It has been pointed out that the development of artificial intelligence can transform the relationship between systems and people fundamentally. Human-centered design (HCD) is a concept that realizes a human-centered system by grasping user usage and deriving user requirements from it. This design concept is still important and is effective when systematizing existing operations. However, when a user's advanced work can be replaced by artificial intelligence, the relationship between the user and the system changes dramatically, but the direction has yet to be clear. In this study, interviews with service providers on the site using artificial intelligence were conducted. This paper discusses the necessity of providing support not only for the system development but also for rebuilding the meaning and significance of the operations and actions of the people using the system.
