There are oranges, there are apples. What —on the face of the Earth— are you trying to do when asking “Which is better? Oranges or apples?”

A reasonable answer for such kind of questions could be just another question like: “Better for what?” and then trying to figure out what is the core interest behind such apparently illogical questions. Oftentimes, the hidden core interest ends up -once unveiled- a completely different concern with little relation to the original wording.

There is CMMI, for improvement of —whichever selected— process, there is agile mindset that encompasses a concrete development process. So you see, they are different matters and trying to compare each other is futile (CMMI/CMM are related as a whole/part relationship).

As Mark C. Paulk (CMM author) have said* CMM is a prescription of the “what” should an organization do and it is not concerned with any description of how really execute that prescription. An agile process in the trenches represents a description of how development goes on.
