What is SMED?
SMED (Single-Minute Exchange of Dies) is a lean method for slashing changeover time — the time a machine or line is stopped between products. The core move is converting internal setup (done while stopped) into external setup (done while running), then streamlining what remains. Shorter changeovers enable smaller batches, more flexibility and higher availability.
How to use the calculator
- 1
Measure current setup time
Enter the changeover time you observe today. A frame-accurate video study captures every internal and external step.
- 2
Set a realistic target
Enter the setup time after converting internal steps to external and streamlining the rest.
- 3
Read the annual value
The tool multiplies the saving per changeover by frequency, work days and hourly value.
Frequently asked questions
What is internal vs external setup?
Internal setup must be done while the machine is stopped; external setup can be done while it is still running. The first SMED win is moving as much as possible from internal to external.
Is the annual value guaranteed?
No — it is an estimate based on the value per hour you enter. Real gains depend on how freed capacity is used and on changeover frequency. Treat it as a prioritisation figure.
How does Yamazo Studio help with SMED?
Yamazo Studio's SMED track breaks a changeover into internal/external steps from video, quantifies each, and flags what can move external — so your target time is grounded in evidence.
