COCOMO Calculation process This paper summarizes several classes of software cost estimation models and techniques: parametric models, expertise‐based techniques, learning‐oriented techniques, dynamics‐based models, regression‐based models, and composite‐Bayesian techniques for integrating expertise‐based and regression‐based models. e. The overall cost estimate is a result calculated by examining the optimistic, pessimistic, and most likely scenario Decomposition techniques take a divide and conquer approach.
