Long-term commitment to new learning and new philosophy is required of any management that seeks transformation. The timid and the fainthearted, and the people that expect quick results, are doomed to disappointment.

You have to manage a system. The system doesn't manage itself.

Without theory there is nothing to modify or learn.

What makes a scientist great is the care that he takes in telling you what is wrong with his results, so that you will not misuse them.

You must have a supplier relationship of constant improvement.

Management does not know what a system is.

When people try to do what they can not do, they wish to give up.
