Despite the benefits of adopting IT Service Management (ITSM) reference models, such initiatives do not always produce the expected results. The research literature in this area concludes that motivation, engagement, skills, experience, performance and willingness to change of the personnel involved are among the critical factors for an effective ITSM implementation. Gamification has the capability to improve people's motivation and engagement and to drive people's behavior to meet the objectives set. Besides, gamification is widely used in learning systems for increasing students' skills and competences. In the last years, many researchers have added gamification to their process improvement initiatives to increase the motivation and engagement of process participants and to address their behavior throughout the process. Thus, we consider that adopting gamification in ITSM processes can be an interesting area of study. In this paper, we conducted a systematic mapping study to analyze the actual state of research in the field of ITSM gamification and identify the key challenges that justify future research. The results of our study highlight the positive impact of adopting gamification in ITSM processes and that ITSM gamification is a novel an attractive research area with many action possibilities
