This paper describes the roles of scenario in human-centered design (HCD). Two views on HCD are described. Work-driven design view focuses on the work of user's field and context to develop a usable and useful system. Technology-driven design view starts at the sheer idea of technology to create a system which may expand a new market for new user class. This article argues that the two design views explain the characteristics of HCD and scenario has the central role. It also introduces the authors' approaches to scenario-based design in HCD.
