Detailed Usability Study
This detailed usability study template is designed for UX researchers conducting moderated or unmoderated user testing sessions. It includes task-based success ratings, time tracking, difficulty assessments, and the industry-standard System Usability Scale (SUS). The form guides participants through rating multiple tasks, provides space for observations, and calculates aggregate usability scores to help you identify friction points and prioritize improvements.

Frequently Asked Questions
What is a usability study?
A usability study is a research method where you observe users attempting to complete specific tasks with your product. It helps identify usability issues, measure task success rates, and understand user frustrations to improve the product experience.
How many tasks should I include?
We recommend 3-5 key tasks per session to avoid participant fatigue. Each task should represent a critical user journey or common user goal. You can customize the task list based on your research objectives.
What is the SUS (System Usability Scale)?
SUS is a validated 10-question assessment that provides a reliable measure of perceived usability. Scores range from 0-100, with 68 being average. The template automatically calculates the SUS score based on participant responses.
Can I use this for remote usability testing?
Yes! This form works for both moderated in-person sessions and unmoderated remote testing. For remote sessions, consider adding screen recording instructions or integrating with your testing platform.
How do I interpret task completion rates?
Track the percentage of users who complete each task successfully. Industry benchmarks suggest 78% success rate is average. Tasks below 70% indicate significant usability issues that need attention.
