Prototyping

What is the main purpose of prototyping?

To reduce business risk by testing ideas before full development.

Define “prototype” in UX design.

A simplified, testable version of a product that simulates functionality and flow.

What is a “wireframe”?

A static layout showing structure and content placement without interactivity.

What’s the key difference between a wireframe and a prototype?

Wireframes show layout; prototypes simulate interaction.

Name two types of fidelity in prototypes.

Low-fidelity (sketches, wireframes) and high-fidelity (realistic, interactive).

Give one example of low-fidelity prototyping.

Paper sketches or clickable mockups.

Give one example of high-fidelity prototyping.

Interactive simulation with realistic data or animations.

What tool is most used for collaborative prototyping?

Figma.

What feature in Figma allows simulating pop-ups and tooltips?

Overlays and modals.

How does prototyping improve collaboration?

It lets teams co-design and align expectations before coding.

What should be tested first in prototypes?

The riskiest assumptions about user behavior or understanding.

What’s the benefit of validating language in prototypes?

Ensures terms and labels match users’ mental models.

Why simulate loading or empty states in prototypes?

To test how users perceive performance and avoid confusion.

What’s the main takeaway from the lecture?

Don’t skip prototyping — it closes the gap between expectations and real user needs.
