What is one reason that a brand may not want to get rid of a product that isnt meeting goals?

The only reason a company doesn't want to get rid of a product which is not paying off or meeting goals is, that product is the face of the company. And if the company wants to get rid of that, it will lose its base.

Suppose if KFC removes zinger burger from its product line, it will lose its base popularity. Even though if Zinger is not bought by much people, KFC cannot stop its production. Because this is actually the face of KFC.

Hello how are you? ...
