This document discusses the differences between user experience (UX) and user interface (UI) design. UX focuses on how a site works and feels from the user's perspective, aiming to fulfill business goals like user acquisition, activation, and retention. Some key UX components include user definitions, site maps, user flows, and wireframes. UI, on the other hand, focuses on visual design elements like branding, colors, fonts, and wireframes to provide users with solutions to problems. The document outlines common UX and UI design tools and compares freelance versus agency versus in-house design approaches.
