Stop The Line
Stop the Line is a practice in Kanban. Whenever a defect is detected downstream of the point where it should have been eliminated, the line is stopped. The team take time to identify and explore the reasons for the escape of the defect. They decide what action to take to prevent defects of the same type escaping in the future. Best practice also uses Stop the Line to identify and reinforce modified practice that brings performance benefits to the work of the team.
