Fancy prototyping and wireframing software comes and goes but sketching is still the ultimate design communication tool.
Some tips for low fidelity wireframing:
Start rough and refine.
Use a whiteboard, flip charts or big sheets of cheap paper. Get all your ideas out of your brain and onto a medium that allows other people to see where you’re going.
Don’t erase, iterate.
An effective way of communicating your design is to explain the journey you took, the different ideas you explored and the rationale behind your decisions. This is difficult to do if you only record your final designs and not the steps that you took to get there.
Don’t be precious.
Your first idea is not always the best one – record them, but be ready to abandon ideas that are going nowhere and go back to the drawing board.
Annotate everything.
Sure, you understand what that squiggly line is and what that obscure symbol represents, but will they make sense to your coworkers (or your future self for that matter)? Adding neat, numbered annotations to your paper wireframes allows you to include notes on important features and functionality. Include these annotations in a different (consistent) colour so that it’s clear they are not part of the design.
