Word:  Mobile-First

Definition: The practice of designing for the smallest screen first  and then expanding the design out to larger platforms later.

Reference: The term is most often associated with mobile designer Luke Wroblewski. (He even wrote a book on the topic.) The now widely accepted tactic not only helps the designer understand the constraints of her content on a smaller screen but it also helps "trim the fat" in order to focus on the most important elements. Think about it... do you really want 10 navigation items down your entire phone screen or can you live with 5 or 6 instead? It's great to think about these things as early in the process as possible. As a bonus, the more "fat-trimming" you do for the mobile experience, the more precise and lean your tablet and web experiences will be!

Thoughts/Questions: How will wearables affect mobile-first design thinking? Will there ever be a day when we design "wearable-first"?
