What causes inventory duplication in the supply chain?

• A. Consumers place the same order with multiple suppliers and keep the first one to arrive
• B. Higher safety stock policies
• C. Better demand forecasting
• D. Government regulation

Answer: (A)

Duplication in inventory happens when several parties independently hold the same item for the same customer demand because there isn’t shared visibility or commitment across the network. When a customer places the same order with multiple suppliers and keeps the first shipment that arrives, each supplier has already allocated and stocked inventory to fulfill that potential demand. If the customer then uses only one shipment, the other suppliers have still committed stock, which may be canceled or returned later, but the inventory they held was unnecessary for the actual demand. This results in extra stock across suppliers and increased carrying costs, obsolescence risk, and inefficiency throughout the supply chain. The root cause is lack of coordination and visibility rather than policy choices that affect overall stock levels or external regulations. Higher safety stock policies raise total inventory levels but don’t inherently create duplicative stock tied to the same demand. Better demand forecasting helps reduce stockouts and unnecessary safety stock, not duplication created by parallel sourcing. Government regulation isn’t a typical driver of this type of inventory duplication.
