Nowadays, the use of Open Source Software (OSS) components has become a driver for the primary and secondary information technology (IT) sector, among other factors, by the openness and innovation benefits that can give to the organizations, regardless of its business model and activities' nature. Nevertheless, IT companies and organizations still face numerous difficulties and challenges when making the strategic move to OSS. OSS is aligned with new challenges, which mainly derive from the way OSS is produced and the culture and values of OSS communities. In fact, OSS adoption impacts far beyond technology, because it requires a change in the organizational culture and reshaping IT decision-makers mindset. Therefore, this research work proposes a framework to support OSS adopters (i.e., software-related organizations that develop software and/or offer services relate to software) to analyze and evaluate the impact of adopting OSS as part of their software products and/or services offered to their customers/users, mainly in terms of their software related activities.
