85%

of usability problems are revealed by testing with just 5 users -- making usability testing the most efficient way to find interface failures

NNGroup, 2000

Usability Testing

Moderated and unmoderated usability testing with representative users that identifies interface problems, validates design decisions, and provides prioritized recommendations for improvement.

What's Included

Everything you get with our Usability Testing

Moderated Usability Test Sessions

5-8 test sessions with representative users performing real tasks while a researcher observes, noting confusion points, errors, and successful patterns

Task Completion Analysis

Quantitative metrics including task completion rates, time-on-task, error rates, and satisfaction scores that objectively measure interface effectiveness

Prioritized Recommendations Report

Detailed report with every usability issue documented, severity-rated, and accompanied by specific design recommendations prioritized for maximum impact

Our Usability Testing Process

Test Planning & Task Design

We define the test objectives, create realistic task scenarios that represent key user goals, establish success criteria, and recruit participants that match your actual user demographics.

Test Sessions

We conduct 5-8 moderated sessions where participants attempt tasks while thinking aloud. A researcher observes, notes confusion points, and asks follow-up questions. Sessions are recorded for team review.

Analysis & Severity Rating

We analyze session recordings to identify patterns across participants. Each usability issue is documented with frequency (how many users encountered it), severity (how much it impacted task completion), and specific moments of failure captured in video clips.

Recommendations & Presentation

We deliver a prioritized report with specific design recommendations for each issue, severity ratings, and supporting evidence. We present findings to your team with video clips that make usability problems viscerally clear to stakeholders.

Key Benefits

Discover Problems You Cannot See Internally

Your team is too close to the product to see its usability problems. Features that seem obvious to the people who built them confuse users who encounter them for the first time. Usability testing reveals these blind spots by showing you exactly how real users experience your interface -- often with surprising results.

Prioritize Fixes by Actual Impact

Usability testing produces a frequency and severity matrix that shows which problems affect the most users and cause the most friction. This evidence-based prioritization ensures your design and development resources address the issues that matter most, not the ones that are loudest in internal discussions.

Measurable Before-and-After Improvement

Usability testing produces quantitative metrics (task completion rate, time-on-task, error rate) that serve as baselines. After implementing fixes, retesting with the same tasks shows measurable improvement. This creates clear evidence that design changes actually improved the user experience.

Frequently Asked Questions

How many users do we need to test with?

Five users reveal approximately 85% of usability problems according to NNGroup research. We typically test with 5-8 users to ensure pattern reliability. For products with multiple distinct user segments, we recommend 3-5 users per segment. More users per segment produces diminishing returns.

What is the difference between moderated and unmoderated testing?

In moderated testing, a researcher observes and asks follow-up questions in real time, producing richer insights about why users struggle. Unmoderated testing uses recorded sessions without a researcher present, enabling larger sample sizes at lower cost. We recommend moderated testing for discovery and unmoderated for validation.

Can you test a product that is already live?

Absolutely. Testing live products is the most common scenario. Users interact with the actual product rather than a prototype, which produces the most realistic results. We also test competitor products to understand how your experience compares to alternatives your users evaluate.

How do you recruit test participants?

We recruit participants who match your actual user demographics using screening surveys. For B2B products, we recruit professionals in relevant roles. For consumer products, we match age, technical proficiency, and usage patterns. Proper recruitment is critical because testing with the wrong users produces misleading results.
