirements in the following areas:

  • Performance measurements based on reliability of product
  • Software development and life-cycle management
  • Requirements for specialized service functions such as installation and engineering
  • Requirements to address communications between customers and suppliers
  • Reporting of quality measurement data to a central repository

As a result, the TL 9000 is a two-part quality system with significant management and measurement components. In particular, TL 9000 certified organizations are required to comply with:

  • All requirements clauses of the International Standards ISO 9001:2015
  • ICT-specific requirements that apply to all registrations
  • ICT-specific requirements that apply to hardware, software and/or service registrations
  • ICT industry measurements that apply in all product categories
  • ICT industry measurements that apply in certain product categories specific to hardware, software and/or services

The TL 9000 Requirements Handbook and Measurements Handbook provide exhaustive information on both aspects of this quality management system.
