The four dimensions of supplier assessment: quality, delivery time, cost and service.
1. Quality metrics
Quality is the most basic metric used to measure suppliers. Each purchaser has its own standards in this regard, requiring suppliers to comply. Supplier quality indicators mainly include incoming material batch pass rate, incoming material sampling defect rate, incoming material online scrap rate, supplier incoming material exemption rate and so on.
The incoming material batch pass rate = (qualified incoming material batch / incoming material total batch) × 100% incoming material sampling defects rate = (the total number of sampling defects / the total number of sampling samples) × 100%, incoming material online scrap rate = incoming material total number of scraps (including online production found) / the total number of incoming material × 100%; incoming material exemption rate = (incoming material exemption of various types of number of products supplied by the supplier / total number of products) × 100%
Supplier quality indicators mainly include the incoming material batch pass rate, incoming material sampling defects rate, incoming material online scrap rate, supplier incoming material exemption rate, and other quality indicators. 100%
2, supply indicators
Supplier's supply indicators, also known as corporate indicators, is with the supplier's delivery performance and the supplier's planning and management level of the assessment factors, the most important of which is the rate of on-time delivery, delivery lead time, the acceptance of changes in the rate of orders, and so on. On-time delivery rate: On-time delivery rate = (on-time delivery of the actual batch / order confirmed delivery of the total number of batches) × 100%
Delivery cycle: The delivery cycle refers to the length of time from the date of the order to the time of delivery, generally calculated in days. Order change acceptance rate: order change acceptance rate is a measure of the sensitivity of the supplier's response to changes in the order of an indicator, refers to the two sides to confirm the delivery cycle in the supplier can accept the increase or decrease in the rate of the order.
3, economic indicators
Supplier assessment of economic indicators are mainly considered purchase price and cost. Unlike quality and supplier indicators, quality and supply assessment on a monthly basis, while economic indicators are often assessed on a quarterly basis. Another difference with quality and supply indicators is that economic indicators are often qualitative and difficult to quantify, while the former are quantitative indicators.
4, the price level
Enterprises can compare their own purchasing price with the company's grasp of the market situation, but also based on the actual cost structure of the supplier and profit margins and other subjective judgment.
