You are back using the continuous approach.
The point is, you have followed the same book and the same information. You
have just selected a subset of all possible process areas listed in the staged approach
at Maturity Level 2. But you performed the same work and used the same book.
Only your selection of process areas and practices differed. That is the difference
between representations??”the extent of practices and the number of process areas
implemented in your organization. Although the wording was slightly different in
the previous version of the CMMI, the information contained in both representations
is now the same.
Because it is really the same book, we prefer to refer to them as approaches, and
not representations.
CMMI Representations n 55
Summary
Although the CMMI is promoted as having two very different representations, the
representations are really more similar than dissimilar. Instituting the practices and
subpractices is where the real benefits may be found. There are no new generic goals
for Maturity Levels 4 and 5 in the staged representation because the process areas
included in Maturity Level 4 and Level 5 include the basic tenets of those goals.
