Comparison with other standards

Below is an easy comparative table between TL 9000, IATF 16949 and CMMI® quality management systems


TL 9000

IATF 16949



The TL 9000 standard adds specific telecom requirements and measurements to generic ISO 9000 practices

The IATF 16949 standard adds specific automotive requirements to generic ISO 9000 practices

The CMMI® model describes generic best practices for creating systems in any domain


The TL 9000 standard contains specific and detailed requirements as related to telecom

IATF 16949 standard contains specific and detailed requirements as related to automotive industry

CMMI® requires that goals be met, expects that practices related to those goals are implemented, and provides suggestions for detailed implementation of the practices


TL 9000 has a very strong focus on well-defined post–deployment measurements. Measurements are reported on a monthly basis for benchmarking purposes

IATF 16949 requires the use of measurements tied to business objectives for the purpose of continual improvement. However, these measures are not defined by the standard, and there are no reporting requirements

CMMI® focuses primarily on pre-deployment best practices and in-process measurements

Business and/or
Manufacturing Focus

TL 9000 incorporates business needs as specific requirements for hardware, software and services development. Post-delivery focus is emphasized

IATF 16949 incorporates business needs with an emphasis on hardware development and manufacturing

CMMI® requires that all the process areas, goals, and practices be interpreted based on business needs of the organization, but at fairly generic levels

Role of Customer

TL 9000 defines specific customer inputs and involvement as stakeholders

Not specified

CMMI® expects the organization to identify and involve relevant stakeholders, but does not specify them
