Problem 1: Compare the effort needed for the six levels of quality of an automobile to a toothbrush OR SOME OTHER SIMPLE ITEM. You can choose running shoes, ink pen, sun glasses, or any relatively simple product.
Problem 2: Obviously the automobile requires a lot of effort due to the large number of components and interrelationships between them, while a toothbrush (or your item) is pretty simple. Yet both of them require all six quality levels to assure a quality product (as do all products).
Problem 3: Compare each quality level and the effort needed for the automobile and the simple item you choose. Write at least two pages discussing these comparisons (similarities and differences).
