Kanban is a core Lean tool designed to visualize workflow, control inventory, and enhance productivity through a simple yet powerful visual management approach.
Originating from the Toyota Production System, Kanban ensures that work is pulled only when there is demand, preventing overproduction and reducing waste.
⚙️ What is a Kanban System?
The word “Kanban” means signboard or visual card in Japanese.
In practice, a Kanban system uses cards, bins, or digital boards to signal when more material or work needs to be started.
It’s a pull-based system, meaning production happens only when required — ensuring a smooth, just-in-time flow of materials and tasks.
