51.1 Requirements
Requirements is a UI/UX design skill that helps make products easier to understand, use, test, and improve. The method should be tied to a real user problem instead of decoration alone.
Step by step
- Define the user problem connected to Requirements.
- Collect evidence before jumping to a polished solution.
- Create the smallest flow, sketch, wireframe, prototype, or test needed to answer the question.
- Test the design with realistic content, states, and device constraints.
- Record what you learned and change the design based on evidence rather than preference.
10 practical examples
- Apply Requirements to a course website and explain the decision you made.
- Apply Requirements to a online store and explain the decision you made.
- Apply Requirements to a banking app and explain the decision you made.
- Apply Requirements to a school portal and explain the decision you made.

Hands-on example
UI/UX PRACTICE
Problem: A user struggles with Requirements.
Evidence to collect: interview, observation, analytics, or usability result.
Artifact: flow, sketch, wireframe, prototype, or test plan.
Success measure: task completion, clarity, error reduction, or satisfaction.
Next step: test one assumption.Expected output
A user-centered design artifact for Requirements plus a clear statement of what evidence would confirm or reject the design decision.
Practice exercise
Create a fresh example for Requirements using a different product, screen, component, or content set. Explain what changed and why.
