The UX-Lite® is a relatively new metric, but it is versatile, short, and increasingly popular for UX research. It measures perceived usability and usefulness with just two items. But if you’re using the UX-Lite to compare products or to see whether you’ve improved over time, what sample size do you need? Yes, the sample size
The UX-Lite® is a relatively new but increasingly popular metric for UX research. Its two items generate an overall score and subscale scores on ease and usefulness from 0 to 100. The UX-Lite predicts future product usage as well as or better than the original and longer Technology Acceptance Model (TAM). The ease score also
The UX-Lite® is an increasingly popular UX metric. There’s a reason for its popularity. It’s a simple two-item questionnaire that measures perceptions of the user experience of any interface (product, app, website).

Happy New Year from all of us at MeasuringU®! In 2025, we posted 48 articles and continued to add features to our MUiQ® UX testing platform to make it even easier to develop studies and analyze results. We hosted our 12th UX Measurement Bootcamp—a blended virtual event attended by UX practitioners who completed a combination
At MeasuringU®, we don’t just use UX metrics—we create them. But what have we created, and what have we just used or extended? Across our combined careers, we (Jeff and Jim) have published 16 psychometrically qualified UX metrics (both creating original and modifying existing questionnaires) plus a method for combining prototypical usability metrics, and we
AI is rapidly changing. By the time we write about the latest features and performance benchmarks, they are replaced by newer features and benchmarks. But are all those features and benchmarks noticed by users? Perhaps. The speed of change in AI shouldn’t stop us from taking a snapshot of the user experience. Even with rapidly
The word “standardized” conjures memories of high-stakes tests. In the context of UX research, when we talk of standardization, we’re often referring to standardized questionnaires. Standardized questionnaires have gone through the process of psychometric validation. That means the items being used have gone through dozens or hundreds of possible variations, and the final versions are
We know that for a lot of UX professionals, quantitative UX research sounds like an oxymoron. You might have been involved in a few debates that included topics like: Whether you should even use numbers in UX research Which is the best UX metric to use Whether you’re using the right statistical test on your
In the movie 2001: A Space Odyssey (made in 1968), a vision of the future included video conferencing. And 1989’s Back to the Future’s vision of 2015 included not only video conferencing but also getting fired over it. While we may scoff at how hoverboards and flying cars still haven’t arrived, it’s now normal for
Early and often is not just advice for voting in Chicago—it’s also one of the key principles for designing for a usable experience. Testing an experience while it’s still in its prototype stage allows you to find and fix problems before they become difficult and expensive to fix. User experiences with prototypes (even low fidelity
