The final deliverables in a UI/UX design project typically include wireframes, high-fidelity mockups or prototypes, a design system or style guide, and design specifications or documentation. These deliverables provide a comprehensive overview of the design, including visual design elements, interactions, and functionality, and serve as a guide for developers during the implementation phase. In addition, a UI/UX design project may also include usability testing reports, research findings, and user personas, which help inform design decisions and ensure that the final product meets the needs of its target users.
