What do columns represent on a Kanban board?

On a Kanban board, columns represent a workflow that cards move across, illustrating the various stages of work in the completion process. Each column typically corresponds to a specific step in the workflow, such as "To Do," "In Progress," and "Done." This visual representation allows team members to see the status of tasks at a glance and understand how work is progressing through the system. The movement of cards from one column to another indicates the status change of tasks as they are worked on and completed, facilitating better tracking and management of work in progress. This structure supports the principles of Kanban, emphasizing continuous delivery and flow improvement by limiting work in progress and enabling teams to identify bottlenecks effectively.
