A comprehensive infographic comparing three design thinking frameworks: the Double Diamond Model, the User-Centered Design (UCD) Process, and the Lean UX Process. It details the stages, inputs, activities, outputs, and key principles for each, including illustrations of people, a map of Latin America, and a conveyor belt system for Lean UX.

Each of these frameworks—the Double Diamond model, UCD process, and Lean UX process—offers unique advantages. The Double Diamond excels in providing a structured approach to complex problems, UCD ensures user-centricity, and Lean UX fosters rapid experimentation and delivery. By understanding these methodologies, UX teams can choose the one that best aligns with their project goals and constraints.
