Shiny Wheel, Shiny Car?

It would seem silly to spend Saturday morning cleaning and polishing one wheel of your car, wouldn't it? In fact, it would look funny driving down the road with a dirty, muddy car, except for one, sparkling clean wheel.
If you look around, you’ll notice shiny wheels everywhere. In other words, suboptimal. So, suboptimal is when someone focuses on one part of a system and ignores the whole. It happens all the time. We find it at home, in our personal lives, and at work.
