Brand evaluation is describes the value of having a well-known brand name, based on the idea that the owner of a well-known brand name can generate more money from products with that brand name than from products with a less well known name, as consumers believe that a product with a well-known name is better than products with less well-known names.
Brand management is the analysis and planning on how that brand is perceived in the market. Developing a good relationship with the target market is essential for brand management. Tangible elements of brand management include the product itself; look, price, the packaging, etc. The intangible elements are the experience that the consumer has had with the brand, and also the relationship that they have with that brand. A brand manager would oversee all of these things.
