Kanban Board
A Kanban board is a visual project management tool that displays work progress across different stages using cards representing tasks and columns representing process stages. Originating from Japanese lean manufacturing principles and the Kanban work management system, it has become widely adopted across knowledge work and software development. The Project Management Institute defines it as “a visualization tool that shows work in progress to help identify bottlenecks and overcommitments, thereby allowing the team to optimize the workflow.” Basic boards use three columns—“to-do,” “in progress,” and “done”—with cards moving left to right to show advancement. Modern digital implementations include Jira, Asana, Trello, Monday.com, and Notion.
