Furthermore, each stack has 390 of these parts. Working as a team, you want them to pick up each piece, walk up a metal ramp onto a rail car, and then neatly position and stack the parts for shipment. That’s right, you repeat – 92 pounds, walk up the ramp, and carry them onto the rail car. Anticipating their questions, you explain that a forklift could only be used if the parts were stored on a wooden pallet (they weren’t) if the pallet could withstand the weight of the metal parts (it would be crushed), and if you, as their supervisor, had forklifts and people trained to run them (you don’t).In other words, the only way to get the metal parts into the rail cars is for them to do it. Based on an old report from the last time that some of the metal was sold, you know that throughout an eight-hour shift, workers typically carried about 30 to 31 metal parts per hour up the ramp into a railroad car. At that pace, though, it will take your six college students six weeks to load all of the metal. Unfortunately, the purchasing manager who sold the stuff says you only have two weeks to get this done. So, without more workers (there’s a hiring freeze) and without forklifts, these six workers have to be loaded by hand in two weeks. But how do you do that? What would motivate them to work much harder than they have been all summer? After all, they’ve gotten used to the leisurely pace and job assignments. And while motivation might help, motivation will only get so much done. After all, short of illegal steroids, nothing will work once muscle fatigue kicks in from carrying those 92-pound parts up a ramp all day long. So, what can you change about how the work is done to deal with the physical fatigue that can’t be avoided from this kind of work?
