The role of the gigamap is constantly developing. This process has not been an intentional process but a process of discovery. By looking at some obvious roles of the gigamap closer, new concepts crystallize. This working paper reports on the rethinking of the gigamap as a tool to design a shared picture of complex systems for systemic design intervention. The role of the gigamap as a bridging device to detect and cover destructive ruptures in the design process is investigated closer. Investigating the ruptures leads to a better understanding of the qualitative features the maps depict and how these features can be shared. This leads, in the end, to a proposal for a sense-sharing model.
