Testing page designs
Typically, a Web site has a few unique pages (like the Home page) and a series of templates (like section front pages, article pages, and product pages) that are repeated throughout the site with different content. The next stage after wireframes is usually creating visual treatments (or “comps”) of these different types of pages. Where wireframes focus on interaction, comps focus on the visual design.
HOW YOU TEST IT:
Starting with the Home pages, you lead them by the hand through comps and ask them to do a narrative (page 75) of each one.
WHAT YOU GET OUT OF IT:
The purpose is to try to see if the visual design has introduced any usability issues. Can people figure out how each page is supposed to “work”?
