Supply chain planners create demand forecasts, manage replenishment cycles, coordinate material availability, and balance inventory levels across the network. They work with forecasting models, production schedules, supplier lead times, and sales inputs to create accurate operational plans. Their work ensures smooth manufacturing flow, prevents shortages, and reduces excess stock. They collaborate with logistics, procurement, production, and commercial teams to align planning decisions. Increased supply complexities and rapid market changes have made planners essential for maintaining responsive and efficient supply chains.
