Kanban boards show how work moves from left to right, each column represents a stage of the overall process, or to be more precise the system that is visualised by the board. The team pulls cards from one column to another to the right to show progress, and to coordinate their efforts with others.
At its simplest, boards are usually divided into "waiting", "work in progress" and "completed work". Complex Kanban boards can be created that visualise the flow of work across a whole value stream map.
