Research-led digital product design before development
Digital Otters designs websites and digital products by studying the decisions, tasks and constraints users bring to the interface. Research, information architecture, wireframes, prototypes, interface design and usability testing reduce avoidable rework before development.

UX and UI design: the short answer
UX and UI design services research how users actually behave, structure journeys around tasks rather than org charts, and deliver tested interface designs as a system developers can build accurately.
Design decisions are validated with users and analytics before build, because opinion is the most expensive way to settle an interface argument.

UX and UI solve related but different problems
UX design structures the journey, information and interactions. UI design creates the visual and interactive language through which people use that structure. Both must connect to business and technical constraints — and both fail in recognisable ways.
UX and UI design services from research to handoff
The project can focus on discovery, a redesign or complete product design. Each line below is a deliverable you can point at, not a phase name.
| # | Service | What it produces | Artefact |
|---|---|---|---|
| 01 | User and stakeholder research | Interviews, analytics, support insight, competitor patterns and existing-product review. | findings pack |
| 02 | Journey and task mapping | User goals, steps, decisions, pain points, dependencies and opportunities. | journey map |
| 03 | Information architecture | Navigation, taxonomy, labelling, content structure and functional requirements. | IA model |
| 04 | Wireframes and prototypes | Low- and high-fidelity layouts and clickable flows for the interactions that carry risk. | prototype |
| 05 | Interface design | Visual language, responsive behaviour, component states and content hierarchy. | UI mockups |
| 06 | Usability testing | Representative tasks, suitable participants, findings ranked by severity and business relevance. | test report |
| 07 | Design systems | Tokens, components, states, usage guidance, accessibility rules and contribution process. | Figma library |
| 08 | Developer handoff | Specifications, states, assets and acceptance criteria, followed by implementation review. | handoff spec |
Where the structure gets settled
Grey on purpose. Wireframes exist so hierarchy, labels and edge cases get argued about while changes are still cheap. Drop your own project wireframes into these frames.
Choose the right level of UX work for the risk
Fidelity is a budget decision, not a taste decision. Step through the ladder and watch the same mockup gain certainty — with what it produces and what it removes from your risk.
Structure, before anyone argues about colour
Low-fidelity layouts for the priority screens: hierarchy, blocks, labels and what has to sit above the decision point.
What you get- Annotated wireframes for priority screens
- Content and hierarchy requirements
- Open questions listed, not hidden
Grey blocks on purpose. Nobody reviews colour when there is none.
Journeys and information architecture
Navigation, taxonomy, labels, states and the flow between tasks — mapped before any screen is drawn.
What you get- Journey and task maps for priority flows
- Navigation and taxonomy model
- State and edge-case inventory
Every block now has a job, a label and an owner in the content plan.
Interactive prototype, tested with users
Clickable flows for the interactions carrying the most risk, tested with representative tasks and participants.
What you get- Clickable prototype of priority flows
- Usability findings ranked by severity
- Recommended changes before build
Numbered pins are observed friction points, not opinions from the room.
Interface system and developer handoff
Tokenised components, responsive behaviour, states, accessibility notes and acceptance criteria a developer can build from.
What you get- Tokenised component library in Figma
- Responsive, state and content specifications
- Handoff review of the implemented build
Colour, type and spacing are tokens now — defined once, inherited everywhere.
The interface, once the structure holds
High-fidelity mockups across desktop, tablet, mobile and the component sheet developers build from. Drop your approved project visuals into these frames.
// [CLIENT INPUT REQUIRED: replace these frames with verified project mockups, before-and-after architecture, measurable outcomes and approved testimonials.]
How a UX project moves from research to tested design
The sequence changes by service, but discovery, product decisions, design, implementation, validation and ownership stay explicit.
Clarify the problem, evidence, constraints, stakeholders and how design success will be evaluated.
Interviews, analytics, support data, competitive review and existing-product evidence.
Create flows, hierarchy, labels, states and functional requirements.
Build wireframes and prototypes for review and usability testing.
Apply visual language, responsive behaviour, components, accessibility and content hierarchy.
Provide specifications, states, assets and acceptance criteria; review the implemented experience.
Start with a UX audit of the current journey
Share the current platform, markets, user journeys, integrations, launch constraints and what the internal team needs to manage after delivery. We will recommend a focused scope.
- Which journeys carry the most interaction risk
- Where the current interface loses people, with evidence
- The level of UX work the risk actually justifies
- What a developer would need to build it accurately
The stack behind our UX and UI work
Major, verifiable platforms only. All code, accounts and infrastructure remain under your ownership.
Design, prototyping and design systems.
Behavioural evidence for design decisions.
Session recordings and heatmaps.
Accessibility and performance checks.
Designed as a system, not a stack of screens
Screens age; systems compound. We deliver UI as a tokenised component library in Figma — colour, type, spacing and states defined once, reused everywhere — so future pages inherit consistency instead of reinventing it, and development estimates stop being arguments.
Accessibility is designed in at this stage because retrofitting WCAG conformance costs multiples of building with it, and an interface more people can use is an interface more people can buy from.
Colour, type, spacing and radius defined once and inherited.
States, variants and behaviour, not just default appearance.
Designed in at component level, cheaper than retrofitting.
Contribution rules so the system survives the next hire.
UX benchmarks worth knowing
Reference figures from official documentation and published research — context for scoping, not promises.
| Metric | Typical figure | Source |
|---|---|---|
| First impressions | Formed in well under a second | Established UX research |
| Usability test size | 5 users surface most issues per round | Nielsen Norman Group |
| Accessibility standard | WCAG 2.2 AA | W3C |
| Form field effect | Fewer fields, higher completion | Conversion research |
When UX investment produces measurable return
A clear fit protects both sides. We would rather name a structural constraint before a scope is signed than design around it.
- 01The project has meaningful user journeys or interaction risk
- 02Stakeholders are willing to test assumptions before development
- 03Developers can collaborate on feasibility and implementation
- 04You need a reusable interface system rather than isolated screens
- 01You only want visual styling after all product decisions are fixed
- 02No access exists to users, analytics, support insight or stakeholder knowledge
- 03The project cannot allow any change after usability findings
- 04You expect a design file to replace product ownership and development QA

Questions buyers ask about UX/UI design
01What is the difference between UX and UI design?
UX design focuses on user goals, journeys, information and interactions. UI design focuses on the visual and interactive interface used to complete those journeys.
02What does a UX design agency deliver?
Deliverables can include research findings, personas or audience models, journeys, information architecture, wireframes, prototypes, usability findings, interface designs and a design system.
03Do you test designs with users?
Yes, when included in scope. We define representative tasks, recruit suitable participants and prioritise findings by severity and business relevance.
04Can you redesign an existing SaaS product?
Yes. We combine stakeholder and user research, analytics, support insight and product constraints before redesigning priority workflows.
05Do you create design systems?
Yes. Systems can include tokens, components, states, usage guidance, accessibility and contribution rules.
06Will developers receive specifications?
Yes. Handoff can include responsive behaviour, component states, content requirements, assets and acceptance criteria, followed by implementation review.
07Is accessibility included?
Accessibility is considered throughout the design process. The exact level of audit, testing and compliance support is defined in the project scope.
