COCOMO suite methodology and evolution

An overview of the models in the COCOMO suite that includes extensions and independent models, and describes the underlying methodologies and the logic behind the models and how they can be used together to support larger software system estimation needs, is presented. The models in this suite provide specialized set of estimates that address specific aspects of development effort for software-intensive systems. The models also provide a set of tools that enable more comprehensive cost estimates. The developments done on multiple COCOMO models in parallel for cost estimates that cover a broader scope that exceeds the boundaries of traditional software development are discussed.
