Software Configuration Management (SCM) is a process of controlling changes made to software work products. The Capability Maturity Model (CMM) defines the SCM as a key process area that provides detailed practices of controlling and managing the software work products. Unfortunately, the CMM specifies what would be expected in a software process, regardless of how the process is implemented. This research proposes a SCM workflow model that identifies sequences of practices that CMM organizations can follow to achieve the SCM key process area. Furthermore, a SCM Activities Supporting system is designed and developed to accomplish the defined SCM practices.
