TMMi® (Test Maturity Model Integration)has five maturity levels: Initial, Managed, Defined, Measured, and Optimization.
Other models, likeTPI® NEXT, focus on key areas but do not use a maturity-level framework.
CMMi® (Capability Maturity Model Integration)applies broadly to process improvement but is not specific to testing.
GQM (Goal-Question-Metric)is a measurement approach, not a maturity model.
Evaluation of Options:
A (TMMi®)is correct as it directly incorporates a five-level maturity framework for test process improvement.
Other options are not aligned with the question context.
References and Syllabus Alignment:
TMMi is referenced in the ISTQB syllabus under "Improving the Test Process" (TM-1.5.1) as a standard for maturity models.
