But the world did change, and Detroit is still dead last in the quality sweepstakes. The world changes, and it does not change all by itself. Everything we do changes it. In another lesson from physics, Heisenberg showed that you can know a particle s location or its velocity but not both. When you measure one, you change the other.
People are just like that.
As soon as you fix the process, the problem changes. We must keep thinking, and resist the temptation to blindly rely on the solutions and formulas of the past. Continue to follow the same principles, certainly, but don t blindly follow the same path. Sooner or later it will lead to a dead end. While process problems are often unique, they all stem from human failings, and these are common to all of us.
