Prototyping

The document discusses prototyping and its role in the design process. It notes that prototyping allows designers to explore, understand, and communicate ideas through models of varying levels of fidelity, from low-fidelity paper prototypes to higher fidelity interactive prototypes. Prototypes evolve through iterative cycles from disposable to reusable as understanding improves. The document emphasizes that prototyping is a critical part of transforming ideas into validated solutions.
