Kanban is a lean methodology for managing workflow. Its core practices include visualizing workflow using a kanban board with columns for different states, limiting work-in-progress to avoid bottlenecks, making policies explicit, and implementing feedback loops to continuously improve. Kanban focuses on managing flow rather than fixed processes, and emphasizes finishing work rather than starting new work. Kanban stand-ups differ from Scrum in that the focus is on identifying impediments rather than commitments.
