Ditch Traditional Wireframes by Sergio Nouvel.
From the post:
Wireframes have played an increasingly leading role in the modern Web development process. They provide a simple way of validating user interface and layout and are cheaper and faster to produce than a final visual comp. However, most of the methods and techniques used to create them are far from being efficient, contradicting the principles and values that made wireframing useful in first place.
While this article is not about getting rid of the wireframing process itself, now is a good time for questioning and improving some of the materials and deliverables that have become de facto standards in the UX field. To make this point clear, let´s do a quick review of the types of wireframes commonly used.
Especially appropriate since I mentioned the Health Design Challenge [$50K in Prizes – Deadline 30th Nov 2012] earlier today. You are likely to be using one or more of these techniques for your entry.
Hopefully Sergio’s comments will make your usage more productive and effective!
