A Kanban board is a visual tool used in project management to help teams organize and track their work. It typically consists of columns representing different stages of a process, such as "To Do," "In Progress," and "Done." Tasks are represented by cards that move across the board as they progress through these stages, allowing team members to see the status of work at a glance. Originally developed in the manufacturing sector by Toyota, the Kanban method emphasizes continuous improvement and efficiency. By visualizing tasks and limiting work in progress, teams can identify bottlenecks and optimize their workflow, leading to better productivity and collaboration.
