1. Prototyping allows for strategic and tactical user experience design by developing visions and business strategies top-down while delivering strategies bottom-up through quick execution. 2. An effective process involves assembling a multidisciplinary team, sketching prototypes in HTML instead of Photoshop, testing real content in multiple iterative prototypes, and only documenting what is necessary. 3. Prototyping beats abstract planning and documentation by making new ideas less scary through showing rather than telling, embracing experimentation, and making evidence-based decisions with stakeholders.
