User Experience Themes, Part I: Craft and Engineering (Peter Merholz) -- "In the field of user experience the products we develop must, above all else, *work*. What I mean is that they must function in order to support their users. Before it looks good, before it conveys the latest business direction, before it satisfies the designer's artisanal desires, the product must enable users to support their tasks at hand. Such a functional approach, by necessity, requires an engineering approach."
