Andon board: a visual control device in a production area,
such as a lighted overhead display. It communicates the current status of the
production system and alerts team members to emerging problems.
Balancing the line: the process of evenly distributing both the
quantity and variety of work across available work time, avoiding overburden and
underuse of resources. This eliminates bottlenecks and downtime, which
translates into shorter flow time.
