Usability itself was a something I'd encountered, but never given much thought to. Now that I'm making my own website, it's something I need to be aware of because it does have an impact on visitors to a site.
The priniciples of usability as put forth by Nielsen make sense. They're easy to comprehend and it can be understood why these principles of usability--and moreover usability itself--are so crucial to web design.
I also liked how Nielsen was candid with the reader about why it is important to put the time and effort into usability testing for their company's website. He mentioned something that has been very true (at least in my experience with poorly designed websites): If they don't get what they need easily, users will leave your site.
Nielsen writes,"There's no such thing as a user reading a website manual or otherwise spending much time trying to figure out an interface. There are plenty of other websites available; leaving is the first line of defense when users encounter a difficulty". That's one of the benefits, and in this case drawbacks, of the Internet. There's such a wealth of knowledge out there that the answer to one question can be found in probably hundreds of other places.
I read an article about the multiple attempts to re-vamp the Georgia Tech Library's website. I found the article, "Redesigning for Usability: Information Architecture and Usability Testing for Georgia Tech Library's Website" on EBSCOhost through the Shepherd University library, but read the full-text PDF file from another site.
In this article, authors Heather Jeffcoat King and Catherine M. Jannik discuss the changes made to the Georgia Tech Library website beginning with the website's design in 2002. In between pages of the article, there are screen shots of the library website's homepage at different major intervals. The authors discuss the changes made and the processes of usability testing along each stage, and the screen shots helped me understand the progress better than just trying to picture the changes in my head. Figure 1 on page 3 shows a boring and confusing list of services for users to guess which one to go to, whereas Figure 3 on page 4 shows a more visually appealing homepage with the links from the list in Figure 1 neatly organized into a sidebar.
The article concluded with a statement that this project is ongoing, and that although the library's website has improved (an understatement!) Georgia Tech does not consider this the end. There are plans for more testing and incorporating the university's Digital Initiatives department into the current library site (King 7).
