Analyzed historical demand and supplier lead times to determine optimal reorder points using EOQ models and updated parameters in SAP, which lowered annual holding costs by 8% while keeping product availability above 98%.Evaluated sales volatility for over SKUs through ABC/XYZ classification and redesigned stocking policies for each category, which reduced excess slow-moving inventory by 15% and freed warehouse space for high-turnover items.Used SAP IBP to run demand simulations for seasonal products and validated forecast accuracy with backtesting, which improved forecast precision by 12% and reduced last-minute expedited shipments.Designed and published interactive Power BI dashboards that consolidated supplier lead times, fill rates, and stockout data, which enabled planners to detect shortages 20% faster and adjust orders before customer impact.Investigated recurring out-of-stock events by applying 5 Whys, Pareto analysis, and fishbone diagrams, and identified supplier performance issues as the main driver, which cut emergency orders by 10% after corrective actions.Conducted 5S assessments at regional warehouses and standardized labeling and storage methods, which reduced picking errors by 7% and improved cycle count accuracy.Applied Lean Six Sigma control charts to monitor supplier lead-time variation and flagged unstable suppliers early, which supported renegotiation of contracts and reduced supply delays by 6%.
