23) Barry’s Tire Service completed 100 tire changes, six brake jobs, and 16 alignments in an eight-hour day
with his standard crew of six mechanics. A brake specialist costs $16 per hour, a tire changer costs $8 per
hour, and an alignment mechanic costs $14 per hour. The materials cost for a day was $2,000, and
overhead cost was $500.
a. What is the shop‘s labor productivity if the retail price for each respective service is $60, $150, and $40?
b. What is the multifactor productivity, if the crew consisted of two of each type mechanic?
24) Table 1.3
The Abco Company manufactures electrical assemblies. The current process uses 10 workers and
produces 200 units per hour. You are considering changing the process with new assembly methods that
increase output to 300 units per hour, but will require 14 workers. Particulars are as follows:
Workers are paid at a rate of $10 per hour, and overhead is charged at 140% (or 1.4 times) labor costs.
Finished switches sell for $20/unit.
a. Calculate the multifactor productivity for the current process.
b. Calculate the multifactor productivity for the new process.
c. Determine if the new process should be implemented.
