This article presents a social learning perspective as a means to analyze and facilitate collective decision making and action in managed resource systems such as platforms. First, the social learning perspective is developed in terms of a normative and analytical framework. The normative framework entails three value principles, namely, systems thinking, experimentation, and communicative rationality. The analytical framework is built up around the following questions: who learns, what is learned, why it is learned, and how. Next, this perspective is used to analyze two managed resource systems: Fishery management in Lake Aheme, Benin and water resources management in Gelderland, The Netherlands. To assess platform performance in resource use negotiation, emerging lessons from the case studies are combined with propositions concerning membership of platforms, accessibility of platform meetings, skills and relations of platform members, realization of platforms, and third party facilitation of platform activities.
