A growing educational institute is planning to change its class session structure to enhance teachers’ productivity. As per the old system, each teacher is responsible for taking five classes (each of one hour), three days a week. The number of students per class is 20.

(b) Calculate the labor productivity for the schedule change (students/hour).
(c) Are there any ethical considerations that should be accounted for?
(d) Suppose that each teacher is also required to dedicate 2 hours of office hours on the days of classes to handle students’ queries. Is the schedule change a productivity increase?

At the same time, however, an additional employee had to be hired. Under the old process, 5 employees could produce 60 pieces per hour at a cost of $16/piece of raw material. With the new process, the cost of the raw material has been reduced to $10 per piece. The direct labor cost is $12/hour per person and overhead is calculated at 1.6 times the direct labor cost. The finished products are sold at a price of $31 each.
