26.1 Foundations

Foundations 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

  1. Define the user problem connected to Foundations.
  2. Collect evidence before jumping to a polished solution.
  3. Create the smallest flow, sketch, wireframe, prototype, or test needed to answer the question.
  4. Test the design with realistic content, states, and device constraints.
  5. Record what you learned and change the design based on evidence rather than preference.

10 practical examples

  1. Apply Foundations to a course website and explain the decision you made.
  2. Apply Foundations to a online store and explain the decision you made.
  3. Apply Foundations to a banking app and explain the decision you made.
  4. Apply Foundations to a school portal and explain the decision you made.
  5. Apply Foundations to a clinic booking system and explain the decision you made.
  6. Apply Foundations to a dashboard and explain the decision you made.
  7. Apply Foundations to a restaurant site and explain the decision you made.
  8. Apply Foundations to a mobile app and explain the decision you made.
  9. Apply Foundations to a creator site and explain the decision you made.
  10. Apply Foundations to a business landing page and explain the decision you made.

Hands-on example

UI/UX PRACTICE
Problem: A user struggles with Foundations.
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 Foundations plus a clear statement of what evidence would confirm or reject the design decision.

Common mistake: Treating Foundations as a visual preference instead of connecting it to a user need, constraint, or testable outcome.

Practice exercise

Create a fresh example for Foundations using a different product, screen, component, or content set. Explain what changed and why.
