The SMED system which stands for Single Minute Exchange of Dies, developed by Shigeo Shingo and published in his 1985 book, guides us to achieve a machine setups in under 10 minutes. The quick changeover thinking has been around for a couple of decades now but many companies still have not achieved this level of changeover. To this day, we have setups taking 60 minutes and longer. Why?
Are these long setups not viewed as a problem?
Do we just accept the status quo of long setups?
Do we even track and monitor setups?
Is it easier the just buy faster (more expensive) machines than to roll up our sleeves and figure out how to reduce our changeovers?
Is it not a priority? Are we too busy with out limited resources (yet we let go resources in the last layoff)? Short term thinking wins again?
Where’s the SMED? Can any company report that all of their setups are 10 minutes or less?
