The RISCOSS project aimed to specify risk identification, management, and mitigation methods for open source software adoption. It developed a 3-layer framework using statistical, logic-based, and multi-criteria decision making techniques to assess risks at the software, community, and business levels. The framework was evaluated through a collaboration between the Fondazione Bruno Kessler and the Project Management Institute - Trento Chapter, where volunteers used the tool to evaluate predefined and real-world scenarios and provided feedback on its usefulness and usability.
