The SoftWare Capability Maturity Model (SW-CMM) 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 (COCOMO), in its last update (COCOMO II) has a set of seventeen cost drivers and a set of five scale factors. Process MATurity (PMAT) is one of the five scale factors and its ratings are based on SW-CMM. This paper investigates the impact of process maturity on software development schedule (cycle time) by deriving a new set of COCOMO II's PMAT rating values based on the most recent version of CMM, i.e. Capability Maturity Model Integration (CMMI).
