Building digital twins is a cross-disciplinary endeavor, combining the efforts of modelers, system engineers, data analysts, UX designers and domain experts. For digital twins to be able to evolve with their paired, real-world system, the artifacts associated with these various disciplines must remain synchronized and coherent throughout the digital twin lifecycle. We provide a paradigm for harmonizing this multi-disciplinary effort using an Authoritative Broker of Truth (ABoT) and apply this paradigm to a real-world case study: Can I cut the cord on my cable provider?
