Review Questions

• How does buffer stock play a role in maintaining service levels for a business?
  • Buffer stock is crucial for maintaining service levels because it provides a safety net that allows businesses to meet customer demand even during unexpected fluctuations. By holding extra inventory, companies can quickly respond to increased demand without delays. This ensures that customers receive their orders on time, which is vital for customer satisfaction and retention.
• Discuss the trade-offs involved in maintaining buffer stock within a supply chain.
  • Maintaining buffer stock involves weighing the benefits of ensuring product availability against the costs associated with holding extra inventory. While buffer stock can prevent stockouts and improve service levels, it also incurs carrying costs, such as storage fees and insurance. Additionally, excessive buffer stock can lead to issues like obsolescence or waste if products are not sold within their shelf life, so businesses must find a balance that minimizes risks while controlling costs.
• Evaluate the impact of lead time variability on the required level of buffer stock for a company.
  • Lead time variability directly influences how much buffer stock a company needs to maintain. If lead times are unpredictable, companies must increase their buffer stock to account for potential delays in receiving new inventory. This is because longer or more variable lead times increase the risk of stockouts. By understanding this relationship, companies can better strategize their inventory management practices and optimize their buffer stock levels to align with expected supply chain performance.
