Brand portfolios can be so messy and dysfunctional that a firm’s new product process is paralyzed because there is no concept of which brand to use on a new offering. Customers may be so confused that they can’t even buy. The brand relationship spectrum can help create clarity, leverage, and synergy in the portfolio. The idea is that a master brand may work for a new offering if its associations are consistent and helpful and will be reinforced by the new role. However, there are times in which the master brand will be inconsistent or confining and the new offering requires some separation. The spectrum suggests that a subbrand will generate some separation, an endorsed brand more, and a separate brand the most. The challenge is to find the right degree of separation and to create brands that can perform these roles.
