Kanban is a method to visualize and manage work by moving tasks through stages on a board. Tasks start in the To Do column, then move to In Progress when work begins, and finally to Done when completed. This flow helps teams see progress and avoid too many tasks being worked on at once. The execution table shows a task created, moved through stages, and reviewed. Variables track where tasks are at each step. Key moments clarify why tasks move stepwise and the importance of limiting work in progress. The quiz tests understanding of task status at different steps and how adding tasks affects the board.
