  • Conducting user research
  • Developing user personas
  • Creating user flow diagrams and wireframes

How UI and UX Work Together

Great ui and ux aren’t competitors—they’re collaborators. A stellar user journey is only complete when smooth functionality meets stunning visuals.

Think of UX as the structure and UI as the style—you need both to build something truly outstanding.
