The word quality is the concept of everyday and wide application. There are many aspects in which the word quality can be used. But no matter what these aspects are about, there will always be a question of what quality really is, how unique is it, and what is its definition. The interest in quality began to appear unmistakably with the appearance of man, and she had great importance throughout history, but her systematic study started in the period following the great industrial revolution. Recently, the meaning of quality has grown tremendously. Product quality can be said to be the result of growing but still growing customer needs, and this should be linked to a strong strengthening of competition through the globalization of the world market and the development of modern technology. The company's true response to such challenges is to continually improve its quality by adopting contemporary philosophies and approaches to quality, and on the basis of its developed and implemented quality management systems. International ISO standards are prerequisites for ensuring the required product quality. In modern companies of highly developed countries there is a trend of increasing the implementation of ISO standards. In the "Maestral Hotels" company successfully implemented a quality management system and a food safety management system.
