Background
About John Costa
As a demand planning advisor with over six years of experience at Dell, I specialize in optimizing global lead time management for Storage & Solutions products, ensuring 95% on-time delivery performance through the integration of planning, supply chain execution, and inventory visibility strategies. My role focuses on lead time logic, reducing early shipments, and driving cross-functional collaboration to achieve operational excellence. Leveraging expertise in forecasting, project planning, and customer delivery optimization, I have developed tools for proactive sales risk assessment and facilitated readiness reviews for new product launches. With Lean Six Sigma certification and a strong focus on cross-functional governance, I am committed to empowering teams with practical, data-driven solutions that enhance supply chain efficiency and support strategic business goals.
