Improving quality requires a culture change, not just a new diet.
In a true zero-defects approach, there are no unimportant items.
Many managers feel, somewhat cynically, that people are being paid to do their jobs and that's that. This attitude reflects an insensitivity to people that is a trademark of many hockey-style managers.
Quality has to be caused, not controlled.
When you're out of quality, you're out of business.
If anything is certain, it is that change is certain. The world we are planning for today will not exist in this form tomorrow.
