Review Questions

• How does safety stock help manage uncertainty in supply and demand?
  • Safety stock serves as a buffer against unpredictable fluctuations in supply and demand. By holding extra inventory, businesses can better handle scenarios such as sudden spikes in customer orders or delays in receiving products from suppliers. This proactive approach minimizes the risk of stockouts, ensuring that customer needs are met even in uncertain conditions.
• Evaluate the trade-offs involved in determining the optimal level of safety stock for a business.
  • Determining the optimal level of safety stock involves balancing the risks of stockouts against the costs associated with holding excess inventory. If a business holds too much safety stock, it incurs higher carrying costs, including storage and insurance expenses. Conversely, if it holds too little, it risks losing sales and damaging customer relationships due to unmet demand. Effective inventory management must carefully analyze these trade-offs while considering lead times and market conditions.
