Most smaller organizations
and less mature organizations have indicated that this is a good PA, but far
too diffi cult to implement at Level 2. So with the increased scope of the
model including the various disciplines (systems engineering, hardware engineering,
etc.), plus the additional PAs, the two models and the two levels are
dissimilar.
2. The process areas and practices for Levels 4 and 5 do not significantly raise
the bar, as higher maturity organizations helped devise this model.

Reports from earlier appraisals done by the Ministry of Defence in Australia
have specifically reported that the CMMI has made achieving Level 4
and 5 much more diffi cult. Whereas in the previous CMM for Software, the
recommendation was to ???keep it simple,??? now the implementation of these
areas requires much more training and quantitative measurement techniques
to be instituted in the organization. Responses heard at industry conferences
have also mentioned that the CMMI focuses too heavily on sophisticated
measurement techniques.
