Exercise 14-34 Name:
Insert your answers into the gray-shaded cells. If an answer is incorrect, the
word “wrong” will appear.
a. ÷ Total time = MCE
25,000 61%
b. Process
productivity
15,160 6.89 units per hour
c. Process
quality yield
104,500 94.16%
d. ÷ Total time = Throughput
25,000 3.94 units per hour
e.
104,500
Discuss whether throughput is as useful a performance measurement in a job shop
as in an automated plant. Why would you expect process quality yield to be high in a
job shop? Why might a job shop such as Durham Divisions have low manufacturing
cycle efficiency?
Throughput would be useful in a job shop because most jobs are typically taken with
customer agreements as to quality of production/service and time of delivery.
Calculation of throughput would provide useful information for future contracts.
There would be an expectation of high process quality yield in a job shop because
employees are more likely to be directly engaged in the production/service process
and, thus, able to spot and correct defects as they occur.
move distance between operations or idle time.
