The Acting phase of a test improvement cycle focuses on executing the planned improvements. Key activities during this phase include creating solutions to address identified problems, planning actions to implement those solutions, and piloting solutions before full-scale deployment. These steps ensure that the improvements are well-defined, tested in a controlled environment, and refined before being fully implemented across the organisation.

The process area Advanced Reviews belongs to TMMi Level 4 (Measured). At this maturity level, the focus is on quantitatively measuring and managing product quality, and advanced review techniques are employed to integrate peer reviews (static testing) with dynamic testing. These advanced reviews play a key role in ensuring that product quality is assessed early in the lifecycle and that testing is driven by measurable goals.

With a 40% achievement in the Test Planning process area, the rating would be "Partly achieved." According to TMMi, a process area is rated "Partly achieved" when the percentage of achievement is between 15% and 50%. This indicates that some practices have been implemented, but significant improvement is still required to meet the full requirements of the process area.

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 References:

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​.
