Purpose :
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 (1) of the three (3) models, which is the Basic Model.

  Introduction :
In his classic book on "Software Enginnering Econonics," Barry Boehm introduces a hierarchy of software estimation models bearing the name COCOMO, for COnstructive COst MOdel. Boehm's hierarchy of models takes the following form:

• Mode 1 : The basic COCOMO model computes software development effort (and cost) as a function of program size expressed in estimated lines of code (LOC).
• Model 2 : 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.
• Model 3 : 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.
