This is the landing page for three cocomo software cost estimation models: The cocomo cost estimation model is used by thousands of software project managers, and is based on a study of hundreds of software projects. Boehm proposed cocomo (constructive cost estimation model) in 1981.cocomo is one of the most generally used software estimation models in the world.
