The focus of the Minitrack for HICSS-55 is smart service systems in the AI era. Smart service systems are a growing topic of study in both the information systems, systems science and service science literature. The coming decade will witness the innovation of smart service systems driven by AI and intelligent agents, both for automation and augmentation. Applying the appropriate management, organizational, architectural, technological and design methodologies related to this innovation of smarter and wiser service systems is much needed. The goal of this track is to explore the challenges, issues and opportunities related to innovation of smart service systems that enable value co-creation with artificial intelligence, people, analytics and organizations. We are interested in novel theories, approaches and applications for innovation of smart service systems.
