What SMED Measures
SMED reduces changeover downtime by separating internal work that must happen while stopped from external work that can happen while running.

What is SMED?
SMED, or Single-Minute Exchange of Die, is a lean method for reducing changeover time. It separates internal setup work that requires stopped equipment from external setup work that can be prepared while the process is still running.
Use this calculator to estimate the impact of a proposed setup reduction. If changeovers are limiting capacity, combine the result with the OEE Calculator and Process Capacity Sheet to quantify the broader throughput impact.
