SINGLE MINUTE EXCHANGE OF DIE (SMED)

Single Minute Exchange of Die (SMED) is a Lean methodology created by Shigeo Shingo to drastically reduce equipment changeover or setup time. Originally used in manufacturing, SMED separates activities into two types:

  • Internal activities: Tasks done while equipment is stopped

  • External activities: Tasks that can be done while the equipment is still running

By converting internal steps into external ones, teams minimize downtime and keep workflows moving.

It’s all about making the workflow unobstructed.

When Can You Use SMED in Construction?

In the construction industry, Single Minute Exchange of Die (SMED) helps reduce delays and optimize productivity. For instance, quick couplers—used on excavators—allow for fast attachment changes without manual tools, keeping projects on schedule.

What is the Goal of SMED?

The goal of Single Minute Exchange of Die (SMED) is simple: reduce setup time to keep both equipment and crews moving. While the name implies setups under 10 minutes, the deeper aim is continuous improvement.

Originally, SMED cut press setup times from over an hour to just minutes. In construction, similar improvements lead to faster project delivery, fewer delays, and higher productivity.
