CORE DEFINITION

By converting internal operations (which require stopping the machine) into external operations (which can be prepared while the machine is running), reduce machine changeover time from hours to minutes (single-digit minutes).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Enhance agility. If switching tasks (Context Switch) takes a long time (e.g., 30 minutes of preparation before a meeting), your efficiency is extremely low. Through SMED thinking, optimize your workflow to make the 'switching cost' approach zero.

SMED (Single-Minute Exchange of Die): Compress equipment changeover time to single-digit minutes. The core is to convert internal operations (requiring shutdown) into external operations (which can be prepared in advance), thereby reducing downtime and enhancing flexibility.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.
