Thorsten Pieper explores the impact of innovation barriers along the user innovation process
in particular whether technological social legal and ownership barriers change the properties
of user-developed products. This study roots from the open innovation research field and
reveals insights from innovating users in collaborative workspaces. The results prove a
hierarchical allocation of innovation barriers regarding their influence on the end-product and
moderating influences of user innovators' personal characteristics. The author discusses these
insights and provides practical recommendations for more efficient promotion of user
innovations and successful integration in corporate co-creation projects.
