Kanban is a concept that is commonly used in lean manufacturing and production. It is a visual system that helps in managing and controlling the flow of materials and information within the supply chain.
Kanban works on the principle of just-in-time (JIT) inventory management, where materials are only produced or ordered when they are needed, thereby reducing waste and improving efficiency. The main idea behind kanban is to have a visual representation of the inventory levels and production schedules, which enables better communication and coordination between different departments and suppliers.
