Effective local participatory governance depends on government responsiveness. Drawing insights from empirical research in a large South African city, we show how inadequate integration of institutional platforms for community participation into the wider participatory system undermines this capacity. While much of the participatory governance literature considers tools, norms and the experiences of citizens, we explore how officials, structures and platforms within the city interact. We apply a systems lens to understand the municipal capacity to engage and respond to citizens and communities. Our analysis demonstrates that officials navigate an institutional system experiencing disconnected municipal structures, engagement practices and platforms. We theorise the government capacity to engage in terms of the personalisation, co‐creation and institutionalisation of responsiveness. This capacity to engage thus requires a systemic capability that acknowledges complexity and nurtures collective learning alongside institutional design strategies that seek to address potential disconnects.
