Gamification is a novel method to improve engagement, motivation, or participation in non-game contexts using game mechanics. To a large extent, gamification is a psychological- and design-oriented discipline, i.e., a lot of effort has to be spent already in the design phase of a gamification project. Subsequently, the design is implemented in information systems such as portals or enterprise resource planning applications. These systems act as mediators to transport a gameful design to its users. However, the efforts for the subsequent development and integration process are often underestimated. In fact, most conceptual gamification designs are never implemented due to the high development costs that arise from building the gamification solution from scratch, imprecise design or technical requirements, and communication conflicts between different stakeholders in the project. This thesis addresses these problems by systematically defining the phases and stakeholders of the overall gamification process. Furthermore, the thesis rigorously defines the conceptual requirements of gamification based on a broad literature review. The identified conceptual requirements are mapped to a domain-specific language, called the Gamification Modeling Language. Moreover, this thesis analyzes 29 existing gamification solutions that aim to decrease the implementation efforts of gamification. However, using the different language elements, it is shown that none of the existing solutions suffices all requirements. Therefore, a generic and reusable platform as runtime environment for gamification is proposed which fulfills all presented functional and non-functional requirements. As another benefit, it is shown how the Gamification Modeling Language can be automatically compiled into code for the gamification runtime environment and, thus, further reduces development efforts. Based on the developed artifacts and five real gamified applications from industry, it is shown that the efforts for the implementation of the gamification can be significantly reduced from several months or weeks to a few days. Since the technology is designed as a reusable service, future projects benefit continuously with regards to time and efforts. |
