You want your customer-driven design product to be the right one, no matter how many iterations it takes. Low-fidelity prototyping is useful for its iterative, customer-focused approach.
Get better feedback
- When the prototype you present is too perfect, people don’t give the most useful feedback
It’s great for A/B testing
- You don’t want 2-3 pixel-perfect mockups, you want more rough mockups so you can select the most high-variance candidates.
Make the cost of mistakes cheap
- A low-fidelity prototyping process makes changing directions easier
Refine the page flow, not the pages
- With low-fidelity, it’s easy to draw lots of small pages and link them up in a flow, allowing for changes that feel natural when the prototype is rough
Work your way up to high-fidelity
- High-fidelity prototyping should be implemented in the later stages
