This statement is FALSE because TMMi does not focus only on higher test levels like system and acceptance testing. In fact, TMMi covers all test levels, including lower levels like unit and integration testing, as well as static testing (e.g., reviews and inspections).
TMMi is designed to address testing at all levels of the software lifecycle and goes beyond dynamic testing (e.g., system and acceptance) to include static testing techniques as well. The model is comprehensive and is intended to support testing in both systems and software engineering. Furthermore, TMMi addresses the four cornerstones of structured testing: lifecycle, techniques, infrastructure, and organization. These are essential to ensure a thorough and structured approach to improving test processes and aligning them with business goals.
TMMi Reference:
TMMi documentation clearly indicates that it covers all test levels including static testing (such as peer reviews) and dynamic testing across different stages of development.
It is lifecycle-independent and can support different models, such as Agile, DevOps, and traditional V-models.
