What purpose does safety stock serve?

Safety stock serves as a buffer against uncertainty in both demand and supply. The main purpose of maintaining safety stock is to protect against fluctuations that can lead to stockouts. Variability in customer demand, unexpected delays in lead times, and other disruptions can affect inventory levels. By holding safety stock, businesses can ensure that they can continue to meet customer needs without interruption, even when actual demand exceeds forecasted levels or when supply chain issues arise. This is particularly important in environments where customer service and fulfillment are critical for maintaining competitiveness. While other options may hint at inventory management strategies, the fundamental role of safety stock primarily revolves around its protective function against uncertainty.
