Impact of CMMI Based Software Process Maturity on COCOMO II's Effort Estimation

The software capability maturity model has become a popular model for enhancing software development processes with the goal of developing high-quality software within budget and schedule. The software cost estimation model, constructive cost model, in its last update (constructive cost model II) has a set of seventeen cost drivers and a set of five scale factors. Process maturity is one of the five scale factors and its ratings are based on software capability maturity model. This paper examines the effect of process maturity on software development effort by deriving a new set of constructive cost model II's PMAT rating values based on the most recent version of CMM, i.e., capability maturity model integration.
