How to do SMED?

To reduce the red marked time span, internal and external change-over has to be separated first and eliminated after.

What means separation of internal and external processes?
  • Sketch the current changeover process on a timeline
  • Mark all processes which must stay internal for now
  • Mark those processes which could be switched to external processes
  • External processes have to be performed before the actual changeover starts
  • Perform kaizen activities to improve the remaining internal processes
