Why is it important to maintain a buffer stock of essential supplies, and how is a minimum stock level determined?

• A. To avoid stockouts during surge; determine based on consumption rates, lead times, and hazard duration.
• B. To minimize storage costs by keeping stock low.
• C. To maximize procurement orders regardless of lead times.
• D. To hide inventory data from partners.

Answer: (A)

Having a buffer stock helps ensure essential supplies stay available when demand spikes or delivery times stretch due to a disaster. The minimum stock level is set to cover what you’ll use during the replenishment period (the lead time) plus extra for the duration of the hazard itself. Practically, you estimate how much you use on a normal basis, multiply by the lead time to see how much you must have on hand before a new order arrives, and then add a cushion for the hazard duration to account for longer or more intense needs or delays. This approach protects service delivery when supplies are disrupted or demand is unpredictable.

Other ideas that focus only on lowering stock, pushing more orders without regard to delivery times, or hiding inventory data don’t help ensure continuity during emergencies.
