The document discusses Jean-Noel Kapferer's six element "Brand Identity Prism" model for defining a brand's identity. The six elements are: Physique (visual/tangible qualities), Personality (character), Culture (values), Relationship (with customers), Reflection (of typical customer), and Self-Image. Together these facets define a brand's identity and boundaries for developing it over time in a coherent way. The identity prism shows how the elements interconnect to form a structured whole, providing a basis for long-term branding strategy and activities.
