Drive continuous improvement in planning processes, including automation, BOM clean-up, and lead-time reduction initiatives. Ensure compliance with company purchasing policies, import/export requirements, and record-keeping. Implement data-driven inventory management strategies to mitigate material risks, such as Excess and &Obsolete (E&O) and Purchase Price Variances (PPV).
