Kanban is a visual workflow management method that helps teams optimize their work processes. Originating from Toyota's production system, it emphasizes continuous delivery and efficiency by visualizing tasks on a board, allowing team members to see the status of work at a glance. The core principle of Kanban is to limit work in progress (WIP), which helps to identify bottlenecks and improve overall productivity. By using cards to represent tasks and columns to indicate different stages of the workflow, teams can manage their workload more effectively and adapt to changing priorities.
