Purpose: The purpose of this manuscript is twofold. First, this manuscript explores how dialogic evaluation (DE), as a participatory evaluation tool, develops inter-organizational learning (IOL). Second, based on empirical analysis, the work provides pragmatic insights to support practitioners in implementing a facilitative framework grounded in DE for the increased uptake of IOL. Design/methodology/approach: Two cases of multi-stakeholder partnerships in sport for development and peace (SDP) in Italy were analyzed and compared to explore whether and how the implementation of DE supported the development of IOL. Findings: In both cases, applying a three-phase DE process supported several IOL outcomes, such as common knowledge, new innovative solutions development and transfer of new acquisitions. Indeed, DE promoted three key IOL objectives: the emergence of latent relational dimensions and issues to bridge multiple levels; intra- and inter-redefinition and intersection of boundaries; awareness of relevance and usefulness of what was accomplished during the partnership. This paper also discusses some practical insights for DE methodology implementation to activate IOL. Originality/value: This research contributes to the understanding of an effective IOL by developing synergies from network interactions. Moreover, the researcher applied a novel methodology, DE, in IOL's research domain, focusing on a different context and setting such as SDP.
