Management commitment is highlighted as one of the critical success factors in the context of implementing and sustaining test process improvements. Within the TMMi framework, senior management support is crucial for ensuring that necessary resources, funding, and priority are allocated to the improvement initiatives. This commitment must be sustained throughout the process to overcome potential resistance and ensure that the improvements are institutionalised. Without strong management commitment, the efforts may lose momentum, and the improvement goals may not be achieved.

This factor is critical across several levels of TMMi, as seen in processes related to institutionalising the test process (such as defining organisational policies, resource allocation, and performance evaluation).

This statement is not true regarding a staged model. In a staged model, such as TMMi, organisations must follow a pre-defined path through maturity levels, and the process areas are organised in a fixed order that must be achieved sequentially. Each maturity level forms the foundation for the next, meaning that an organisation cannot achieve process areas at different capability levels independently, as is possible in a continuous model like CMMI. The staged model is designed to ensure that each process area is fully implemented and institutionalised before progressing to the next maturity level.

The process area Non-functional Testing at TMMi Level 3 focuses on performing a structured test execution process for non-functional attributes of the system. The specific goals for this process area include:

Perform a Non-functional Product Risk Assessment

Perform Non-functional Test Analysis and Design

Perform Non-functional Test Implementation

The creation of a specific non-functional test plan is not explicitly listed as a goal within this process area, although defining a non-functional test approach is addressed. Hence, "Establish a Non-functional Test Plan" (B) is not a specific goal of the Non-functional Testing process area​​.

For the Test Policy and Strategy process area, with a 40% achievement, the appropriate compliance rating is "Partly achieved". According to TMMi, a process area is rated as "partly achieved" when a portion of the practices has been implemented, but significant improvements are still needed​​​.
