Usability is the ease of use and learnability of a human-made object. The object of use can be a software application , website, book, tool , machine , process, or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers , technical writers , marketing personnel, and others.
