Comparison with other standards

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

	TL 9000	IATF 16949	CMMI
Description	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
Requirements	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
Measurements	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
