- I are confused'. The largest single factor in the COCOMO (different spelling?
- - no wonder) is the personnel and team capability. It seems that COCOMO agrees
- with you rather than disagrees. Is there something different about the
- calibrated databses that you have looked? COCOMO does nothing for you unless
- it is used for a while, calibrated, and improved.

- BTW, I agree with your point about application domains. Software must retain
- the real world in its requirements. What we do it real, and impacts people (
- and sometimes the ground!).
