The purpose of this site is to help the end user making an estimate
using the COCOMO model(s). The end user will be able to use one

In his classic book on "Software Enginnering Econonics,"
Barry Boehm introduces a hierarchy of software estimation models bearing
COCOMO, for COnstructive
COst MOdel. Boehm's
hierarchy of models takes the following form:
The basic COCOMO model
computes software development effort (and cost) as a function of
program size expressed in estimated lines of code (LOC).
The Intermediate COCOMO
model computes software developement effort as a finction of program
size and set of "cost divers" that include subjective assessements of
product, hardware, personnel, and project attributees.
The Advanced COCOMO
model incorporates all characteristics of the intermediate version with
an assessment of the cost driver's impact on each step (analysis, design,
etc.) of the software engineering process.
