In the civic technology ecosystem, creating spaces and pathways for government practitioners and teams to connect and learn from one another is critical as we seek to address ongoing challenges in the design and delivery of government services, attract talent to public service, and retain people with the knowledge, skills, and abilities in government roles. In this TICTeC 2024 presentation, Kelly Henderson and Michaela Caudill (Beeck Center for Social Impact and Innovation at Georgetown University) share real-world lessons about cultivating communities of practice and building out programing and structures that facilitate the sharing of knowledge, artefacts, and ideas. These communities provide spaces that meaningfully inform government practitioners and teams in designing and delivering government services.
