Operations scorecard

Ship the SQL DC managers check every morning

A warehouse operations star schema: 5 zones (GOLDEN/STANDARD/BULK/COLD/HAZMAT), 20 workers, 40 SKUs, 80 inbound receipts, 500 pick tasks, 120 inventory positions, 90 cycle counts. Planted data-quality issues: NIGHT shift UPLH is 18% below DAY; OVERFLOW zone pick error rate 4× GOLDEN; dock door 3 has 2× average dock-to-stock time; 12 A-class SKUs currently in BULK zone (slotting mismatch).

Units per labor hour, dock-to-stock decomposition, pick accuracy by zone, slotting recommendations, and wave analysis — the full warehouse operations analyst SQL curriculum across 30 missions.

Compute units per labor hour across picking zones and shifts — the metric DC managers review every morning.

UPLH by Zone and Shift

Break the inbound cycle into unload, count, and putaway phases to find the bottleneck causing SLA breaches.

Dock-to-Stock Decomposition

Rank zones by pick error rate — surface the OVERFLOW zone pattern where error rates are 4× higher than GOLDEN.

Pick Accuracy Heat Map

Cross ABC velocity analysis with current zone assignments to identify misslotted A-class SKUs wasting travel time.
