Tips on Prototyping for Usability Testing
Don’t let prototyping drive your design. The best prototyping tools are not necessarily the best design tools. It certainly saves time if you can design and prototype at the same time, but the last thing you should have to focus on when designing are the limitations of a prototyping tool. If you find that you’re spending more time trying to figure out how to make something work in the prototype than on your design, you should take a step back and focus on the design, then later, try to figure out how to prototype it.
