The completion of the TMMi model in 2013 met the criteria originally set by the Board of TMMi Foundation:
The TMMi model provides a standard reference model applicable for all industries
The TMMi follows industry good practices with over many industry test and software quality models reviewed and considered, with the good elements combined to ensure a totally integrated model.
Using the TMMi one can identify risks, testing strengths and best practices
In addition the TMMi model and assessment framework has been created to support TMMi-based assessments.
Using TMMi will improve test effectiveness and efficiency
Case studies have shown clear benefits in using the TMMi model.
A programme of test process improvements can be run using TMMi
Through the measurement of (intermediate) results, TMMi will provide detailed guidance for improvements.
Provide public governance, measurement and certification
A full accreditation scheme is available for assessment service providers, allowing organization to be certified against the TMMi.
Have a detailed model for test process improvement that is also positioned as complementary to CMMI
TMMi is complementary to CMMi in that it follows the same maturity structure and goes into much more detail regarding software testing.
