Which TWO of the following statements are TRUE about a model-based improvement approach?

A model-based improvement approach is characterized by the use of structured models such as GQM or TMMi® to guide improvement through levels and steps. The GQM model (Goal-Question-Metric) is a known example of a model-based approach. Such models typically break improvements into levels or steps, promoting maturity through defined phases.

→ TMMi® definesfivematurity levels, not four, making statement E incorrect.

→ Statement C is incorrect since model-based improvement can be applied both at project and organizational levels.

→ Statement B istruefor TPI NEXT®, not false, but it isnot selecteddue to the expected best fit being A and D, aligning with the general model characteristics used in test management.
