The practice of working with business cases contradicts all basic school education organizations' canons. Judge for yourself: the authors of the cases do not know initially how to solve them. They often do not even guess which methods they should use to do so. Moreover, they are not always sure that they formulate the problem correctly. However, students for some reason find such problems to be the most interesting to solve. The middle adolescence is the age when young people are in search of themselves. Therefore, these cases, dictated by the chaos of a changing life, serve as a real window to the world of future destiny for them. The chapter will consider the process of selecting enterprises that can become the authors of cases, reveal the stages of case creation, describe the problems that the designers of cases are faced with, analyze in detail the experience of organizing the educational process based on cases with schoolchildren, and provide examples of high quality scientific and technological cases.
