Analyse Usability Test Results
Identify patterns, severity ratings, and priorities from 5 test session summaries.
Remote Unmoderated Testing Strategy
Design a remote unmoderated testing programme with task design and metrics.
Usability Testing & User Task Protocols
Usability testing validates whether real users can accomplish tasks efficiently in an interface. UX leads assess designers on creating unmoderated/moderated usability test plans, measuring task completion rates, logging user errors, and calculating System Usability Scale (SUS) scores.
1. Usability Test Protocol & Task Scenarios Document
Testing plan outlining realistic user task scenarios, success criteria, and post-task questionnaire scripts.
2. Video Session Observation & Error Log
Session log documenting user task completion rates, time-on-task metrics, misclicks, and verbalized frustrations.
3. System Usability Scale (SUS) Benchmark Report
Quantitative report computing SUS survey scores (0-100) and outlining UX remediation priorities.
Frequently Asked Questions (Usability Testing)
How is the System Usability Scale (SUS) score calculated?
SUS uses a 10-item Likert scale survey. Individual item scores (0-4) are summed and multiplied by 2.5 to yield a normalized usability benchmark score from 0 to 100.
What is an acceptable System Usability Scale (SUS) benchmark score?
An SUS score above 68 is considered average; scores above 80 indicate excellent usability.
What is the difference between moderated and unmoderated usability testing?
Moderated testing has a live facilitator guiding the participant in real time. Unmoderated testing allows users to complete tasks independently via automated platforms (like Maze or UserTesting).
