Through the example of Ciudadela Nuevo Occidente, a large social housing district in Medellín, this article describes a process that primarily involves co-learning and micro-negotiations that help produce the cognitive alignment necessary to the management of services. The hypothesis put forward in this article is that the frictions caused by the residents' difficulties in adapting to the socioeconomic , cultural and cognitive frameworks of their new environment, imposed by urban modernisation running processes, engender forms of service co-production that ultimately strengthen the utility's capacity to extend and adapt its delivery model while enhancing the quality of services.
