It’s getting better and better but, still, how many times have you had to justify why user experience matters and what it actually means? To be prepared, as part of your UX toolbox, you should have a set of examples and visuals to ground your arguments. Case studies are great ways to exemplify the relevance of UX for product and service development. Graphics are also great tools to become the perfect advocate of UX.
There are lots of classifications and forms to provide a visual overview of the User Experience field. The truth is that UX is a pretty high level term and often too ambiguous for people outside the field. What does UX exactly mean? Is it a philosophy, a process, a guideline, a standard, a discipline? It will definitely puzzle your colleague/boss/client/grandmother when you reply that UX is all of the above!
