SMED where you wouldn’t imagine: magic tricks

Cloths. SMED where you wouldn't imagine: magic tricks. Change Management

Single Minute Exchange of Die (SMED) is one of the lean methodologies developed initially by Shigeo Shingo in Japan to increase productivity by decreasing downtimes during change of tools.

For big factory toolings, this is in reality usually still more than one minute although this approach has decreased it by hours if not days.

But in this example, you will even see it opposite … many times per minute! Watch closely and see some common approaches.

– see video below –

Among other SMED techniques, you’ll recognize:

 Traditional SMED techniques… applied here, among others
 Prepare tools in advance
  • clearly, in some cases, she has already several dresses one on top of the other
  • different “bags”, already on the floor, each with its parts

 Adapt the tools for the rapid change also, not only for the run

(in other parts of this site, this would be similar to “adapt the product to all its life phases”)

  • hook-and-loop fasteners (velcro) techniques
  • ultra thin clothes, from largest to smallest (at the beginning)
  • double side dresses, each with a different color
Do tasks in parallelWatch the partner … he is not just holding the screen or performing some miss-direction
Improve ergonomicsPosition preparation (watch the hands position for the last one, the most impressive, just before the “magic”)
Universoul circus: quick change

The biggest difference with Industrial application being that in this magic the focus is at the external operations (the changes) while in production, the value added being the internal operations, the rest being wastes.

Glossary of Terms Used

Single Minute Exchange of Dies (SMED): a lean manufacturing technique aimed at reducing equipment setup times to less than ten minutes, enabling quicker transitions between production runs and increasing overall efficiency by streamlining processes and minimizing downtime.

      Interesting take on SMED in magic tricks! But isnt the whole point of magic the mystery, not efficiency?

    2. Kathryn

      Interesting read! But arent there some magic tricks where SMED isnt applicable? Not all can be quick change, right?
