Safety Stock in Supply Chain Management

When it comes to supply chain management, safety stock is crucial. This approach is intended to increase profitability, foresee changes in market demand, and facilitate the scheduling of the production of commodities. Since the market’s conditions continually affect the law of supply and demand, if the market is always changing and volatile, businesses must use safety stock to foresee shifts in demand and maximize earnings.

To calculate the precise quantity of inventory, safety stock is also necessary. The flow of money in the company’s trading capital will halt if there is too much inventory. On the other hand, if there is insufficient stock, the business will experience a stock out.

Demand changes, incorrect forecast implementation, and a wide range of lead times are some variables that contribute to stock outs for businesses. Since more service levels are directly linked to stock outs, safety stock can be employed to reduce stock outs.
