Today, the role of suppliers in procurement activities is growing, and, accordingly, a qualitative assessment of their activities is of particular importance. The production of medical devices (MD) is subjected to especially strict control. Their quality, efficiency and safety directly depend on the quality of purchased raw materials, semi finished products, services and, as a result, on the work of suppliers. The combination of these factors ensures the competitiveness of the medical device manufacturer in the medical device market. However, most of the standards that describe the procedure for conducting audits do not contain requirements for a second party audit. Therefore, manufacturers are forced to develop their own methods and standards governing this process. In this regard, we have developed a method for selecting and evaluating suppliers at the design stage of medical devices. The essence of the method: each customer enterprise establishes a set of requirements that provides the most acceptable audit solutions for it and the selection of an ideal supplier of raw materials. The ideal supplier will be a company that meets all the requirements of the customer enterprise.
