The COCOMO model was designed by B. Boehm and is thouroughly discussed
in his book "Software Engineering Economics".

The model has three levels of detail: Basic, Intermediate, and Advanced.

The Basic model is just that, basic.  	It has formulas for calculating,
based on the number of lines of deliverable source code, the number
of programmer-months required to develop the system.  Using the calculated
PMs the development time may be calculated. Finally by using the # of PMs
and the time required you can caculate the number of programmers needed
to complete the job.   

The Intermediate takes more variables into consideration such as tools
available, programmer experience, etc. The advanced model goes even
further.

Within each level of detail jobs are categorized in three ways: Organic,
Semi-detached and embedded. Each model has its own set of equations
for calculating the above info.  These modes are determined by the
compexity of the job.
