10 Questions to Ask Your UX/UI Design Provider
Frequently Asked Questions
What is the difference between UX and UI design?
UX (user experience) focuses on how a product works and feels — information architecture, flows, and usability. UI (user interface) focuses on how it looks — visual design, typography, and interaction patterns. Both are critical; great products need both.
How long does a UX/UI design project take?
A typical web or app redesign takes 8–16 weeks: 2–3 weeks research, 2–3 weeks wireframes, 3–4 weeks visual design, 2–3 weeks iteration and handoff. Complex projects with extensive research take longer.
Do I need UX research before starting design?
Yes. Skipping user research leads to designing for assumptions rather than actual user needs — the most common cause of expensive post-launch redesigns. Even 5 user interviews reveal the majority of critical usability issues.
What deliverables should I expect from a UX/UI agency?
Research summary, user personas, journey maps, wireframes, interactive prototype, visual design specs, a design system with reusable components, and developer handoff documentation with behavior specifications.
