Fidelity

The fidelity refers to the quality of the product, usually associated with prototype.

Fidelity can vary in: - Visual design - Content - Interactivity

Low fidelity (lo-fi) prototyping is a quick and easy way to translate high-level design concepts into tangible and testable parts. - To check and test functionality first

High fidelity (hi-fi) prototyping appear and function as similar as possible to the actual product that will ship. - To test with real users / get final approval
