It is also called breakthrough kaizen and is contrasted with gradual, step-by-step kaizen. Examples include relocating equipment over a weekend to create single-piece flow in a compact cell, or switching a large product such as a commercial airliner from stationary to moving assembly.","study_notes":["Sometimes called kakushin.","Also called breakthrough kaizen, in comparison with more gradual, step-by-step kaizen.","Example: moving equipment over a weekend so products formerly fabricated and assembled in batches in isolated process villages are made in single-piece flow in a compact cell.","Example: quickly switching from stationary to moving assembly for a large product such as a commercial airliner.","The document cross-references PDCA and process village."],"safety_notes":[],"sources":[{"url":"https://www.lean.org/lexicon-terms/kaikaku/","title":"Kaikaku - Lean Enterprise Institute","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":1,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"operational","spec":{"kind":"methodology","related":["kaizen"]},"url":"https://machineschema.com/operational/kaikaku","license":"https://creativecommons.org/licenses/by/4.0/"}
