Bottlenecks in production, supply and sales have been found and resolved. The holding's factories, saved by Alex Rogo using the "drum-buffer-rope" principle in the book "The Goal", work like clockwork. And with all this, they turn out to be useless assets in the eyes of the managers of the managing holding. However, the theory of constraints, which worked well at the operational level, helps here too. The book will be useful to managers of production sites and employees of management companies.
