5 examples of kaizen

  1. The Toyota line

    Workers suggest small fixes daily; thousands of tiny tweaks add up to world-class quality.

  2. The two-minute habit

    Starting with 'just read one page' is sustainable in a way 'read an hour' never is.

  3. British cycling marginal gains

    Improving dozens of 1% details — pillows, hand-washing, tyre — turned a mediocre team into Olympic champions.

  4. The slow declutter

    One drawer a day beats waiting for the perfect free weekend that never comes.

  5. Code refactoring

    Leaving each file a little cleaner than you found it keeps a codebase healthy without a giant rewrite.
