In the following list, we group together some of our articles and videos on topics related to qualitative usability testing. Within each section, the resources are shown in recommended reading order.
Qualitative Usability Testing: The Method
In a usability-testing session, a researcher (called a “facilitator” or a “moderator”) asks a participant to perform tasks, usually using one or more specific user interfaces. While the participant completes each task, the researcher observes the participant’s behavior and listens for feedback.
If you’re totally new to usability testing, we recommend you explore the following resources in order. If you have some prior experience, feel free to pick a subtopic and start there.

Remote Usability Testing
This list of resources covers remote usability testing. There are two primary types of remote usability testing:
- Remote moderated usability testing is conducted synchronously. The participant and facilitator meet virtually, often using video conferencing apps like Zoom.
- Remote unmoderated usability testing is conducted asynchronously — the researcher sets up the tasks and instructions in a testing platform, and the participant performs the tasks on their own while recording a video.
