Until now, I've worked only on b2b sites, where navigation and user experience requirements were subservient to functional requirements. Now I'm working on my first consumer site at a large consumer product company. I'm in the post-test-plan pre-test-cases phase where I'm writing up the requirements / test case combinations matrix(s) and I'm amazed that the norm here is to itemize every user experience (design/graphics/text) & navigation requirement and write detailed test cases for them (instead of "verify the site matches the wireframes"). Is this the norm for consumer sites?
