Although there is increasing acknowledgment that consumers can contribute useful ideas during the development of innovative services, there has been little empirical examination of how such users can best be managed in order to contribute their ideas to the fuzzy front end of new service development. The present study examines the relationship between the nature of user-created ideas regarding new technology-based services and the characteristics of the users supplying the ideas. In particular, the study investigates whether users ideas become more incremental or more radical depending on the users: (i) awareness of technological restrictions; and (ii) utilization of use experience. The results show that idea creators with high use experience who are unaware of any technological restrictions tend to produce service ideas that are more radical in nature, whereas idea creators with high use experience users who are aware of technological restrictions tend to produce service ideas that are more incremental in nature. The study provides empirical support that ordinary users involved in ideation must, to provide innovative ideas, both have a contextual use experience and not be restricted in their ideation by too much technology information and restrictions on potential feasibility
