As the COSYSMO model transitions from the development phase into the adoption phase, industry stakeholders are beginning to embrace the model and integrate it into their existing measurement processes. To date, much of the guidance provided by the COSYSMO development team has been focused on the usage of the model. In the adoption phase, users need guidance on how to adopt the model as they work to convince management to invest resources in competition with other process improvement initiatives. This paper outlines a process which provides guidance on the piloting and institutionalization of COSYSMO designed to help scope the effort needed for successful adoption and implementation. The process has been developed as a result of interactions with over a dozen organizations that have participated in the industry calibration of the model and have begun to integrate the model into their internal processes. The knowledge obtained from working with these organizations is reflected in this process.
