Do you make these 4 mistakes when carrying out a usability review?: "For example, take a principle like ‘User control and freedom’. This is one of Nielsen’s principles, developed prior to the web, and is expressed as follows: “Users often choose system functions by mistake and will need a clearly marked ‘emergency exit’ to leave the unwanted state without having to go through an extended dialogue.” This principle was developed for the graphical user interfaces that were in existence at the time. As a reviewer, this would remind you to check (amongst other things) that dialog boxes had a cancel button and that the interface supported undo. Fast forward to the web and these checks aren’t relevant to most web pages. To re-interpret this principle for web pages, we’ll probably want to check (amongst other things) that the web site doesn’t disable the back button and that there’s a clearly marked route back to ‘Home’ from all pages in the site.
