The article considers the conceptual approach of creating a set of development tools for active learning methods in a form of competency-based business-game studio. Competence-based business game is an information system, which aims to give a certain level of professional competence while implementing scenarios that are determined by business-process models of the domain. The structure of the gaming studio, suggests a set-theoretic representation of business-game design process. Business game can be represented as a cybernetic system with feedback, which contains both the object of management and the management system. The game is implemented as control and operating machines accordingly. For the construction of the operational machine it is proposed to use a knowledge model in the form of ontology. To represent the automate model it is proposed to use a model of managing business processes of an enterprise. A block diagram of the business-game design process is provided.
