Although quality is known to man and has been with it since ancient times, the interest in her has increased, and her more detailed study is due to the emergence of mass production. Along with the development of science and technology, the needs of the company are being developed to achieve the highest level of quality and thus the achievement of competitive advantage. Kaizen is a system of continuous and gradual improvement: the quality, technology, process, culture and productivity of the organization. It came to Japan after the Second World War, and the name comes from the word kai meaning change and the word zen means goodbye. Kaizen marks the philosophy of life and work that brings continuous, incremental and everyday improvements. It is a way of managing a company focused on advancement, and it can also be applied to other aspects of an individual's life. One day should not go without improvement, and when progress has been made, it is necessary to standardize it and look for a new one. The importance of Japanese manufacturing philosophy is significant because it is based on clear criteria of related unbridled processes, warehouses that do not burden stocks, with constant rationalization of the process, constant improvement and development in all segments of work. Because of this, Kaizen's concept of continuous improvement of business processes is one of the most important concepts of operational and logistic management today in world business practice, and this is the constant need for cutting and eliminating all unnecessary costs. The most important thing in the whole concept is to make Kaizen and his principles move to the habit of every employee and to continue with its application after successful application and visible first results because the good is never good enough and there are always place for improvement.
