To cope with these pressures and complexities, brand managers have had to create and manage brand teams that are often intricate and complex, involving multiple brands, aggressive brand extensions, and complex structures involving subbrands and endorsed brands. This set of challenges has created a new discipline that can be labeled "brand architecture" because it deals with relationships and structures not unlike those facing an architect who must design the structure and layout of rooms, buildings, and cities. A coherent brand architec- ture can lead to impact, clarity, synergy, and leverage rather than market weak- ness, confusion, waste, and missed opportunities.
