In replenishment, what term describes the signal from WMS that prompts replenishment?

• A. Minimum stock level.
• B. Demand-driven signal.
• C. Inventory aging.
• D. Dock receipt.

Answer: (B)

The signal being tested is a demand-driven signal. In replenishment, the WMS tracks actual usage and consumption, so as items are picked and on-hand inventory falls, the system generates a demand-driven signal that prompts replenishment from reserve stock or the supplier. This ties replenishment directly to real demand rather than to a fixed calendar or to the age of inventory.

Minimum stock level is a threshold that can trigger reordering in some setups, but it’s the threshold, not the signal itself. Inventory aging refers to how long items have sat in stock, which isn’t the trigger for replenishment. Dock receipt is simply a receiving document, not a replenishment trigger.
