Halvorson, K. (2010) Content Strategy for the Web. “Chapter 1” Berkeley, CA: New Rider.
Usefulness is determined by the objectives and goals of the users (Halvorson 2006, 55). Taking web content as an example, if the content is not supporting fulfillment of those objectives and goals, the usefulness is lost. Thus usefulness is about the attributes of the website regarding the consumers’ need, whereas usability is about how efficiently and easily the content can be reached. A website can be well useful but it may not be reachable due to some organizational hindrance. Usability is also correlated with the structure and organization of the content (Halvorson 2006, 56). Yet when we talk about usability, usefulness is a precursor, or a necessary condition. Only when the website is both appropriate for the purpose and reachable to the users, would the value be improved. It is so easy for designer to add new contents to the web without a second thought. Think and plan before creating content for the web.
