This literature study reviews user-driven innovation and establishes a typology of its forms in a tourism context. Sixteen methods are distinguishable. They comprise situations where users are actively involved and methods where information is collected without direct user involvement. The nature and intensity of the dialogue between companies and their customers are addressed. Drawing on this existing research, the article concludes that there is still little comprehensive follow-up on user-driven innovation in tourism and its impact on quality improvements and assurance. Key areas for future studies are identified.
