Which statement is a function of inventory?

• A. To buffer against uncertainty in demand and/or supply
• B. To maximize production backlog
• C. To increase lead times
• D. To minimize supplier diversity

Answer: (A)

Inventory mainly functions as a buffer against variability in demand and supply. By holding extra stock, a company can continue fulfilling orders even when demand spikes or when a supplier is late or capacity is constrained. This decouples different parts of the supply chain, allowing production and delivery to proceed smoothly rather than stopping at the worst times. Of course, carrying inventory incurs costs and risks like obsolescence, but its purpose is to absorb uncertainty and protect service levels. The other statements describe outcomes that inventory does not purposefully achieve: increasing backlog, extending lead times, or forcing fewer supplier options are not functions of holding inventory.
