Facility operations & fulfillment

Inside the warehouse, flow is the work.

Warehouse performance depends on how inventory, labor, space, and information move through a sequence of connected tasks.

A typical order path

Find the handoffs where work waits.

The exact process differs by operation, but a clear map gives teams a shared way to discuss time, quality, and capacity constraints.

ReceiveUnload and verify inbound goods
StoreAssign a location and put away
ReplenishKeep pick locations supplied
Pick & packBuild an accurate customer order
DispatchStage, load, and confirm shipment
Observation promptWhen an order misses its ship window, trace the sequence backward. Was the item unavailable, the pick delayed, a label missing, or a carrier cutoff missed? The first visible delay may not be the root cause.
Measure the flow

Use metrics that explain the work.

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.

Design questions

Before adding automation, ask:

The best improvement often begins with understanding the process as it actually runs.

A

Where does work queue?

Look for repeated waits, congestion, and uneven workload between process steps.

B

What causes rework?

Find data errors, damage, mispicks, relabeling, and avoidable touches.

C

What changes by shift?

Check how order mix, staffing, cutoffs, and replenishment alter the flow.
