What is Safety Stock?
Safety stock, or buffer stock, is a level of extra inventory kept in reserve to protect against uncertainty in supply and demand. It is a buffer that companies use to ensure that they always have enough stock to meet customer demand, even during unexpected events. Safety stock helps companies avoid stockouts and keep their customers happy.
Types of Uncertainty Safety Stock Can Protect Against
Safety stock is used to protect against a variety of uncertainties, such as:
- Demand Variability: Demand can be unpredictable, so safety stock is used to protect against sudden changes in customer needs.
- Supply Constraints: Unexpected disruptions in the supply chain can cause delays in delivery, so safety stock is used to ensure that customers can still be serviced.
- Seasonal Demands: Companies that experience seasonal demand fluctuations will use safety stock to ensure they do not run out of stock during peak times.
The Benefits of Safety Stock
The main benefit of safety stock is that it can help companies avoid stockouts. Stockouts can lead to lost customers and damage to a company’s reputation. Safety stock also allows companies to respond quickly to changes in demand, and it can help them better manage their inventory.
How to Calculate Safety Stock
Calculating the amount of safety stock needed is not an exact science, and it depends on several factors, such as the variability of demand and the lead time for replenishing stock. Companies typically use a formula that considers these factors to determine the amount of safety stock needed.
Conclusion
Safety stock is a valuable tool for companies looking to protect against unexpected events and ensure they always have enough stock to meet customer demand. It can help companies avoid stockouts and manage their inventory more effectively.
