The cost of quality is the expense of doing things wrong.
Quality means conformance to requirements, not elegance.
It is not possible to know what you need to learn.
Quality is the result of a carefully constructed cultural environment. It has to be the fabric of the organization, not part of the fabric.
If we deliver on time, but the product has defects, we have not delivered on time.
If you don't know what the defect level is, how do you know when to get mad?
