UI UX design agency in New York City

Start with the evidence you have. Interviews and usability tests suit a new product or a high-stakes flow such as checkout or onboarding. For an existing product, analytics and support tickets can show where people get stuck without starting a full research programme. The choice affects how much evidence you gather and how much work goes into finding it.

Use low-detail wireframes to settle the structure early. A clickable prototype is more useful when you need people to try a flow, or when you want to show it to investors before writing code. For an early product, an established UI kit or open-source component library saves design effort; a custom visual language suits a brand where the interface itself is part of what customers pay for.

Consider the number of screens too. A small component library suits a marketing site or early product, while a full design system suits a larger product or several teams. If you have developers, design-only work is an option. If you want one party responsible for the finished product, choose design and build together.

For a business open to the public, US Department of Justice guidance says the ADA covers goods and services offered on the web. The guidance points to WCAG as a helpful standard. We design for accessible use with readable text, sufficient colour contrast, visible focus states, clear labels and tap targets large enough to use. Those choices need to be reflected in the screens and components your developers build.

Bring what you already have; these details give the discussion a practical starting point.

• Users and tasksList who uses the product and what each person needs to complete; mark tasks tied to revenue or support calls.
• EvidenceGather analytics, session recordings, support tickets or sales call notes showing where users get stuck.
• Brand filesShare your logo, fonts, colours, guidelines and any existing design files.
• Technical limitsAsk your developers which front-end framework and component library they use, and what the back end cannot yet do.
• Familiar productsNote competitors or common tools your users know, including what works and what annoys you.

  Polishing too early

  Agree the flow before investing in finished visuals, so attractive screens do not need restructuring.

• !

  Ignoring build constraints

  Check the chosen front-end framework and existing component library before designing components that are difficult to build.

• !

  Making forms hard to use

  Avoid low-contrast text, tiny tap targets and fields labelled only with placeholder text. Give each field a clear label.

  Walking away at handover

  Keep the designer available for development questions, so the build does not drift through guesswork.
