Kanban is a visual project management tool used to manage work as it moves through a process. A Kanban board visualizes work, limits work-in-progress, and maximizes efficiency. It identifies potential bottlenecks. Common Kanban cards include withdrawal, supplier, emergency, and production cards. The six Kanban practices are to visualize the process, control work in progress, manage flow, communicate policies, implement feedback, and collaborate for improvement. Kanban offers advantages like versatility, continuous improvement, responsiveness, higher output, and team empowerment. Disadvantages include potential for Kanban board misuse and unsuitability for dynamic projects.
