Behavioral
During a peak season, the logistics team prioritized expedited shipments, causing the production line to run out of critical components.
Align both teams to ensure timely component delivery without disrupting production schedules.
Facilitated a joint meeting, mapped the end‑to‑end flow, introduced a buffer inventory policy, and set up a real‑time dashboard for inventory levels visible to both teams.
Conflict resolved within two weeks, on‑time delivery improved by 15%, and production downtime dropped by 20%.

Case Study
The retailer reports weekly stockouts of a bestselling gadget despite stable sales history.
Identify root causes and develop a solution to eliminate stockouts while controlling inventory costs.
Extract sales and inventory data, perform demand variability analysis, evaluate lead time reliability, conduct a root‑cause analysis (forecast error, supplier lead time, safety stock policy), and propose a revised safety stock model with dynamic reorder points. Present findings to merchandising and supply planning teams for implementation.
Implemented dynamic reorder points, reducing stockouts by 85% within two months and decreasing excess inventory by 12%.
