Prototyping is a big deal right now. We get wrapped up in mailing list threads, new tools are released at an astonishing pace, books are being published, and articles show up on Boxes & Arrows. Clients are even asking for prototypes. But here’s the thing… prototyping is not a silver bullet.
There is no one right way to do it.
However, prototyping is a high silver content bullet. When aimed well, a prototype can answer design questions and communicate design ideas. In this article, I talk about the dimensions of prototype fidelity and how you can use them to choose the most effective prototyping method for the questions you need answered.
The dimensions of fidelity
A prototype’s fidelity has the most influence over its effectiveness. Fidelity simply refers to how realistic the prototype is. Most of the time when we talk about a “high-fidelity” prototype we are referring to a prototype that has some visual or industrial design applied to it. But that leaves out what’s most important to UX designers, what it’s like to actually work with the prototype!
Fidelity is multidimensional.
Not only can you have a prototype that looks like a realistic product, but you can also have a prototype that works like a realistic product. I call these dimensions of fidelity “visual fidelity” and “functional fidelity.” By varying your prototyping methodology along these two dimensions you can ensure that your prototyping effort is successful given your particular context. Let’s take a look at some examples.
