Twice a year we monitor the performance of our suppliers by executing a Supplier Performance Rating. It helps our suppliers to maintain and expand their own competitiveness.
Depending on the commodity we rate the following criteria:
- Quality 
- Procurement 
- Logistic 
- Technology & Innovation 
- Sustainability 
If the results are weak, we expect our suppliers to explain the causes and take improvement measures.
Below you find the Performance Rating criteria explanations. With go-live of our Supplier Portal, we provide the rating results and track corrective measures via this tool.
