Each tier in the supply chain or supply network on the supplier side of Karl-Heinz Buehne involves a single risk. The more tiers, the more difficult it is to analyze and monitor the business partners. Suppliers of suppliers are generally unknown, so there is already an increasing risk at the second (Tier 2) level. If e.g. a first Tier supplier is not adding any value, the supply chain can be shortened and the risk of failure can be minimized by skipping this supplier. A previous Tier-2 supplier now turns into a Tier-1 supplier, which we call "go-direct". In our tool Supply Chain Intelligence as far as international suppliers are concerned, this analysis can be done with one click: Analyze the potential of shortening and therefore stabilizing the supply chain of Karl-Heinz Buehne
