Producing and moving one item at a time (or a small and consistent batch of items) through a series of processing steps as continuously as possible, with each step making just what is requested by the next step.
Flow production

Push system : material is pushed into downstream workstations regardless of whether resources are available.
Pull system: material is pulled to a workstation just as it is needed.

• The Andon board is a simple but highly-visible electronic sign displaying the status of production lines.
• It notifies management immediately if a worker has identified a fault, precisely identifying its location.
• The production line will not be restarted until the reason for the fault has been resolved.
