CMM :- A module or guideline ?for judging the maturity of the software processes of an organization and for identifying the key practices that are required to increase the maturity of these processes?, developed by the Software Engineer Institute (SEI). CMM is usually used, as above, to refer to CMM-SW, the CMM for software, though there are now also CMMs? for people, software acquisition and integration. Though SEI develops and promotes these Capability Maturity Models (CMM), the SEI itself does not certify the CMM-level or organization. 
 
CMMI ? See Capability Maturity Model CMM Level 1 Initial. -.No set processes- Processes used on an ad-hoc basis. Each project implemented in a manner that the project manager and team see fit. Software Management people centric and there is a dependence on ?Champion? Project Managers for project success.

Dear friend its CMMI not CMM1 
 
CMM as u described is absolutely correct. 
 
As u said there are different CMM's for diff processes, an effort has been made to integrate these CMM's for process improvement, these three CMM"s have been chosen due to their widespread adoption in software and system engg communities and also due to their diff approaches, Hence these three models SW-CMM, the SECM, and the IPD-CMM integrated into one is called CMMI( capability maturity model Integration)

CMM is mainly designed for software engineering. But CMMI can be used for other engineering streams.
