In order to have a competitive software industry, it is essential to adopt standards and reference models of software processes quality. However, despite the growing adoption of standards and models, the number of organizations that adopt these is a small portion of the total population of software organizations. This paper presents a tool to support the implementation of decision analysis and resolution process in adherence to CMMI-DEV model. This tool aims to assist software organizations in the implementation of the CMMI-DEV model. We expect that this tool be more easily adopted by software organizations because it is based on models and standards largely accepted. Furthermore, this tool adopts free technologies (non-proprietary) in order to reduce costs.
