01 / Business Problem

The challenge.

Supply chain leaders lacked a unified view of delivery performance, inventory health and supplier risk — making it hard to spot stockout risks, late shipments and underperforming suppliers before they hit revenue.

03 / Data Source

Where the data came from.

Source

Operational supply chain dataset covering shipments, warehouses, suppliers and SKU-level inventory, combined with supplier scorecards and lead-time logs.

Dataset

Multi-table dataset with shipment-level records (origin, destination, carrier, lead time, on-time status), SKU inventory snapshots, supplier master data with risk attributes, and historical demand by region.

04 / Methodology

How the analysis was built.

Step 01

Data Cleaning

Consolidated shipment, inventory and supplier tables, standardized location and SKU codes, removed duplicate shipment events and engineered lead-time, on-time-flag and risk-tier fields.

Step 02

SQL Analysis

Wrote SQL with CTEs and window functions to compute on-time delivery %, rolling lead times, inventory turnover, days-of-supply and supplier risk scores; validated against operational benchmarks.

Step 03

Dashboard Development

Built a multi-page Power BI report — executive KPI overview, warehouse and route performance, inventory health, and a supplier risk page with drill-through to SKU-level stockout risk.

05 / Key Insights

What the data revealed.

On-time delivery drops ~9 points on long-haul routes through two specific transit hubs — a clear bottleneck.

Roughly 18% of SKUs drive 80% of stockout incidents, concentrated in fast-moving categories with low safety stock.

Top 12 suppliers contribute 65% of late shipments, mostly tied to extended lead-time variability.

Regional demand spikes are predictable from prior-month patterns but inventory is not pre-positioned accordingly.

06 / Recommendations

What the business should do next.

Reroute long-haul shipments away from the two bottleneck hubs or add a buffer transit day in planning.

Raise safety stock on the top 18% stockout-prone SKUs and review reorder points monthly.

Move the 12 high-risk suppliers to a weekly performance review and qualify backup suppliers for critical SKUs.

Pre-position inventory in high-demand regions based on the rolling 3-month demand forecast.
