Working through communities of practice has never been more encouraged in organisations than it is now. Better gathering, sharing and using of data, information and knowledge in public organisations such as the European Commission are essential to deliver integrated policy work and overcome silo mentalities. This is highlighted explicitly in European Commission President von der Leyen’s work guidelines stipulating transparency and the ambition to become a digitally transformed, user-focused and data-driven administration. Communities of practice are an excellent instrument for fostering collaboration among internal and external stakeholders: they can bring groups with different knowledge perspectives together and can strengthen their capacity to work and learn creatively together. Thus, communities of practice harness the collective intelligence in organisations and help improve performance.
