Usability Testing Explained: How to Evaluate User Experience and Improve Product Design with Harness

Harness

Nov 30, 2025

Usability testing is a powerful method for understanding how real users interact with your product, and uncovering the friction, confusion, and hidden roadblocks that can impact the user experience.

In this video, we break down what usability testing is, why it matters, and how observing real user behaviour can help teams create more intuitive, user-friendly software.

You’ll learn how usability testing differs from other methods like A/B testing or general user research, why defining a clear objective is essential, and how to choose the right participants. We also walk through key steps in the testing process, from observing user actions and emotional responses to analysing patterns and prioritizing improvements.

Finally, we show how organizations can use Harness feature flags to streamline usability testing, rolling out features safely to test groups, gathering real-world insights, and iterating quickly without disrupting the broader user base.
