What is Economic Order Quantity and when is it most useful in sustainment planning?

• A. EOQ is the maximum inventory level that triggers a reorder.
• B. EOQ is the quarterly budgeted quantity for procurement.
• C. EOQ is the minimum quantity to order to meet safety stock.
• D. EOQ is the economic order quantity that minimizes total holding and ordering costs; most useful when demand is reasonably stable and lead times known.

Answer: (D)

Economic Order Quantity is the quantity you order each time that minimizes the total costs of ordering and holding inventory. It works by balancing the fixed cost of placing an order against the carrying costs of keeping stock on hand. The optimal order size, often summarized by the EOQ formula, reduces overall inventory costs, making it most useful when demand is fairly stable and lead times are known because those conditions keep usage and replenishment patterns predictable. It isn’t about a maximum stock level to trigger a reorder, a quarterly budgeting quantity, or a minimum to meet safety stock—those concepts relate to when to order or how much cushion to hold, whereas EOQ focuses on the size of the order to minimize total costs.
