During recent years, gamification has become a popular method of enriching information technologies. Popular business analysts have made promising predictions about penetration of gamification, however, it has also been estimated that most gamifica-tion efforts will fail due to poor understanding of how gamification should be designed and implemented. Therefore, in this paper we seek to advance the understanding of best practices related to the gamifica-tion design process. We approach this research problem via a design science research approach; firstly, by synthesizing the current body of literature on gamification design methods and interviewing 25 gamification experts. Secondly, we develop a method for gamification design, based on the gathered knowledge. Finally, we conduct an evaluation of the method via interviews of 10 gamification experts. The results indicate that the developed method is comprehensive , complete and provides practical utility. We deliver a comprehensive overview of gamification guidelines and shed novel insights into the overall nature of the gamification development and design discourse.
