Question 3

In an assembly operation at a computer factory, nine employees assembled an average of 540 custom computers per 5-day week. What is the labor productivity of this operation?
A) 75 computers per worker per day
B) 50 computers per worker per day
C) 12 computers per worker per day
D) 108 computers per worker per day

Accepted Answer

The labor productivity is calculated by dividing the total output by the total input. Here, the total output is 540 computers per week, and the total input is 9 employees working for 5 days. So, the productivity per worker per day is (540 computers / 9 workers) / 5 days = 12 computers per worker per day.

Question 4

A process produces 2,500 units of output that sell for $10 per unit. Resources contributed to this output are 100 hours of labor at $20 per hour, materials at $300, and overhead at $700. What is the labor productivity?
A) 20 units per hour
B) 25 units per hour
C) 40 units per hour
D) 30 units per hour

Accepted Answer

Labor productivity is calculated by dividing the total units produced by the total labor hours. In this case, total units produced are 2,500 and total labor hours are 100. So, labor productivity is:
2,500 units / 100 hours = 25 units per hour
Therefore, the correct answer is B.

Which of the following would be considered an advantage to a firm using a global supply chain?
A) highly skilled but expensive foreign workers
B) cheap but untrained foreign workers
C) cheap sources of raw materials from a politically corrupt country
D) highly reliable suppliers

Accepted Answer

Highly reliable suppliers are a major advantage for a firm using a global supply chain. With dependable suppliers, a firm can ensure consistency in the quality of their products and minimize disruptions in their production process. Highly skilled foreign workers may also be an advantage, but the cost factor may be a disadvantage. Cheap but untrained workers and cheap raw materials from politically corrupt countries may lead to quality and ethical issues, which can be a disadvantage for the firm in the long run.

Question 15

Lean operations does not include which of the following practices?
A) improving quality
B) reducing bottlenecks
C) redesigning complex pathways
D) reducing the number of reliable suppliers

Accepted Answer

Lean operations focuses on eliminating waste and improving efficiency in order to create value for the customer.

Therefore, reducing the number of reliable suppliers is not a practice included in Lean operations.
