Every minute spent switching over is a minute of lost flow. SMED shows you which steps can happen before the stop, and how to speed up the rest. Watch the short video, then work with the toolkit PDF: it explains the method, shows a worked example and gives you a blank template to fill in.

SMED (Quick Changeover) in short
- Record a changeover. Film or time every step from last good part to first good part.
- Separate internal and external. Internal: only possible when stopped. External: possible while running.
- Move steps outside. Prepare tools, material and settings before the stop.
- Streamline the rest. Quick-release clamps, presets, parallel work, no searching.
- Standardize. Write the new changeover into an SOP and a checklist.
Key points
- Changeover time is lost capacity.
- Separate internal from external.
- Prepare while running.
- Target: under 10 minutes.
