Abstract
The paper deals with the optimization of production processes and the setting of criteria for reducing production costs. Any company is not just a leap in production, but a lean has to be gradually transferred to all its activities. This created the concept of a lean company first. The skill of an enterprise is to perform only the activities that are needed, to do them right for the first time, to make them faster than others and to spend less resources at the same time. The company's business is that the company does exactly what the customer wants, with a minimum number of activities that do not add value to the product or service. The Lean Production System focuses mainly on eliminating waste in every activity of the manufacturing enterprise.
