Operations & Supply Chain Analytics

SQL for ops & supply-chain analysts — inventory turns, on-time delivery, supplier scorecards, demand-forecast variance.

30 missions|7 tables
  • Show me the warehouses
  • Average lead time per supplier
  • Demand week-over-week change
  • Real Supplier ScorecardsOn-time delivery, lead time, and chronic-late-shipment patterns across 8 suppliers and a ghost row.
  • Inventory Health QueriesLatest-snapshot dedup, days-of-supply alerts, stock-out risk — the queries warehouse leads run every morning.
  • Demand vs PlanMAPE forecast accuracy, the S&OP-review metric every demand planner ships weekly.

Logistics & Transportation Analytics

Carrier OTIF, freight invoice audits, detention hot spots, cost-per-unit benchmarking, and multi-metric carrier scorecards — the full logistics & transportation analyst SQL curriculum across 30 missions.

30 missions|5 tables
  • Meet the carrier network
  • Monthly shipment volume trend
  • Carrier OTD vs. target gap
  • OTIF Compound MetricBuild the on-time AND in-full formula at PO-line grain — the exact logic Walmart enforces with a 3% COGS chargeback.
  • Freight Invoice AuditsFind overbilled invoices, accessorial overcharges, and contract rate violations across carriers and lanes.
  • Detention AnalysisIdentify facilities where dwell time exceeds 2 hours on more than a third of shipments — the hidden cost every logistics manager wants to cut.

Procurement & Sourcing Analytics

PO cycle time analysis, purchase price variance, maverick spend detection, three-way match exceptions, and supplier risk scorecards — the full procurement & sourcing analyst SQL curriculum across 30 missions.

30 missions|6 tables
  • Category catalog
  • Top 10 suppliers by spend
  • Contract compliance rate
  • PO Lifecycle AnalysisTrace the full req → PO → ASN → receipt → invoice cycle and measure cycle time at every stage.
  • Purchase Price VarianceCompare actual vs contracted unit price to surface PPV exceedances by category — the metric that drives finance escalations.
  • Maverick Spend DetectionFind POs with no contract_id — off-contract spend that bypasses negotiated pricing.

Warehouse Operations Analytics

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.

30 missions|7 tables
  • Worker roster
  • Pick accuracy
  • Labor by function
  • UPLH by Zone and ShiftCompute units per labor hour across picking zones and shifts — the metric DC managers review every morning.
  • Dock-to-Stock DecompositionBreak the inbound cycle into unload, count, and putaway phases to find the bottleneck causing SLA breaches.
  • Pick Accuracy Heat MapRank zones by pick error rate — surface the OVERFLOW zone pattern where error rates are 4× higher than GOLDEN.

Demand Planning & Forecasting Analytics

WMAPE calculation, forecast bias detection, tracking signal computation, consensus vs statistical forecast value-add, promo lift attribution, and ABC×XYZ segmentation — the full demand planning analyst SQL curriculum across 30 missions.

30 missions|6 tables
  • Location count
  • WMAPE
  • Forecast value-add
  • WMAPE vs MAPELearn why WMAPE (Σ|A−F|/ΣA) is the industry default — it weights by volume and avoids divide-by-zero on intermittent SKUs.
  • Forecast Bias DetectionSpot the systematic over-forecast on Category C that hides inside an acceptable WMAPE — the pattern demand planners escalate to leadership.
  • Tracking SignalCompute rolling tracking signals and flag SKUs where |TS| > 4 — the statistical trigger for model recalibration.
