Networked Collaborative Action era
John Kania and Mark Kramer popularized the collective impact framework in 2011, detailing backbone organizations and shared measurement as the coordinating infrastructure for cross-sector, networked action. Hahrie Han's work on networked organizing explains how social networks, digital mediation, and diffusion-informed mobilization scale participation and cross-issue collaboration within learning networks. Marshall Ganz's scholarship on public narrative and field organizing illuminates how locally rooted campaigns are shaped, resourced, and scaled toward policy change. Mark R. Warren and Etienne Wenger, representing learning ecologies and communities of practice, emphasize distributed leadership and cross-actor collaboration that sustain networked organizing in the contemporary era.
