We present an innovative, cooperative, and competitive multiplayer serious game, suited for the educational needs of supply chain and operation management post-graduate students. Hence, the objective is to satisfy the ever-increasing requirement of students to have the ability to experience and practice the theory learned in traditional ways, for active knowledge acquisition. To cope with such needs, we designed and implemented a multiplayer online serious game, that provides players with a realistic industrial experience, and teaches them how to take a whole range of day-to day and medium-term challenging decisions. Learners are divided into teams, each one representing an Original Equipment Manufacturer (OEM), in every team the students will collaborate and will compete in the same market, and sharing a limited set of suppliers. To this aim they have to define a strategy to target the best market segmentation. Teachers have the possibility to investigate the decision patters of the learners, analyze KPIs and learning analytics, to better understand the learning process and guide the learners in their educational journey. By means of a preliminary questionnaire, the interest in using the serious game to study operation management was confirmed. In addition, the game was tested by a small group of students, who acknowledged the effectiveness of the game's dynamics as a tool to complement traditional teaching methods.
