This project explores Public Sector Innovation Labs (PSI Labs) in the Latin American context with a particular focus on designer’s contributions. PSI Labs provide a fantastic opportunity for governments to experiment and innovate how public services are delivered to citizens and improve public institutions’ operations. PSI Labs are becoming increasingly visible, but research has mainly focused on PSI Labs in Europe and North America. Moreover, research has also concentrated on PSI Labs as an institution but not on the people working in them. This thesis attempts to contribute to this growing body of research by studying the particularities of operating PSI Labs in Latin America and design/ers contributions in a space that, according to some proponents, can play an important role in addressing pressing social challenges. By engaging with designers and public servants from other disciplines through semi-structured interviews, this thesis presents insights and proposes future directions that could strengthen PSI Labs structures in Latin America and design contributions. Finally, research findings are synthesized in the form of a Giga map that includes the following themes: challenges, best practices, ideal conditions, expert design, learning opportunities for designers and other public servants, and qualities and expertise of people working in PSI Labs.
