Morville’s facets of user experience—definitions (adapted from46 65)
| Facet | Explanation |
| Usability | Refers to how simple and easy to use the product is. The product should be designed in a way that is familiar and easy to understand. The learning curve a user must go through should be as short and painless as possible. |
| Usefulness | Refers to how much the product fills or answers an information need. If the product is not useful or fulfilling the user’s wants or needs, then there is no real purpose for the product itself. |
| Desirability | Refers to the visual aesthetics of the product, which needs to be attractive and easy to translate. Design should be minimal and to the point. |
| Findability | Refers to how easy to navigate the product is. If the user has a problem they should be able to quickly find a solution within the product, and the navigational structure should also be set-up in a way that makes sense. |
| Accessibility | Refers to how accessible and adapted the tool is, even to users with special needs, so that they can have the same user experience as others. |
| Credibility | Refers to how trustworthy the product is. Note that this may refer to the product itself, as well as to content that informs it (which is not necessarily an attribute of the design). |
