20.1 Base Unit

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

Hands-on example

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

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

Practice exercise

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