Abstract. 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.
Experience in Systems Engineering Cost EstimationThe motivation for this adoption process came from witnessing several organizations struggle with the adoption of credible tools as a result of organizational obstacles. Literature on the topic of technology and innovation adoption points to organizational factors as the main drivers of adoption. A study of technology adoption in the Brazilian medical equipment industry showed that organization factors are the largest contributors to the adoption of an innovation, specifically the presence or absence of leadership supporting the implementation (Zilber et al 2006). Similarly, a study sponsored by the Software Engineering Institute showed that social systems are the main enablers of innovation diffusion in software engineering organizations (Bayer and Melone 1989).The COSYSMO working group has had an influx of new members. These members lack the historical discussions and background that drove key decisions and assumptions in COSYSMO during its six year development. An organization looking at COSYSMO for the first time may have tacit knowledge of cost modelling in general but may struggle when adopting a new model like COSYSMO. Organizations are jumping on the bandwagon with little or no training and limited knowledge of parameter definition discussions in the absence of any substantial implementation guidance or lessons learned to leverage. In an attempt to help prevent COSYSMO from falling into the silver bullet trap (i.e., "We tried to use COSYSMO but it didn't work"), this paper is aimed at providing just that guidance. By following the systematic
