Michael Sailer investigates how and to what extent game design elements used in gamification can influence motivation and performance. In addition to a detailed review of the state of research in different fields of application, two empirical studies in the context of manual work processes are carried out, which show that gamification can be an effective measure. Gamification can contribute to the fulfillment of basic psychological needs that have a motivating effect and can promote the quality and quantity of the performance provided.
