The network nature of the organization makes it possible to ensure the self-improvement of the proposed system and bring it to the level of artificial evolution, which will avoid the need for constant modernization and the inevitable delays and errors associated with the adoption and debugging of the upgraded system. The evolutionary scenario allows to improve the system in the process of its operation without the need to change the generations of services, retrain employees, making do with minimal support and maintenance. The effectiveness of the proposed system is ensured by the modern educational motto of digital development “improvement at work”.
