The Toyota Problem-Solving Mindset:

    OBSERVE (Genchi Genbutsu)
           ↓
    DEFINE (Current Condition)
           ↓
    ANALYZE (Root Cause - 5 Whys)
           ↓
    COUNTERMEASURE (Experiment)
           ↓
    STANDARDIZE (If effective)
           ↓
    SHARE (Yokoten - horizontal deployment)

The Three MUs (無駄・無理・斑):
