LOC estimates for Ada Command and Control projects

[tfsg!dennis@uunet.uu.net (Dennis Gibbs)]

We are trying to produce coding estimates for our project and we would
like to solicit input to get an  estimate for the number  of lines  of
code (LOC) per day per developer.

Our definition  of LOC per day  is code  that is  developed, debugged,
tested, and documented.

The project in question is a small Command and Control project with an
estimated total code size of 50,000 lines.  Our system is event driven
with heavy Man-Machine Interfaces (MMI).  We are using OpenWindows for
the MMI, on Sun Sparcstation 2's.  For the  purposes of  this estimate
we would like to assume our programmers have  average proficiency with
Ada (not Ada wizards, but not novices either).

Can anyone out  there involved in  an Ada Command and  Control project
tell us what a reasonable figure would be for LOC per day would be?

Of course we realize that these figures are not always meaningful.   I
remember another net contributor  comparing LOC/per day to the  number
pounds  of airplane  Boeing builds  in a day, which, of course, is not
very meaningful.  Nevertheless, we still need some examples from  some
real-world Command and  Control Projects to  help with  our estimates. 

Just to throw out a figure, our current  estimate is  around 20-25 LOC
per day on average, but other examples would help us determine if this
is a good or bad estimate.

Can anyone help us?  This is an urgent need, so if  you think  you can 
help please do!

Thanks,
