In the circus world, tightrope walking requires incredible balance and finesse. One wrong move can have dire consequences. Optimizing workflow on an assembly line is not as dangerous, but it requires a similar set of skills.

Automotive assembly lines have operated the same way for a century. Each worker takes charge of a single process and installs parts in vehicles as they move on a chain-driven or skillet conveyor.

Color affects mood and perception. It’s amazing how a slight change in color can alter the look and feel of a room. I found this out first-hand recently after doing a little painting at home. Whenever I step into an assembly plant, I always try to take a quick look at the color of its floor, walls and equipment. Usually, it’s nothing to get too excited about.
