Many work center operations will have time required for setup and teardown times outside of the time consumed by actually producing the product. This is certainly true for our example. It takes time for someone to prepare a printing press with inks before the first T-shirt can be printed. For our example, we have estimated five minutes of setup time. Likewise, when we are done producing the last product in our work order, it takes time to clean up and prepare for the next job. In this example, we have estimated five minutes of time at the end of production for cleanup operations.
