Kanban is a method for managing how work flows through a business, originally created by Toyota for manufacturing but now used in many industries. Think of it like a smart traffic light system that controls the flow of work to prevent bottlenecks and excess inventory. It uses visual boards or cards to track work items, making it easy to see what needs to be done, what's in progress, and what's finished. Similar systems include Just-In-Time (JIT) production and pull systems. Companies use Kanban to reduce waste, improve efficiency, and keep inventory levels exactly where they need to be. You might hear it called a "visual management system" or "pull-based inventory management."
