What is the difference between UX and UI design?

UX decides what the product does and in what order. UI decides what it looks like. Both are design, they need different skills, and confusing them produces a beautiful interface nobody can complete a task in.

UX work produces research findings, information architecture, flows and wireframes. UI work produces the visual system — type, color, spacing, components and states — that turns that structure into something usable and on-brand.

They are usually sold together and for most projects that is right. But they are separable purchases: plenty of companies buy research and structure, then apply their own design system.

How much user research does a project actually need?

Enough to be confident about the problem, and rarely more. Research with no decision attached produces a thorough document that changes nothing — which is the most common way this work gets wasted.

For most commercial projects that means a handful of interviews, a review of what analytics already show, and usability testing on the prototype before build. Weeks, not months, and it reliably changes the plan.

Larger programs make sense when the audience is genuinely unfamiliar, the domain is specialized, or being wrong is expensive. Outside those cases, more research mostly buys confidence you already had.

Why do designs look different once built?

Because states and edge cases were not designed, so the developer made reasonable guesses. A design file typically shows the ideal case: perfect content length, nothing loading, nothing empty, no errors.

Real interfaces spend a lot of time in the other states. A button being pressed, a field in error, a list with nothing in it, a name three times longer than the placeholder. If those were not designed, they were decided in code.

The other cause is values rather than states. Spacing that varies arbitrarily gives a developer nothing to implement, so they build to a grid and the result is close without matching. Named tokens fix that by making the values explicit.

Do we need a design system?

If more than one person will make design decisions, or the product will keep growing, yes. For a small site designed once by one person, it is overhead you may not recover.

The signal that you needed one and did not build it is recognizable: several button styles, three shades of the same gray, and nobody able to say which version is correct. That is not carelessness — it is a hundred reasonable decisions made without a shared reference.

What a system changes is which choice is the easy one. Named tokens, components with their states already decided, and documentation that answers "which do I use" without a meeting. Consistency then happens without anyone policing it.

How does accessibility fit into design work?

It shapes the first decisions rather than being reviewed at the end, because the expensive accessibility problems are structural and the cheap ones are cosmetic.

The structural half is heading order, focus order, whether interactive things look interactive, and whether a journey can be completed by keyboard and with a screen reader. Those are decided when the flow is designed; retrofitting them means redoing the flow.

The cosmetic half is contrast, target size and visible focus states. A brand palette whose accent fails against white is common, and the moment to discover it is while the palette is being chosen rather than after it has been applied to two hundred components.

We test against WCAG 2.2 AA, which is a published standard with measurable criteria rather than a matter of judgement. It is also increasingly a legal obligation in the US market, and designing for it produces a better interface for everyone — sufficient contrast, adequate touch targets and honest error messages are simply what careful design looks like.

Are personas worth building?

Only when they are built from research and describe behavior rather than demographics. A persona assembled in a workshop from assumptions is a picture of what a team already believes, and it will confirm every decision it is consulted on.

What makes one useful is grounding: what this person is actually trying to do, what they currently do instead, what stops them, and what vocabulary they use. Age, job title and a stock photograph contribute nothing to a design decision.

For most projects a smaller artefact works better — a short list of the jobs people are hiring the product to do, each with the context around it. That is faster to produce, harder to argue with, and it maps directly onto flows.

Where personas do earn their place is in large organizations with several teams making decisions separately. There the value is shared language rather than insight, and that is a legitimate reason to build them.

What is interaction design and where does it matter most?

Interaction design decides what happens between the click and the result: what responds, how quickly, what the person sees while they wait, and what happens when it fails.

It matters most where an action has consequences. A destructive action needs confirmation and, where possible, reversal. A long operation needs progress that distinguishes slow from broken. A form submission needs to preserve what somebody typed when validation rejects it — losing entered work is the single most reliable way to end a session.

The states are where interaction design is usually skipped. Default, hover, focus, active, disabled, loading, empty and error exist for every interactive component, and a design specifying only the first one leaves seven to be invented at build time under deadline.

Motion belongs here too, and its job is to explain rather than decorate. A transition that shows where a panel came from helps; one that delays a response the person already asked for does not. Anything animated also needs a reduced-motion path, because a real portion of users have asked their system for one.

How do you choose a UI/UX design agency?

Ask what they would do in the first two weeks. A UX design agency that starts with research has a different answer from a UI design agency that starts with screens, and neither is wrong — but you should know which you are buying.

Ask how they test. "We validate with stakeholders" means the design was reviewed, not tested. Usability sessions with people who match your users are a different activity with a different cost, and the distinction matters more than any portfolio.

A product design agency working on an existing product should also want your support tickets and analytics before quoting. If nobody asks for evidence of how the current product fails, the redesign is being run on taste.
