I couldn't get this through my mailer back to Dave Prince.  Perhaps other
readers would be interested in the reply.

Subject: Query concerning COCOMO Estimating Model

Dave,
I saw your note on a local BB feed.  Barry Boehm's big contribution to the
COCOMO model was to fine tune it for Ada.  However, I have several sheets
of data about COCOMO from a recent Software Project Management Course I took
and would be happy to fax you copies (or mail as you prefer) of the general
information, including basic equations and cost multiplier factors.

I took the liberty of running a quick calculation through the model, without
assuming any cost factor effects( such as experience, complexity, software
team capability, and a number of machine specific items) i.e. I used 1.0.
FOr a 400K line program, the model indicates about 3,710 man-months of
effort are required, and an allowable schedule of 38 months, with the
corresponding average staffing level of 10+ people.  For a more accurate
set of numbers, you will need to plug in the various factors, which can
generate a range of -40% to +150%, depending on impact.

Also, class materials were extracted from a book titled "The Art of 
Software Cost Estimation", but I have no author or publication data.
I'm sure someone has put the system into a software module, but I can't
help you much there.  Let me know if you'd like the paper data.

Happy Holidays
