Learning is not compulsory... neither is survival.

~ W. Edwards Deming

Profit in business comes from repeat customers, customers that boast about your project or service, and that bring friends with them.

~ W. Edwards Deming

The prevailing - and foolish - attitude is that a good manager can be a good manager anywhere, with no special knowledge of the production process he's managing. A man with a financial background may know nothing about manufacturing shoes or cars, but he's put in charge anyway.

~ W. Edwards Deming

Quality is everyone's responsibility.
