Describe the initial columns for a new Kanban board and their purpose

Tests whether you understand Kanban as a flow visualization tool rather than a simple to-do list. A strong answer proposes four starter columns: Backlog for unprioritized ideas, To Do for committed work, In Progress for active items with a WIP limit, and Done for completed work, noting that each column represents a handoff or state change. Red flag: prescribing complex columns like Code Review or Testing before the team has mapped its actual workflow, or conflating Kanban board structure with Scrum ceremonies like sprints.
