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.

A winning variation isn’t just the version that “looks better”, it’s the version that truly and measurably outperforms the control. In this video, we break down what a winning variation is, how to determine it, and why statistical significance is essential for making confident, data-driven product decisions.

Software doesn’t go live overnight. It moves through a structured, repeatable process known as the software release life cycle — from initial planning to deployment and ongoing maintenance. In this video, we break down each stage of the release cycle: planning, development, testing, staging, deployment, and monitoring. You’ll also see how modern tools like Harness help teams automate CI/CD, feature flags, testing, and progressive delivery to ship better software faster and with less risk.

When running A/B tests, how do you know if the results are actually meaningful — or just random chance? That’s where the t-test comes in. In this video, we explain how t-tests help you evaluate whether changes in conversion rates, engagement, or performance metrics are statistically significant. You’ll learn how they work, when to use them, and why they’re essential for making confident product, marketing, and engineering decisions.

A/B testing is great — but what if you want to optimize more than one thing at a time? That’s where multivariate testing (MVT) comes in. In this video, we break down how MVT works, why it gives you deeper insights than A/B testing, and how you can use it to test multiple page or app elements at once. You’ll learn how to run multivariate tests, when to use them over A/B tests, and how Harness makes this seamless inside your CI/CD pipeline.
