Conducting action research with large global systems presents particular challenges. A major one is the need to easily and succinctly present complexity in a way that is meaningful for stakeholders and supports developing their connections to take effective joint action. The Global Finance Initiative (GFI) explored the use of three different visual mapping methodologies to help address this challenge. These are associated with social network analysis methodologies. But of course other issues with a global action research project also are significant. Identifying participants requires selecting from billions of people who are stakeholders. Additionally, this project also explored the role of action researchers as initiators of change, rather than ones invited into a change arena. To address some of these challenges, this article draws from the GFI experience and proposes an eight-step methodology.
