Based on the yields attained by the subcontractor, 91% of the parts pass inspection; they will be transferred directly to the shipping department. The subcontractor did not rework the failed assemblies, but the company plans to do so and hopes that 80% can be salvaged; the remainder will be scrapped. Since the time to rework depends very much on the specific
problem, a separate rework station will be employed, and a mean time of 15 minutes
allocated for rework; the actual rework times are expected to vary greatly.
