what is the difference between CMM and CMMI?
Answer Posted / $
CMM is a reference model of matured practices in a specified
discipline for e.g. Systems Engineering CMM,
Software CMM, People CMM, Software Acquisition CMM etc. But
they were difficult to integrate as and when needed.
So the CMMi evolved as a more matured set of guidelines and
was built combining the best components of individual
Disciplines of CMM (Software CMM, People CMM etc). It can be
applied to product manufacturing, People management,
Software development etc
The Capability Maturity Model is a baseline of key practices
that should be implemented by any entity developing or
maintaining a product which is completely or partially
software. With the SW-CMM, the emphasis is on the software
practices.
Whereas with the CMMI, we can find both software and systems
practices. We can imagine that these models would be the
outcome of vast consultation of successful projects which
would then be documented in a model of what to do to carry
out projects with success and to improve continuously, and
recommended to the software and systems engineering community
