Concerning fidelity in design

People swear by their design processes. Rachel Glaves insists on sketching by hand; Dan Brown urges extensive wireframing; while Ryan Singer goes straight to HTML. Heated debates arise at conferences as advocates staunchly defend their favorite techniques.

With all of these different methods to choose from, should you be sketching, wireframing, mocking-up, or prototyping? The answer, simply put, is yes you should.

Design methods are not mutually exclusive. Rather, each method exists on a continuum of fidelity, ranging from low fidelity sketches to high fidelity HTML prototypes. Each method is well-suited for a particular phase of the design process, with one level of fidelity often leading into the next.
