“After web site accessibility, ‘user experience’ is probably the phrase that most people tend to confuse usability with. Whilst this topic has been discussed by various experts in the respective fields, I feel the need to write about it for two main reasons. The first reason is that several posts I have encountered emphasize the distinction between these two terms, yet they fail to highlight the relationship that exists between usability and user experience. The second reason is that whilst most of the posts are similar in nature, I have found some minor, albeit very valid points scattered in various posts I have read. Therefore, the objective of this post is to discuss these two terms, whilst highlighting their differences and more importantly the relationship that exists between them in a clear, concise way.”
