Prototype

Prototypes are interactive mockups of a user interface that simulate functionality and user interactions, bridging the gap between static wireframes and final development.

Why need prototype?

1. Visualizing Ideas

It turns abstract concepts into tangible, interactive models. Prototypes help designers, developers, and stakeholders align on what a product should look and feel like.

2. Early Usability Testing

Before investing time and resources in development, prototypes let you test user journeys, discover friction points, and gather real-world feedback from actual users.

3. Fail Fast, Learn Faster

It’s much easier and cheaper to fix problems at the prototype stage than after a product is built. Prototyping enables rapid iterations and quick decision-making.

4. Stakeholder Buy-In

An interactive prototype communicates ideas far better than static visuals. It makes presentations more persuasive and helps non-designers (like clients, managers, or investors) understand the product vision.

5. Smooth Handoff to Developers

Prototypes clarify functionality, animations, and interactions, reducing miscommunication and speeding up the handoff between design and development teams.

Common Mistakes to Avoid

• Over-designing too early: wasting time polishing before testing basic usability
• Ignoring user feedback: building based on assumptions instead of evidence
• Skipping error states: forgetting to prototype what happens when things go wrong
• Poor device targeting: only testing desktop when most users are on mobile
• Too complex too soon: making it difficult for stakeholders to give clear feedback
