A medical equipment testing and calibration service is depicted in Figure 1. The
customer usually brings the equipment to the service center. The service process
requires service technicians to perform three process steps #1 to #3. Each technician is
cross-trained so they can perform any of the three steps. The inspector does Step # 4
alone. After step #4, two parallel work activities are performed. That is, a shipping clerk
packs the work (step 7) while a billing clerk prepares the invoice (step 5)
simultaneously, and the customer is contacted by phone for pick-up (step 6). The
average throughput is 3 equipment units per hour.
