TMMi MODEL

The TMMi Foundation has created the Test Maturity Model integration (TMMi), a detailed model for test process improvement. Testing as defined in the TMMi is applied in its broadest sense to encompass all software product quality related activities. TMMi addresses all test levels (including static testing) and aspects of structured testing. TMMi is intended to be life cycle independent. (The TMMi Model is among others also available in French, Spanish, Portuguese, Italian and Chinese.) Below also the documents that describe how to apply and use TMMi in an Agile, DevOps and AI context.

TMMi PROFESSIONAL

The TMMi Professional qualification is appropriate for anyone who wants a basic understanding of the TMMi model. The TMMi Professional document describes the learning objectives and other aspects for a TMMi model training, including how to apply TMMi in an Agile context. Training providers can develop a recognized TMMi Professional training based on this document. TMMi Professional qualification is also a pre-requisite of becoming a Certified TMMi test process improver. Certified TMMi test process improver supports career path development and creates visibility for those involved in TMMi based test process improvement.

ASSESSMENTS

The TMMi Assessment Method Application Requirements (TAMAR) document (see below) lists the requirements for a TMMi assessment process. Based on TAMAR organizations can develop their TMMi assessment process and have it accredited, or license the TMMi Asssessment Method (TAM) from the TMMi Foundation. The TMMi Assessor course syllabus describes the learning objectives for a TMMi Assessor training. Training providers can develop a recognized TMMi Assessor training based on this document. Check out the recognized TMMi Assessor training providers.

There are also specific criteria for TMMi (lead) assessors. Upon re-accreditation, assessors that do not meet the required number of experience hours can take a re-accreditation exam. A sample exam paper is provided by the TMMi Foundation.

BOOKS

Regarding test process improvement and specifically TMMi, Erik has published a number of papers, including the results of the first TMMi benchmark. The following TMMi books have been published:

The Little TMMi – Objective-Driven Test Process Improvement (also available in Dutch, Spanish and Chinese)
Test Maturity Model integration – Guidelines for Test Process Improvement (also available in Chinese)

Also of interest to the TMMi audience is the ISTQB expert level book:
