What is compensatory method?

I learned in my marketing class that the compensatory method is when you allocate 100 points for a different features of a product and then you give the feature that is most important to you the most points. It is a method that is used to help a consumer make a decision about a product.

Here's an example: If you were going to buy a TV, the different features of a TV would be its size, screen quality, wi-fi connection. If the screen size was most important to you, you would give that category 50 out of the 100 points. If screen quality was next in importance to you, you would give it a 30 out of the 100 points. If wi-fi connection was least important to you, you would give it the least amount of points. In this case you would give it a 20 out of the 100 points. Thus, 50+30+20=100 points. Now, when you are shopping for your tv you can rank each tv you are considering and the one that is closest to the points you allocated in each category is ultimately the one you should buy.

*this is a very subjective method- the product that you are "suppose" to buy after completing this method may not be the product that you actually want. This method can also make you realize what features/categories are most important to you when making a big decision
