What is the difference between SMED and quick changeover?

SMED is a specific methodology with defined steps (separate internal/external, convert internal to external, streamline). Quick changeover is the general goal. SMED is the most widely used framework for achieving quick changeovers.

Can Yamazo Studio track SMED improvements over time?

Yes. Yamazo Studio has a dedicated SMED track type that lets you tag activities as internal or external. You can record multiple changeover rounds and compare the timelines to measure improvement.

How does video analysis improve SMED implementation?

Video provides objective, frame-accurate data instead of estimates. Engineers can review activities in slow motion, identify waste that is invisible at normal speed, and create evidence-based standard work for the optimized changeover process.

Glossary

SMED (Single Minute Exchange of Die) | Lean Manufacturing Glossary

SMED (Single Minute Exchange of Die) is a lean manufacturing methodology aimed at reducing equipment changeover time to under 10 minutes. Developed by Shigeo Shingo at Toyota, SMED systematically converts internal setup activities (performed while the machine is stopped) into external activities (performed while the machine is running).

How to Create

To implement SMED with Yamazo Studio: Record the entire changeover process on video. Tag each activity as internal or external using the dedicated SMED track type. Analyze the timeline to identify activities that can be converted from internal to external. Implement improvements and record the new process to measure reduction. Track progress over multiple rounds of optimization.

Example

A plastic injection molding facility recorded a 45-minute die changeover. Using Yamazo Studio's SMED analysis, they identified 18 minutes of activities that could be performed externally (pre-staging tools, pre-heating dies). After implementing changes and re-recording, changeover time dropped to 12 minutes — a 73% reduction.
