Brand architecture is the structure of brands within an organizational entity. It is the way in which the brands within a company’s portfolio are related to, and differentiated from, one another. The architecture should define the different leagues of branding within the organization; how the corporate brand and sub-brands relate to and support each other; and how the sub-brands reflect or reinforce the core purpose of the corporate brand to which they belong. Often, decisions about Brand Architecture are concerned with how to manage a parent brand, and a family of sub-brands - Managing brand architecture to maximize shareholder value can often include using brand valuation model techniques.
