D. Use Piezoelectric Vibrators Instead of Mechanical Ones
E. Use Combined Ultrasonic and Electromagnetic Field Oscillations
(Use External Elements to Create Oscillation or Vibration)
• Bring new blood into the team.
• Hire a consultant.

Principle 19. Periodic Action
A. Instead of Continuous Action, Use Periodic or Pulsating Actions
• Use batch manufacturing.
• Tidal traffic flow schemes can ease transport into and out of busy
areas.
• Change team leadership periodically (e.g., countries take turns leading
the European Union).
• Introduce sabbaticals to refresh people’s points of view.

B. If an Action is Already Periodic, Change the Periodic Magnitude
or Frequency
• Audit at irregular intervals.
• Use monthly or weekly feedback instead of annual reviews.
• Use flexible savings schemes that pay higher interest rates when fewer
withdrawals are made.

C. Use Pauses Between Impulses to Perform a Different Action
• Get work done between meetings.
• Perform maintenance work during vacations.
• Provide 24-hour car service operation—evening pickup and return of
serviced car by breakfast the following morning (customer per-
spective).

Principle 20. Continuity of Useful Action
A. Carry on Work Continuously; Make All Parts of an Object Work at Full Load
All the Time
• Run the bottleneck operations in a factory continuously to reach the
optimum pace (from theory of constraints).
• Institute constant improvement (point no. 5 of Deming’s 14 points
(Deming 1982).
• Continuous on-line monitoring of elevators by Otis (total maintenance
responsibility).
