User Testing & Usability Research Services
Ask Your Customer. Receive Valuable Feedback.
User Testing is the structured process of evaluating a product, service, or idea by observing real users as they interact with it. We uncover usability issues, validate design decisions, and reveal how customers actually behave. Whether you're testing early sketches, interactive prototypes, or live features, our qualitative and quantitative methods deliver actionable data to help you create more user-friendly, successful digital experiences. Every session is grounded in real-world use, and every insight is translated into clear, prioritised recommendations.
Client spotlight - Danone Nutricia
Project - Dietetic App Navigation & Functionality Testing for Danone Nutricia
Challenge - Danone Nutricia needed to validate the proposed navigation, functionality, and content of their new specialist dietetic app before committing to design and development. The team needed clear evidence of what would and wouldn't work for their highly specific user base.
Our Solution - We conducted structured usability testing with real target users, observing how they navigated prototypes and interacted with key features. Sessions were run in our testing lab and remotely, capturing both qualitative feedback and task success rates.
Outcome - The insights gathered directly shaped the app's information architecture, interaction design, and feature prioritisation. Critical usability barriers were identified and resolved before a single line of code was written, saving significant time, budget, and post-launch rework. The result was a smoother, more intuitive experience for patients and healthcare professionals alike.

User Testing - FAQs, Deliverables & Glossary
User Testing (Usability Testing) - A research method where real users attempt to complete tasks using a product or prototype while observers watch, listen, and take notes. The goal is to identify usability problems and gather qualitative and quantitative data.
Moderated Testing - A facilitator guides participants through tasks in real time, asking follow-up questions and probing for deeper understanding. Can be conducted in-person or remotely.
Unmoderated Testing - Participants complete tasks independently using a specialised platform. No facilitator is present; sessions are recorded for later analysis.
Prototype Testing - Evaluating a low or high-fidelity prototype before development begins. Used to validate concepts, navigation, and interaction design with minimal investment.
Accessibility Testing - Evaluating whether a product can be used by people with disabilities, including those who rely on screen readers, keyboard navigation, voice control, or other assistive technologies.
WCAG (Web Content Accessibility Guidelines) - Internationally recognised standards for making web content more accessible to people with disabilities. We evaluate against WCAG 2.1 AA level.
A/B Testing - Comparing two versions of a design or content element to determine which performs better on a predefined metric (e.g., clicks, conversions, task completion).
Task Completion Rate - The percentage of participants who successfully complete a given task. A core usability metric.
Severity Rating - A scale used to prioritise usability issues based on impact and frequency. Critical issues block task completion; minor issues cause frustration but don't prevent success.
Think Aloud Protocol - A technique where participants verbalise their thoughts, actions, and confusion as they navigate through tasks. Provides rich insight into user mental models.
Screener - A questionnaire is used to filter and select participants who match specific user profiles, demographics, or behavioural criteria.
Satisfaction Score - A subjective measure of participants' experience, often captured via post-test questionnaires such as the SUS (System Usability Scale) or SEQ (Single Ease Question).

What is user testing?
User testing is a structured process where real users interact with prototypes, designs, or live features to evaluate whether the experience is clear, intuitive, and aligned with their needs. It helps validate assumptions and identify usability issues before they impact customers.
Why is user testing important?
It ensures that real user behaviour – not assumptions, opinions, or internal bias – guides your product decisions. User testing reduces the risk of usability problems, improves accessibility, and dramatically increases the likelihood of a successful launch.
What can you test?
We test all digital services and products, including:
- Website and app usability
- E‑commerce flows and transactional processes
- Prototypes (from sketches to high-fidelity interactive models)
- Campaign landing pages and flows prior to development
- Accessibility with target users using assistive technologies
- Existing products to uncover issues and opportunities before redesign
When should we run user testing?
User testing is valuable at every stage:
- Business Case - Test existing services to uncover issues and opportunities before committing to redesign.
- Discovery Phase - Test early concepts, wireframes, or prototypes to guide direction and quickly determine sentiment. The earlier, the better. You will be amazed at what you learn.
- Design Phase - Validate navigation, layout, visual hierarchy, flows, and labelling. Again, the insights are incredible.
- Pre-Launch or Post-Launch - If the team has concerns, test quickly to identify usability barriers and opportunities for refinement.
- Continuous Optimisation: Regular testing of new features, journeys, or major updates.
How are participants recruited?
Participants are selected based on your user profiles or customer segments. They may be:
- Sourced from your existing customer lists
- Recruited through our trusted research partners
- Reached via targeted online outreach
- Drawn from our own compliant participant register
All recruitment processes comply with GDPR and ePrivacy requirements; participants provide informed consent, and personal data is minimised, securely stored, and anonymised in reporting.
How many participants do you typically test with?
Most usability rounds involve 5–8 participants, which is sufficient to uncover the most significant usability issues. Larger or more diverse audiences may require broader testing samples.
How are testing sessions run?
Sessions can be:
- Moderated - A facilitator guides participants through tasks in real time, asking follow-up questions and probing for deeper understanding (in‑person at our testing lab or remotely).
- Unmoderated - Participants complete tasks independently using a specialised platform; sessions are recorded for later analysis.
Every session follows a structured script with clear objectives and success criteria, ensuring reliable, consistent results.
How do you incorporate accessibility into testing?
Accessibility is built into our approach by:
- Including participants who use assistive technologies (screen readers, keyboard navigation, voice control)
- Evaluating against WCAG 2.1 AA success criteria
- Testing with device-level accessibility tools
- Conducting expert accessibility audits alongside user testing
Do you test prototypes or only completed features?
We do both, and strongly advise prototype testing. Validating concepts early helps steer design direction before development begins. This can save significant time, budget, and stress as your project evolves. Ignore this at your peril. Functional testing of completed features ensures the final experience performs as expected before launch.
What does the testing process involve?
- Setting the goals - Define key user tasks and success criteria.
- Recruitment - Source participants aligned with your user profiles.
- Testing - Observe and record interactions (in‑lab or remote).
- Analysis - Review behaviours, bottlenecks, and feedback.
- Recommendations - Deliver actionable, prioritised insights.
What deliverables do we receive?
You receive a structured insight report containing:
- Key findings and demonstrated usability issues
- Severity ratings and prioritised recommendations (sized for your team)
- Optional anonymised video clips or transcripts
- Strategic and tactical recommendations
- Suggested improvements to journeys, content, or interface design
How are findings incorporated into the project?
Insights are reviewed collaboratively with your design and development teams. They directly inform refinements to navigation, user journeys, layouts, and content. The goal is to make meaningful improvements before proceeding with further work.
Can user testing be done remotely?
Yes. Remote testing is widely used because it is efficient, cost-effective, and provides access to participants from different locations and backgrounds. It is quick to set up and activate.
How do you protect user data during testing?
All testing complies with GDPR and ePrivacy requirements. Personal data is minimised, securely stored, and anonymised for reporting. Participants provide informed consent before participating, and only necessary information is collected.
How often should user testing be carried out?
At minimum:
- Once during initial design to validate direction (always recommended before development commences).
- Once before launch to confirm usability and accessibility.
- Additional rounds should be conducted whenever major changes, new journeys, or new features are introduced.
