Firstly, why prototype a website? For the same reason builders have blueprints, financiers use models and movie-makers pen screenplays and leverage pre-visualization. After the definition phase comes the design phase. Thoughtful design can save time, money, and head space for production crews. When it comes time to start shooting a movie, filmmakers would rather concentrate on creating the vision and not break stride by having to rewrite lines and scenes. One responsibility of web design is to answer as many questions as possible prior to the development phase. It’s a lot easier to alter a design than it is revamp an entire wing of a half-constructed house.Let’s prototype!
