The idea is that, no matter what you're doing, there's a user-centered way of doing it. Users should be considered throughout the website design process. Usability should not be an afterthought.

Analysis Determine the goals for the website from the perspective of the user and the business.
Determine the user needs and target usability requirements. Evaluate existing versions of the site. Perform a competitive analysis. Perform user interviews and surveys. Conceptual Design Sketch out a site design and architecture at an abstract level.
