Core Inventory Management
While conducting a monthly cycle count at a mid‑size distribution center, I discovered a 3% variance between the physical count and the ERP system for a high‑value SKU.
My task was to investigate the root cause, correct the records, and implement controls to prevent recurrence.
I reconciled the count sheet with transaction logs, identified that a recent inbound shipment had been entered twice, corrected the entry in the ERP, and updated the SOP to include a double‑check step for inbound receipts using barcode scanning.
The variance was eliminated, inventory accuracy improved to 99.8%, and the new SOP reduced similar errors by 70% over the next six months.

Behavioral
A new warehouse associate joined our team during a peak season, unfamiliar with our FIFO and cycle‑count processes.
I needed to bring them up to speed quickly while maintaining daily throughput.
I created a concise training checklist, paired the associate with a senior picker for hands‑on shadowing, and conducted a short classroom session covering our SOPs and barcode scanner usage. I also set daily check‑ins for the first week.
The associate achieved 95% accuracy on their first independent count within three days and contributed to meeting our seasonal target without any inventory discrepancies.

At my previous employer we used NetSuite for inventory management, but we faced recurring discrepancies between physical counts and system balances.
My goal was to use the ERP’s features to pinpoint gaps and enhance data integrity.
I configured automated cycle‑count schedules, set up exception alerts for variance thresholds, and integrated barcode scanners directly with NetSuite’s inventory module. I also trained staff on proper transaction entry and performed monthly audit reports using built‑in analytics.
Discrepancies dropped from an average of 2.5% to 0.4% within four months, and the audit cycle time was reduced by 30%.
