What is a Kanban board and how does it differ from Scrum?

A Kanban board is a visual management tool that displays work items as cards moving through columns representing workflow stages, typically "To Do," "In Progress," and "Done." Unlike Scrum, Kanban does not use fixed-length sprints or prescribed roles. Work flows continuously with a focus on limiting work in progress, or WIP limits, in each column to prevent bottlenecks. Scrum delivers in timeboxed iterations with defined ceremonies, while Kanban emphasizes continuous flow and throughput. ---
