"Create a Design Plan" - I am adding information on workflow design.
"Support Development" - Some pages posted. Others yet to come.
"Support Site Sustainment" - Still in progress.
Depending on the purpose of your page, a feature can be just as important, if not more improtant than content.
When collecting requirements, you might have performed a feature analysis. Almost anything that can be done on a site can be described as a feature. In this step of the design process, I propose you need to focus on features that are interactive components one finds on a page.
