Prototype Basse Fidélité

A Low-Fidelity Prototype is the simplest and fastest representation of a digital product idea. It often takes the form of quick sketches, static wireframes, or very basic mockups (black and white, simple shapes, minimal details).

This type of prototype never focuses on aesthetics, branding, or advanced interactivity. Instead, it concentrates exclusively on content, structure, and information hierarchy.

• Main objective: Quickly test structural concepts such as user flows and information architecture at the early stages of the design process.
• Key advantage: It is fast, inexpensive, and easy to modify. It is ideal for the ideation and early iteration phases of UX design, as it encourages teams to focus on logic and usability rather than visual details.
