1. Two machines are used to put packets on shelves in the warehouse; one can place
1000 packets in 30 minutes, while the second can put 900 packets in 20 minutes.
Which machine is more productive?
Answer:
Productivity of machine 1 = 1000 packets/30 minutes
= 33.3 packets per minute
Productivity of machine 2 = 900 packets/20 minutes
= 450 packets per minute
Machine 2 is more productive.

2. A worker typically completes packing 30 packs in a day. However, currently, the
worker completes 80 packs in three days. Did the workers’ productivity improve?
Answer:
Productivity in worker before = 30 packs / 1 day = 30 packs per day
Productivity in worker after = 80 packs / 3 days = 26.7 houses per day
The workers productivity decreased.

3. One painter can paint 200 square feet of wall in three hours. The second painter
can paint 150 square feet of wall in two hours. Which painter is more productive?
Answer:
For the first painter: 2 square feet in 3 hours = 200/3 = 66.67 approx square feet
per hour.
For the second painter: 150 square feet in 2 hours = 150/2= 75 square feet per
hour.
Comparing the two rates: First painter: ~66.67 square feet/hour and Second
painter: 75 square feet/hour
The second painter is more productive, painting 75 square feet per hour compared
to the first painter's approximately 66.67 square feet per hour.

4. A firm makes dining chairs in Units 1 and 2. At Unit 1, five workers produced 250
chairs. At Unit 2, six workers produced 280 chairs during the same time period.
Which facility was more productive?
Answer:
Productivity at unit #1 = 250 chairs / 5 workers = 50 chairs per worker
Productivity at unit #2 = 280 chairs / 6 workers = 46.7 chairs per worker
Unit #1 was more productive.

5. A painter is considering using a new high-tech paint roller. Yesterday he was able
to paint three walls in 45 minutes using his current roller. Today he painted two
walls of the same size in 20 minutes. Is the painter more productive using the new
paint roller?
Answer:
Productivity using old method = 3 walls / 45 minutes = 0.07 walls per minute
Productivity using new method = 2 walls / 20 minutes = 0.10 walls per minute
The painter is more productive using the new paint roller.

6. Aztec Furnishings makes hand-crafted furniture for sale in its retail stores. The
furniture maker has recently installed a new assembly process, including a new
sander and polisher. With this new system, production has increased to 95 pieces
of furniture per day from the previous 55 pieces of furniture per day. The number
of defective items produced has dropped from 8 pieces per day to 2 per day. The
production facility operates strictly eight hours per day. Evaluate the change in
productivity for Aztec using the new assembly process.
Answer:
Using only the non-defective production, productivity has increased from (55 – 8)
= 47 pieces per day to (95 – 2) = 93 pieces per day.
Change in productivity = (93 – 47)/47 × 100% = 97.9%
There is a 97.9% increase in productivity using the new assembly process.

7. Howard Plastics produces plastic containers for use in the food packaging
industry. Last year its average monthly production included 20,000 containers
produced using one shift five days a week with an eight-hour-a-day operation. Of
the items produced 15 percent were deemed defective. Recently, Howard Plastics
has implemented new production methods and a new quality improvement
program. Its monthly production has increased to 25,000 containers with 9 percent
defective.
a) Compute productivity ratios for the old and new production system.
b) Compare the changes in productivity between the two production systems.
Answer:
a) Using only the nondetective production, productivity increased from (20,000 ×
0.85) = 17,000 units/month to (25,000 × 0.91) = 22,750 units/month.
b) Change in productivity = (22,750 – 17,000)/17,000 × 100% = 33.8%
There is a 33.8% increase in productivity using the new production method.

8. Med-Tech labs is a facility that provides medical tests and evaluations for
patients, ranging from analyzing blood samples to performing magnetic resonance
imaging (MRI). Average price to patients is $85 per patient. Labor costs average
$18 per patient, materials costs are $22 per patient, and overhead costs are
averaged at $20 per patient.
a) What is the multifactor productivity ratio for Med-Tech? What does your
finding mean?
b) If the average lab worker spends four hours for each patient, what is the labor
productivity ratio?
Answer:
a) Multifactor productivity = $85/($18 + $22 + $20) = 1.42
This means that the lab is charging approximately 42% over the expenses of
labor, materials, and overhead.
b) Labor productivity = $85/4 hours = $21.25 per hour
