Management's job is to optimize the whole system.

The greatest waste … is failure to use the abilities of people…to learn about their frustrations and about the contributions that they are eager to make.

The aim of leadership should be to improve the performance of man and machine, to improve quality, to increase output, and simultaneously to bring pride of workmanship to people. Put in a negative way, the aim of leadership is not merely to find and record failures of men, but to remove the causes of failure: to help people to do a better job with less effort.

People need to know what their jobs are.

Everyone is a customer for somebody, or a supplier to somebody.

The prevailing style of management must undergo transformation. A system can not understand itself. The transformation requires a view from outside.

When a worker has reached a stable state, further training will not help him.
