Birger Sevaldson of the Oslo School of Architecture and Design first introduced the gigamap technique. The gigamap takes an architectural and descriptive approach to complex projects. The technique has been extended to synthesis maps and system design complexity maps.
The synthesis map is used at OCAD University to translate multiple knowledge perspectives and illustrate the dilemmas and challenges within a complex system scenario. System design complexity maps are the outcome of an academic project at the National Institute of Design. They use metaphor and a central theme to make complex issues accessible for sharing and participatory work with multiple stakeholders.
