Capability 04 · Experience Engineering

Interfaces people understand the first time.

Experience Engineering joins research, interaction design and front-end engineering, so what is designed is what ships — and so the interface can grow without becoming inconsistent.

Business purpose

Lower support effort, training time and abandonment by making digital products clear, accessible and consistent.

Operational problems addressed

Signs this capability is needed.

  1. P1Customers abandon forms or call support for tasks the website should handle
  2. P2Every new screen looks slightly different from the last
  3. P3Accessibility issues are discovered after launch, if at all
  4. P4Designs are approved but change significantly during development
  5. P5Internal tools are so confusing that staff keep their own workarounds

What this includes

Inside Experience Engineering.

01Interaction and interface design
Flows, layouts and states designed from real tasks rather than feature lists.
02Design systems
Shared components, tokens and usage guidance in design files and in code.
03Accessibility engineering
Interfaces built to WCAG 2.2 AA guidance, checked with automated and manual testing.
04Front-end development
Performant, responsive interfaces implemented directly from the agreed system.
05Usability testing
Short rounds of testing with representative users before and after release.

Deliverables

  • Journey maps and key flows
  • High-fidelity designs and prototypes
  • Component library in design and code
  • Accessibility review notes
  • Usability findings and change log

Engagement and delivery

How this work is usually structured.

Engagement options

Delivery approach

  1. 01 · Understand

    We observe how people complete the most important tasks today, including where they hesitate or give up.

  2. 03 · Design

    Prototypes are tested before engineering starts; components are specified with every state, not just the ideal one.

  3. 04 · Engineer

    Designers stay involved through build to review the implemented interface against the agreed system.

What this can look like in practice.

Representative solution scenario · S4

Connecting customer and operational systems

Integration

Starting situation

Sales uses a CRM, delivery uses a project tool, finance uses an accounting system and customer service uses a help desk. Each holds a different version of the customer.

Operational friction

  • Won deals re-entered into delivery and finance systems
  • Customer service lacks order and contract context
  • Invoices delayed while information is gathered
  • Leadership reports reconcile figures from four exports

Proposed system

An integration layer with agreed data ownership, event-driven updates between systems, a customer view for service teams and a reporting model built on shared definitions.

Architecture outline

Expected categories of improvement

  • Information entered once
  • Faster hand-offs between teams
  • Better-informed customer service
  • One set of numbers for leadership

Frequently asked questions

Questions about Experience Engineering.

Yes. We often extend an existing visual identity into a working component system, collaborating with in-house designers rather than replacing them.

It is part of design and engineering from the start: colour contrast, keyboard use, focus behaviour, semantic structure and screen-reader checks are reviewed during each cycle.

Both. Keeping design and front-end engineering together is the main reason this capability exists.
