What is the method of supplier performance evaluation?

Generally speaking, purchasing personnel usually evaluate suppliers in terms of price, quality, delivery, cooperation (service) and so on, and calculate the score in the form of a percentage system. As for how to allocate points, companies can decide their own prices according to specific conditions: according to the lowest price, highest price, average price and self-evaluation of similar materials in the market, a more standard and reasonable price can be calculated. Quality rejection rate: quality is judged according to the rejection rate within a certain period of time (such as one month, one quarter, six months and one year). For example, if a supplier delivers 50 batches in the first half of the year and rejects 3 batches, the rejection rate is 3 ÷ 50 * 100% = 6%. The higher the rejection rate, the worse the quality and the higher the score. Average qualified rate: according to the qualified rate of each delivery, calculate the average qualified rate in a fixed time to judge the quality. For example, on June 5438+ 10, a supplier delivered goods for three times, and the qualified rates were 90%, 85% and 95% respectively, so the average qualified rate =(90%+85%+95%)÷3=90%, and the higher the qualified rate. Total qualified rate: judge the quality according to the total qualified rate in a fixed time. For example, a supplier delivered 10000 pieces in five batches in the first quarter, and the total qualified number was 9850 pieces, then the qualified rate = 9850 ÷1000 *100% = 98.5%.
