The plant was designed to run 1,000 boards per day when running five days a week and one eight-hour
shift per day. Unfortunately, to date, it has not come near that capacity, and on a good day it is able to
produce only about 700 boards. Data concerning the standard setup and run times for the fabrication
process are given in Exhibit 7.8. These times include allowances for morning and afternoon breaks, but
do not include time for the half-hour lunch period. In addition, data on current staffing levels also are
provided. The CBF process engineer insists that the capacity at each process is sufficient to run 1,000
boards per day.
In order to understand the problem, CBF hired you to help determine why it is not able to produce the
1,000 boards per day.
