The need for efficient production organization in modern economic conditions forces machine-building enterprises to introduce and maintain the functioning of various production systems based on lean manufacturing principles. One of the prerequisites for the qualitative training of graduates for such enterprises is the formation of their competence in the field of lean production. The system approach to the formation of these competences is considered. The basis is based on modern educational technologies that ensure the activation of educational and cognitive activities of students and the effectiveness of the educational process in general.
