I like how you can tell they optimized the assembly line in the places where it was most necessary - not all the stations have automated screw feeders, but the overall flow of the line seems fine, so they must have put them in the places where people were previously spending too much time fishing screws out of boxes, or where screws were frequently being forgotten (thus the counter). And then at some stations they put the product on a rotating platform (lazy susan?) so that the person doing the assembly can freely rotate it 360 degrees easily without picking it up. You can tell that most of the stations didn't need it by watching how they work, but it must have been a big improvement for the stations that did.
