Question
Why is safety stock maintained by organizations?
A. To eliminate procurement costs
B. To protect against uncertainties in demand and lead time
C. To reduce supplier competition
D. To guarantee higher profits
Answer
B. To protect against uncertainties in demand and lead time
Explanation
Safety stock acts as a buffer against variability.
Safety Stock Purpose and Function
Organizations maintain safety stock primarily to protect against uncertainties in both demand and lead time. This buffer inventory serves as insurance against unpredictable fluctuations that can disrupt operations and customer satisfaction.
Demand Uncertainty Protection
Safety stock compensates for unexpected spikes in customer demand that exceed forecasted levels. When actual orders surpass predictions, the buffer inventory ensures continuous fulfillment without stockouts. This protection is critical during seasonal variations, promotional campaigns, or market shifts that create sudden demand increases.
Lead Time Variability Management
Supplier delivery schedules rarely maintain perfect consistency. Transportation delays, production issues, quality problems, or supplier capacity constraints can extend lead times beyond normal expectations. Safety stock bridges these gaps, allowing operations to continue while awaiting replenishment orders.
Cost-Benefit Balance
While safety stock increases carrying costs through additional storage, handling, and capital investment, it prevents significantly higher costs associated with stockouts. Lost sales, emergency expediting fees, production line stoppages, and damaged customer relationships typically cost far more than maintaining appropriate buffer levels.
Calculation Factors
Safety stock levels depend on demand variability, lead time variability, desired service level, and forecast accuracy. Organizations use statistical methods to determine optimal quantities that balance protection against holding costs, ensuring operational continuity without excessive inventory investment.
