Do the CMMI and the SW-CMM use (as a baseline) formal assessment initiatives other than SCAMPI or CBA IPI?
Of course! The CMMI or the SW-CMM can certainly constitute references of choice for anyone looking for good ideas to improve ways of working or to reflect on replacement solutions with the current practices which could suffer from certain gaps. One can find examples, improvement paths, ideas to confront intuitions, etc. Several more or less formal evaluation methods, other than SCAMPI or CBA IPI, use the CMMI or the SW-CMM as a baseline.
