Product design follows a five-layer model from abstract strategy to concrete visuals. Each layer builds systematically upon the previous one, creating a comprehensive user experience framework.
The Strategy Layer forms the foundation of product design. It balances user needs with business objectives. Users want to solve specific problems, while companies have goals like profit and growth. This layer ensures both perspectives align to create meaningful products.
The Scope Layer defines what features and content the product will include. The Structure Layer organizes how these elements connect and flow together. Scope answers 'what to build' while Structure answers 'how to organize it'.
The Skeleton Layer creates the interface blueprint or wireframe. It defines where buttons, navigation, content areas, and interactive elements are positioned. This layer focuses on layout and hierarchy without visual styling.
The Surface Layer is where visual design comes alive. Colors, typography, images, and brand elements create the final user experience. This layer transforms wireframes into beautiful, engaging interfaces that users see and interact with daily.
