“UX dept” is used to represent the gap between a product’s ideal user experience and its actually quality. The expression gives life to that gap and provides designers a language for perceiving and evaluating the real state and quality of UX experience in terms of the 4 emotional measures: functional, reliable, usable, and pleasurable. According to Aarron Walter’s “Hierarchy of User Needs,” which follows Maslow’s framework of Hierarchy of (Human) Needs, the functional measure lives at the lowest level of the quality axis and supports the increasingly qualitative measures: reliable, usable, and pleasurable; the latter sitting at the top of the pyramid denoting the ideal, target or “peak” experience.

This notion is interesting to me because it gives me a quality matrix to place my work against and aim for when designing a user experience. It seems the work delivered in UX focusses more on the first 3 floors of the pyramid, often sacrificing the best quality defining measure; the pleasurable. For the author of the article, Andrew Walter, “UX dept” only takes place when designers think an experience can or should be better. It is the result of “cutting corners” and making fast constraint-based decisions to the detriment of a pleasurable and best user experience.
