User experience design is frequently confused with making screens pretty, but its real work happens earlier and deeper: understanding people, structuring solutions, and verifying that things actually work for users. This lesson maps the discipline so you know what you are learning.
The Scope of UX Work
UX covers the entire journey someone has with a product: discovering it, learning it, using it daily, and recovering when things go wrong. Practitioners research user needs, define flows and structure, prototype solutions, and test them. Visual interface design is one layer within that larger scope.
UX Versus UI
UI design is the craft of the visible surface: layout, type, color, components, and states. UX is the logic beneath it: whether the right features exist, whether steps make sense, whether people succeed. A gorgeous interface on a confusing flow is still a failed experience.
Evidence Over Opinion
The defining habit of UX work is deciding with evidence: observing users, measuring task success, and testing assumptions before building. Designers still exercise judgment constantly, but they treat their own preferences as hypotheses. This mindset is what the rest of the course trains.
Action Step
Pick an app you use daily and write down its full journey from first discovery to routine use. Mark two moments where the experience helped you succeed and one where you struggled, and guess what research might have caught the struggle.
