In inventory management, what is the purpose of reordering levels?

• A. They ensure zero inventory
• B. They set reorder points to trigger replenishment
• C. They guarantee no stockouts
• D. They store data only

Answer: (B)

Reordering levels set the point at which you trigger a new order to refill stock, based on how much you expect to use during the supplier’s lead time plus a cushion for variability. The goal is to have enough inventory on hand to cover demand while your supplier is delivering, so you can avoid running out without holding unnecessary excess. When inventory drops to the reorder point, you place the replenishment order. The reorder level is essentially Demand during lead time plus safety stock. For example, if you expect to use 50 units per week, lead time is 2 weeks, and you keep 100 units as safety stock, the reorder level would be 50×2 + 100 = 200 units. Reaching 200 triggers a replenishment order so stock arrives before you dip below zero. This approach isn’t a guarantee of zero stockouts—unexpected spikes in demand or longer-than-expected lead times can still cause shortages—nor does it aim to eliminate inventory entirely. It also isn’t about storing data; it’s about timing replenishments to balance service levels with carrying costs.
