The document discusses various methods and tools for designing systems and prototypes quickly, including: 1. Agile and lean methodologies that emphasize iterative design, minimum viable products, and customer feedback. 2. Design sprints, which are 5-day events to solve problems through research, solution generation, prototyping, and user testing. 3. The importance of design systems to create reusable components and quickly build high-fidelity prototypes. 4. Different types of design and prototyping tools that can help implement the above methods, including graphic tools, prototyping tools, and tools to record user testing sessions.
