Lean SMED system for change over setup reduction
The Standard Work Combination Sheet is the ideal Lean Tool for set up reduction.
Your goal is to minimize Cycle Time, by:
- reducing total setup time
- moving any tasks:
from "internal setup time" (happening during the normal process cycle)
to "external setup time" (happening before or after the normal process cycle)
A doctor's office visit might take a lot longer if your health care provider wasted time changing out bedsheets and restocking supplies after you arrived — rather than arranging for all of that to have been done before you ever
walked into the exam room.
Sample Quick Changeover example
This example also illustrates why we prefer to call it "quick changeover" or "setup reduction".
Would you want to go to a doctor that specializes in "single minute exchange of dies"? (SMED)
Improve ANY process
Examples of office change-overs might include:
And office change-over time can also be hidden within more subtle tasks, like:
How to use your SMED Standard Work template
for Quick Change Over Set Up Reduction
- Create your "To Be" worksheet — by copying your "As Is" worksheet — using the special utility Systems2win menu > Copy Sheet
- Redesign your work flow — looking for opportunities to:
- reduce or eliminate setup time
- move Internal Setup steps outside of the Cycle Time steps
using Shift Down and Move to move the entire row to be outside of the Cycle Time steps
(move it to a position either before or after all other steps that are within the Cycle Time)
and changing the Operator to X for External.
[You actually enter the number minus 1 (-1), which will then display as Operator "X".]
- Click the Chart All Operators button
and notice that the External Setup steps are itemized and sub-totaled, but are not charted, and are not included in the calculation of Cycle Time.
