Lesson plan

Testing Maturity Model

The Testing Maturity Model (TMM) was based on the Capability Maturity Model, and first produced by the Illinois Institute of Technology. Its aim to be used in a similar way to CMM, that is to provide a framework for assessing the maturity of the test processes in an organization, and so providing targets on improving maturity. The TMM has been since replaced by the Test Maturity Model integration and is now managed by the TMMI Foundation. To reflect modern systems engineering and align tightly with the newer CMMI framework, the model evolved into the Test Maturity Model integration (TMMi) under the stewardship of the TMMi Foundation. In June 2026, the foundation officially launched version 2.0 to fully adapt the framework for modern continuous delivery ecosystems, embedding Quality Engineering principles, Agile/DevOps methodologies, and validation guidelines for Artificial Intelligence (AI) into its structure. Each level from 2 upwards has a defined set of processes and goals, which lead to practices and sub-practices.
