A grocery store sends daily reports of dairy sales to the supplier, who then decides deliveries. Which strategy is used?

A lean supply chain focuses on minimizing waste and maximizing efficiency by reducing excess inventory and optimizing processes. While it seeks efficiency, it does not specifically involve the supplier managing inventory based on sales data from the retailer, which is a hallmark of vendor-managed inventory.

Backward vertical integration occurs when a company takes control of its supply chain by acquiring or merging with suppliers. This strategy does not apply in the context of the grocery store and supplier relationship described, as there is no indication of the grocery store acquiring the supplier or managing inventory beyond sales reporting.

An agile supply chain emphasizes flexibility and responsiveness to changing customer demands. While it is important for adapting to market fluctuations, it does not specifically involve the direct management of inventory by the supplier, which distinguishes it from vendor-managed inventory practices.
