Quality of Life

I'm on a crusade. A crusade for better quality of life. In fact, a crusade for quality that means life. A lot of money is wasted. People are being injured, sometimes seriously, or even being killed because of poor quality software. We have the power to help put an end to it. If you have read any of my previous posts, you may have noticed a recurring theme: software quality. Even if the post wasn't about that at all, it seemed to always crop up. And that is what my crusade is about. I need your help.
