Dr. Edwards Deming, whose 120th birthday falls on October 14, 2020, has made outstanding contributions to management theory and practice, mathematical statistics and many other areas of human endeavor. This work, written for the anniversary of E. Deming, examines the paradoxes arising from his teachings. They relate, inter alia, to competition, motivation and remuneration, the use of sampling methods, on-the-job training, operational definitions and much more. Resolving these paradoxes is the path to a deeper understanding of the modern world and to the improvement of management practice. Already during Deming’s lifetime, numerous attempts were made to revise his teachings, and now there is a desire to abandon the use and development of his heritage. This is alarming and worrying.
