Where does work queue?
Look for repeated waits, congestion, and uneven workload between process steps.
Warehouse performance depends on how inventory, labor, space, and information move through a sequence of connected tasks.
The exact process differs by operation, but a clear map gives teams a shared way to discuss time, quality, and capacity constraints.
Throughput measures completed work over time. Order cycle time follows an order from release to completion. Inventory accuracy compares system records with what is physically available. Pick accuracy tracks whether the right items and quantities were selected.
Each metric needs a clear start point, end point, and denominator. A faster pick rate may not improve customer service if packing errors rise or replenishment cannot keep pace.
The best improvement often begins with understanding the process as it actually runs.
Look for repeated waits, congestion, and uneven workload between process steps.
Find data errors, damage, mispicks, relabeling, and avoidable touches.
Check how order mix, staffing, cutoffs, and replenishment alter the flow.
