Which ONE of the following statements accurately describes the difference between the TPI Next and TMMi models?
TMMi is a staged test-process maturity model that treats management commitment as an explicit, important enabler of process improvement. TPI Next is a flexible, key-area-based improvement model rather than a staged maturity model; the models therefore differ in this emphasis. TMMi is also complementary to CMMI, not unrelated to it.
