Kaikaku in the Lean Lexicon ©

Kaikaku

Radical, revolutionary improvement of a value stream to quickly create more value with less waste; sometimes called kakushin.

One example would be moving equipment over a weekend so that products formerly fabricated and assembled in batches in isolated process villages are made in single-piece flow in a compact cell. Another example would be quickly switching from stationary to moving assembly for a large product such as a commercial airliner. Also called breakthrough kaizen, in comparison with more gradual, step-by-step kaizen.
