UIUX

UIUX refers to the integrated practice of designing user interfaces (UI) and shaping user experiences (UX) across digital products. UI focuses on the visible elements the user interacts with—layout, typography, color, controls—while UX addresses the overall experience, including how users discover, learn, and complete tasks, and how information is organized. Together, UI and UX aim to make products usable, useful, and appealing, with UI as the visible layer and UX guiding the interaction strategy.

The term user experience was popularized in the 1990s by Don Norman, while user interface design has roots in early human–computer interaction. Modern UIUX practice has grown through iterative design, usability testing, and a growing emphasis on accessibility and cross-disciplinary collaboration among product managers, designers, and developers.

A typical UIUX workflow includes user research and personas, task analysis and information architecture, wireframes and prototypes, visual design, and usability testing. The process is iterative, with findings from testing guiding refinements to both UI and the interaction flow.

Guiding principles include consistency, learnability, feedback, discoverability, accessibility, and performance.

Common tools include Figma, Sketch, and Adobe XD, used to create wireframes, high-fidelity designs, and interactive prototypes. Success metrics track task completion rates, time on task, user satisfaction, and scales such as SUS.

UIUX applies to websites, mobile apps, software interfaces, and connected devices, requiring collaboration across product management, engineering, and user research to deliver coherent and inclusive experiences.
