Services — Product Design & UX

Design that ships — not design that stays in Figma.

From discovery research to design systems, we design products people want to use and keep using. 18 years of watching real users interact with software we've built has taught us what works — and what just looks impressive in a prototype.

User research synthesis — turning interview data into design decisions.

Our philosophy

Design is strategy — not decoration.

We've designed products for healthcare workers using gloved hands, logistics managers on moving vehicles, financial analysts across dual monitors, and consumers with two seconds of patience. Context is everything. Our design process starts with user research because assumptions about users are usually wrong. We test prototypes with real users before engineers write a line of code — because it's cheaper to learn early that the navigation model doesn't work than to discover it after three sprints of development.

Every design decision should be traceable back to a user need or a business objective. If it can't be, it's decoration.

The difference

The gap between good design and shipped design is engineering empathy.

Beautiful mockups that engineers can't build within the sprint are just art. We design with implementation in mind — every component maps to a buildable unit, every animation has a purpose and a performance budget, and every edge case is accounted for before handoff. Our designers sit in engineering standups because the best design decisions happen at the boundary between design intent and technical reality.

SDTC Digital project data

01

Research-driven decisions

Every design choice is backed by user evidence — interviews, analytics, or usability test results.

02

Accessibility from day one

WCAG 2.1 AA compliance built into the design process, not retrofitted after development.

03

Component thinking

Design systems that scale — reusable components, design tokens, and patterns that work across products.

04

Measurable improvement

Task completion rates, time-on-task, and error rates tracked before and after design changes.

From discovery to design system

Our design practice covers every stage of the product lifecycle — from understanding who your users are to maintaining the system that keeps the product consistent at scale.

Understanding users, their context, and their unmet needs before designing anything.

User interviewsRequired

Semi-structured interviews with representative users to understand goals, frustrations, and workarounds.

Competitive analysisDefault

Structured evaluation of how competitors solve the same problems — identifying gaps and opportunities.

Analytics reviewRecommended

Behavioural analytics synthesis to understand how users actually use the current product versus how they're expected to.

Contextual inquiryWhen needed

On-site observation of users in their actual environment — essential for enterprise and field-worker products.

Journey mappingDefault

End-to-end mapping of the user experience across touchpoints, identifying pain points and opportunities.

Common questions about product design

From teams evaluating their first design engagement to organisations scaling their design practice.

Enough to design with evidence, not assumptions — typically 8–12 user interviews for a new product, 4–6 for a redesign where we also have analytics. We're ruthlessly efficient with research because the goal is to inform design decisions, not to produce a research report. Every interview generates actionable insights that change something in the design.

How we work

Designers embedded in engineering — not throwing specs over the wall.

Our designers attend standups, review pull requests for visual accuracy, and iterate based on what production analytics reveal. The gap between design intent and engineering implementation is where user experience degrades — so we close that gap by making designers accountable for what ships, not just what's in Figma. This embedded model means fewer revision cycles, faster time-to-ship, and products that look and feel exactly like the design intended.

How we take a product from discovery to design system

01

Discover and research

User interviews, competitive analysis, analytics review, and stakeholder alignment. We build a shared understanding of who the users are, what they need, and what the business requires.

02

Define and structure

Information architecture, user flows, and the prioritised feature set that serves the user goals we discovered. Content strategy if the product is content-heavy.

03

Design and prototype

Wireframes to high-fidelity mockups, built as interactive prototypes and tested with representative users at each fidelity level.

04

Test and validate

Moderated usability testing with real users. Design decisions validated before they become code. Issues caught here cost a fraction of what they cost in development.

05

Ship and measure

Designers embedded in engineering sprints through to production. Post-launch analytics tracked against pre-design baselines to prove the design worked.
