Usability Testing
Usability testing measures whether real users can complete real tasks in your software — and where they fail. The output is task-completion rate, time-to-task, error rate, and qualitative observation notes. Done well, it produces a prioritised list of design changes ranked by user impact. Done badly, it produces a deck no one acts on.
Our approach combines moderated remote sessions (Zoom / Microsoft Teams with screen-share + think-aloud protocol) for in-depth task observation, and unmoderated tools like Maze or UserTesting for breadth at scale. For Australian customers we recruit AU participants where the user base demands it (consumer products, public-facing services); for B2B and admin tools we recruit by role rather than geography. Sample sizes follow Nielsen's rule — five users per persona surfaces ~85% of usability issues — supplemented with quantitative testing on the remaining ambiguous flows.
What is Usability Testing?
Usability testing is a method of evaluating a product by testing it with representative users. During a usability test, participants try to complete typical tasks while observers watch, listen, and take notes. The goal is to identify any usability problems, collect qualitative and quantitative data, and determine the participant's satisfaction with the product.
Benefits of Usability Testing
- Improved User Experience: Identifies pain points and areas where users struggle
- Increased User Satisfaction: Ensures the application meets user expectations and needs
- Reduced Support Costs: Fewer user questions and support tickets when the interface is intuitive
- Higher Conversion Rates: Better usability leads to improved user engagement and conversions
Usability Testing Methods
Moderated Testing
A facilitator guides participants through tasks, asking questions and observing behaviour in real-time. This method provides rich qualitative insights.
Unmoderated Testing
Participants complete tasks independently, often remotely, while their interactions are recorded. This method allows for testing with a larger, more diverse user base.
How We Run Usability Testing
Each session has a written task script and a measurable success definition agreed upfront with the product owner. We record sessions with consent (Lookback or built-in Zoom recording), code observations against a fixed taxonomy (navigation, terminology, control affordance, feedback, error recovery), and rank findings by severity using the standard 1–4 Nielsen severity scale. The deliverable is a written report with prioritised recommendations and reproducible evidence — not a video reel.
Where the testing serves an accessibility goal as well, we layer axe DevTools, Pa11y, and Accessibility Insights into the session protocol so WCAG 2.1 AA conformance issues surface alongside the usability findings. The two reports cross-reference each other so engineering teams have one consolidated remediation backlog.
Want a usability assessment with a prioritised, evidence-backed remediation plan?
Two ways in: book a 30-minute discovery call (better for CXOs scoping a project) or request a written test-strategy review of your current setup (better for CTOs and engineering leads who want a second opinion). Both are no-obligation.
How We Test Industry-Specific Workflows
Tailored QA for offline, compliance, and data-heavy products across Australia/APAC and regulated regions.
