Review Questions

• How does safety stock level contribute to effective inventory management?
  • Safety stock level plays a vital role in effective inventory management by acting as a buffer against uncertainties in demand and supply. By keeping additional inventory on hand, businesses can reduce the risk of stockouts that may arise from sudden increases in customer demand or delays in supplier deliveries. This practice ensures that operations run smoothly and customer satisfaction remains high, highlighting the importance of a well-calculated safety stock strategy.

  • The determination of safety stock levels is influenced by several factors including lead times, demand variability, and service level goals. In volatile market conditions, where demand may fluctuate significantly, businesses may opt to increase their safety stock to mitigate risks of running out of inventory. Conversely, in stable markets with predictable demand, lower safety stocks may suffice, allowing companies to reduce holding costs while still meeting customer expectations.
