Business Origami, also called desktop system mapping, is a facilitation technique developed by Hitachi Design Center that uses small paper cutouts representing people, places, devices, and documents to model a service system on a flat tabletop. Participants arrange and rearrange the cutouts to represent different service configurations, communication flows, and actor relationships. Because the model is three-dimensional, physical, and easily rearranged, it enables collaborative system design in a way that diagram-drawing tools rarely achieve.
