"All changes, even positive ones, are scary. Attempts to reach goals through radical or revolutionary means often fail because they heighten fear. But the small steps of kaizen disarm the brain's fear response, stimulating rational thought and creative play."

Previous Quote

If you are going to do kaizen continuouslyyou've got to assume that things are a mess. Too many people just assume that things are all right the way they are.   Aren't you guys convinced that the way you're doing things is the right way? That's no way to get anything done. Kaizen is about changing the way things are.   If you assume that things are all right the way they are, you can't do kaizen. So change something!
