User Experience design has always been, and continues to be, a field riddled with ambiguous labeling and nomenclature. We hear all sorts of conjecture and debate as to what terms have what specific meaning. Are profiles and personas the same thing? When exactly do wireframes become mock-ups? Is “mock-up” supposed to hyphenated? These are issues of semantics, and when it comes to the actual meat of the work we do, we could call a wireframe a “whosamawhatsit” and it wouldn’t change it’s purpose. From the perspective of standardizing our professional space, common labeling is important. This is not in doubt. Client, asset, and project management aside, there is something vital to the decisions that we make as designers that is not addressed as often as it should be: Science.
