Using points and examples from the lecture, explain the two major factors of product quality and how their role in consumer decision making has changed.
1. If a consumer has to choose between two products, what determines the choice?
2. Assume that someone, a purchaser, is choosing between two products that cost the same, ok?
3. If people have a choice between two identically priced products, which one will they choose?
4. They choose the one they think is of higher quality of course, but what does mean for a product to be a high-quality product?
5. Well, business analysts usually speak of two major factors of quality.
6. One factor is reliability and the other is what we call features.
7. So, reliability.
8. What's reliability?
9. Well a product is reliable, if it works the way we expect it to work, if it can go a reasonable amount of time without needing repairs.
10. If a product, a car for example, doesn't work the way it should and needs repairs too soon, we say it's unreliable.
11. So product reliability means basically the absence of defects or problems that you aren't expecting.
12. It used to be that when people thought about product quality, they thought mainly about reliability.
13. Today it's different.
14. People do still care about reliability, don't get me wrong.
15. It's just that manufacturing standards are now so high that...we'll take cars for example today.
16. Today's cars are very reliable, so reliability is important but it iss not gonna be the deciding factor.
17. So if reliability is not the deciding factor any more, what is?
18. Features.
19. All those extras, the things a product has that aren't really necessary but that make it easier to use or that make it cool.
20. For example, new cars today are loaded with features like electric windows, sunroofs, air conditioning, stereos and so forth.
21. When people are comparing products today, they look at features, because reliability's pretty much equal across the board and that's why manufacturers include so many features in their products.
