20 Continuity of useful action

Carry on work continuously; make all prts of an object work at full load, all the time.
  • Escalator running continuously, carrying passengers without interruption.
  • Flywheel (or hydraulic system) stores energy when a vehicle stops, so the motor can keep running at optimum power.
  • Run the bottleneck operations in a factory continuously, to reach the optimum pace. (From theory of constraints, or takt time operations)

Eliminate all idle or intermittent actions or work.
  • Print during the return of a printer carriage--dot matrix printer, daisy wheel printers, inkjet printers.
Principe 20 : Escalator running continuously, carrying passengers without interruption.
