This study addresses the concept of smart governance in the context of smart cities, with a focus on analyzing the phenomenon of smart collaboration. Relying on the existing collaboration and participation concepts in the smart city domain, an empirical analysis was undertaken of how ICT can promote collaborative governance and increase the participation and engagement in government. The multiple case studies focus on three cities in Brazil that run municipal operations centers in an effort to "become smarter": Rio de Janeiro, Porto Alegre, and Belo Horizonte. Interviews with directors, managers, and technicians shed light on the contribution that ICT makes in promoting an environment of collaboration in the government. The findings have revealed that ICT has an important role in supporting information sharing and integration between government agencies and external stakeholders, including citizens, especially in developing countries.
