5. Discussion
5.1. Summary In this paper we use a sample of 864 employees (283 ideas) and 239 users (66 ideas) to investigate whether internal lead users generate better ideas (in terms of originality, user value, and market potential) than ordinary employees, external lead users, and ordinary users. Our predictions are not fully supported: internal lead users generate ideas of higher originality and user value than ordinary employees and users do, but the highest quality ideas measured on those dimensions come from external lead users. In relation to market potential, location of the individual inside or outside the organizational boundary has no effect: internal and externalleadusersproduce ideas withhighermarketpotentialthan the ideas of ordinary users and ordinary employees.
