We believe that there is a significant difference in the cost structure of the production site and the office division. Methods that work effectively in the production department, in office activities are often ineffective. It is necessary, understanding the specifics and ideology of the concept of Lean production, to create and implement new methods to minimize or eliminate losses. We identified losses in the activities of a division of an educational organization of the dean’s office type, proposed their classification (typing), identified and recorded typical examples of losses by group. Then we picked up the tools of Lean production to minimize or eliminate losses in an office business processes. It turned out that to eliminate or minimize losses in the work of the dean’s office in 90% of cases, the introduction of five tools is enough. The results of our research confirm the effectiveness of Lean production tools, the need for their implementation for continuous improvement of organizations’ activities, increasing their stability and competitiveness.
