This deliverable presents the outcomes of the seven Mobilisation and Mutual Learning (MML) workshops conducted within the CATALISI project to support institutional transformation in European Higher Education Institutions (HEIs). The MMLs enabled mutual exchange, peer learning, reflection and co-creation among HEIs and selected external stakeholders, focusing on key intervention areas such as Open Science, Citizen Science, Research Culture, Sustainability in research, Reform of research assessment, Research careers and Public engagement. The report highlights the methodological approach, key results, lessons learned and recommendations for future implementation of mutual learning as an effective acceleration service for HEIs’ institutional transformation.
