This document introduces the BrandStarsTM and ProductPlanetsTM framework for mapping brand and product portfolios. It defines key elements used to describe brands (BrandStarTM) and products (ProductPlanetTM) within the system. These include brand attributes like BrandCore and measures of brand performance. The framework represents brands as stars and products as planets orbiting them. It can be used to evaluate how well products fit within brands and to track brand performance over time against competitors. Examples of Volkswagen and Apple brand maps are provided to illustrate how the system can be applied.
