The role of the Gigamapis 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 understanding better 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.
