The Constructive Cost Model (COCOMO) is a software project cost estimation technique created by Barry Boehm and published in his book “Software Engineering Economics.” Project Managers may use information based on these estimates to create their project schedules. The original model is often called COCOCO 81 and the revised version is called COCOMO II. The three levels of COCOMO 81 are Basic, Intermediate, and Detailed. The three levels of COCOMO II are Application Composition, Early Design, and Post-architecture. The different models represent additional predictors used in the estimation calculations. To experiment with how these estimates work, here is a simple COCOMO 81 calculator to calculate how many months of effort it will take to complete your software project: http://sunset.usc.edu/research/COCOMOII/cocomo81_pgm/cocomo81.html.
