Leveraging lessons learned from previous engagements and seeing the applicability of digital twins beyond the confines of the physical world, Fujitsu conceived the Policy Twin. Using its Policy Twin, Fujitsu helps public sector clients recreate new policies from policies generated from the clients’ existing policy documents, and, critically, according to Inomata, allows for a “Digital Rehearsal” that can be used to verify the effectiveness and impact of policies in advance, based on real-world data. He added that the policy twin approach helped Fujitsu “solve social challenges … by understanding human behavior and social movements through Social Digital Twin.” Policymakers at any level could, with Fujitsu’s help, test variations of policies and evaluate the outcomes using Policy Twin, calibrating the scenarios based on desired outcomes, all before actually implementing any changes.
