The article presents the results of implementing a quality management system at the enterprise. The study and analysis of the international standard ISO 9001:2015, as well as sanitary and epidemiological requirements for production control were carried out. The main requirements and rules for the implementation of input, operational and output control of products at enterprises at all stages of the product life cycle were identified and presented. In addition, it was determined what requirements must be met by enterprises to implement a quality management system. It is important to note that this work is necessary at the enterprise, as it has the following advantages: by improving product quality, product sales increase, the level of management of the enterprise and personnel increases, and cost savings are realized at the stages of development, production and operation. It follows that to implement a quality management system, it is necessary to set the following tasks: describe the company's processes, develop performance criteria and evaluate processes, develop the necessary documented information, implement documentation in all departments, familiarize them with the quality policy and goals, conduct timely internal audits for further SWOT analysis, and conduct an assessment by an external auditor in order to obtain a certificate of compliance. An important step in quality management is that the organization should not eliminate nonconforming results of processes, but should identify potential nonconformities, assess the risk with the preparation of a Protocol, plan and implement actions to reduce risks. Difficulties may arise: lack of understanding by the staff of the need to implement a quality management system, lack of a clear vision, mission, lack of complete information on processes, lack of quantitative and qualitative evaluation criteria, quality is defined as the quality of products, not as the quality of processes, resources, lack of monitoring of customer satisfaction. It is possible to overcome these difficulties only with the implementation of the quality management system according to ISO 9001, since the requirements prescribed in the international standard are a real tool for improving the efficiency of the enterprise, which will help bring the organization to a higher level of development.
