| Summary: | 碩士 === 國立交通大學 === 工業工程與管理系所 === 93 === In a severe competitive environment, industries can only survive through continuously product innovation to create business values. Product innovation was technology-driven in the past days, as product technologies mature and the market structures change, industries must substitute their business strategies into user-centered strategies to satisfy new customers’ needs. Scenario-based design is one of the most useful tools in user-centered design product innovations. Scenario-based design works well, however it still needs a constructing structure for designers to follow. In this study, we establish a five W scenarios constructing structure to solve some disturbing problems while using scenario-based design methods. In addition, we explore DTV service needs as a case study to verify our five W scenario-based design structure and provide some concrete referable design guidelines while designs construct scenarios.
