The UMUX-Lite is a two-item standardized questionnaire that, since its publication in 2013, has been adopted more and more by researchers who need a concise UX metric. Figure 1 shows the standard version with its Perceived Ease-of-Use (“{Product} is easy to use”) and Perceived Usefulness (“{Product}’s capabilities meet my requirements”) items. Figure 1: Standard
The Net Promoter Score (NPS) is a widely used metric, but it can be tricky to work with statistically. One of the first statistical steps we recommend that researchers take is to add confidence intervals around their metrics. Confidence intervals provide a good visualization of how precise estimates from samples are. They are particularly helpful
Happy New Year from all of us at MeasuringU! 2020 was a crazy year, but we still managed to post 48 new articles and continued improving MUIQ, our UX testing platform. We hosted our seventh UX Measurement Bootcamp, this time virtually. The change of format was a challenge, but it was fantastic to work with
In an earlier article, we reviewed five competing models of delight. The models differed in their details, but most shared the general idea that delight is composed of an unexpected positive experience. Or, for the most part, delight is a pleasant surprise. However, there is disagreement on whether you actually need surprise to be delighted.
We love writing about measures at MeasuringU. We write about measures we’ve created (SUPR-Q®), industry standards (SUS, NPS, and TAM), emerging industry standards (UMUX-Lite), and lesser-known ones (lostness). Jim Lewis and I also have a chapter dedicated to questionnaires in Quantifying the User Experience. We’ll often encounter a new measure when working with clients, as
What gets measured gets managed. It’s more than a truism for business executives. It’s also essential for the user experience professional. In business, and UX research in particular, you don’t want to bring focus to the wrong or flawed measure. It can lead to wrong decisions and a misalignment of effort. In an earlier article,
No one likes getting lost. In real life or digitally. One can get lost searching for a product to purchase, finding medical information, or clicking through a mobile app to post a social media status. Each link, button, and menu leads to decisions. And each decision can result in a mistake, leading to wasted time,
We talk a lot about measurement at MeasuringU (hence our name). But what’s the point in collecting UX metrics? What do you do with study metrics such as the SUS, NPS, or SUPR-Q? Or task-level metrics such as completion rates and time? To understand the purpose of UX measurement we need to understand fundamentally the
Businesses are full of metrics. Increasingly those metrics quantify the user experience (which is a good thing). Collecting consistent and standardized metrics allows organizations to better understand the current user experience of websites, software, and apps. It allows teams to track changes over time and compare to competitors and industry benchmarks. The idea of quantifying
The PURE (Practical Usability Rating by Experts) method is an analytic technique that identifies potential problems users may encounter with an interface. In a PURE evaluation, evaluators familiar with UX principles and heuristics break down tasks into small steps. They then rate each step, from 1 to 3, based on a pre-defined rubric. The higher the
