Kanban is a visual management method originating from lean manufacturing. It involves the use of cards or visual cues to signal the need for inventory replenishment. In a retail setting, Kanban helps optimize inventory levels, reduce waste, and improve overall efficiency in the supply chain. Each Kanban card represents a specific product or SKU, and its movement triggers actions like restocking. Adopting Kanban principles enables retailers to maintain leaner inventories, minimize overstocking or stockouts, and enhance the overall flow of goods through the supply chain.
