• Develop demand plans for new product introductions, product transitions, engineering changes, phase-outs, and discontinuations.
• Identify and quantify demand risks and opportunities, develop planning scenarios, and communicate recommendations to leadership.
• Work closely with Supply Planning to balance customer demand with production capacity, material availability, lead times, and inventory objectives.
• Drive continuous improvement in demand-planning processes, systems, reporting, data quality, and cross-functional collaboration.
• Evaluate and apply advanced analytics, automation, and AI or machine-learning forecasting capabilities where appropriate.
• Prepare and present demand reviews, KPI dashboards, forecast scenarios, and executive-level summaries.
• Establish demand-planning policies, procedures, and best practices that support scalable and consistent business processes.
