Case Study 2: Eastern Gear
Eastern Gear is a small manufacturing organization that makes custom gears. They
produce gears of numerous sizes, most frequently fulfilling small orders. They purchase the raw
materials once an order has been expected, and are typically able to fulfill the orders within 4
weeks. They have a relatively small leadership team, consisting of their president, a sales
manager, a head engineer, an expeditor, and a controller. The rest of their crew consists of
mostly skilled and semi skilled laborers, with about 50 employees in total.
There are a few primary problems Eastern Gear is facing. For one, it currently takes four
weeks for an order to make its way through the processing. This slow turnaround is directly
related to the constant interference of orders being processed in the shop. According to
Schroeder and Goldstein (2020), “The typical order spends 90 percent of its time waiting in line
for a machine to become available. Only 10 percent of the time is actually spent processing the
order on a machine.” This dramatic difference really slows them down, and their total order
turnaround time could be much quicker if they found a better balance. Another problem Eastern
Gear is facing is their rate of return. Although 6% of their products being returned isn’t
completely terrible, when you look one step further, it becomes alarming. Of those 6% of
shipments that are returned, 75% failed to undergo one or more critical operations. They are
returned due to the lack of something simple, like missing holes that were supposed to be drilled.
These simple mistakes should be able to be prevented easily. With that being said, these returns
slow them down and cost them quite a bit. It also makes them look bad, as their customers
