a. In this example, I would imagine the layout of a producing facility to be very efficient. It would be divided into different stations that would each be dedicated to a particular task.
b. The way in which someone would know that they were done working on this product is that the manufacturers would be trained to recognize the details and the specific characteristics that show high quality in a product.
c. The product I selected is high-end shoes. The way in which efficiency would be calculated in this case would be by paying attention to the number of people who are working on a product, the time they take to produce it, and the final number of products we have.
d. I do not believe that there are other ways to make this product that would result in more efficiency. However, it is possible to produce the product in a less efficient way, such as using a cobbler who makes every pair by hand.
