Regional demand growth 20% but DC volume flat YoY

Did demand mix shift away from this DC?

Bulk orders (60% of revenue) shifted to closer regional DC

Shipments to DC: 450K units/month (flat) vs 3 years ago: 450K

Is the 60% utilization a real constraint, or a utilization metric issue?

Storage space constraint?

Square footage available: 250K sqft; current usage: 150K (60%)

High-velocity items use 8 sqft/unit; seasonal ramps use 15 sqft/unit

Throughput bottleneck (labeling, packing, shipping)?

Peak packing capacity: 12K units/day; running at 6.5K/day (54%)

Shipping dock capacity: 180 trucks/day; using 90 trucks/day (50%)

Is the network design misaligned with demand geography?

Is this DC in the optimal location for serving its market?

Average inbound-to-customer distance: 240 miles (up from 180 miles 3 years ago)

Two competitor DCs opened within 60-mile radius in past 18 months
