Five-star reviews. Whether you're rating a product on Amazon, a dining experience on Yelp, or a mobile app in the App or Play Store, you can see that the five-star rating system is quite ubiquitous. Does the familiarity of stars offer a better rating system than traditional numbered scales? We recently reported a comparison between standard five-point linear numeric scales with 0–100-point slider scales made with UMUX-Lite

Software dominates our professional and personal lives. A product's usability, in addition to its features and capabilities, is an important influence on how likely users are to adopt new technology and recommend the software. Between 30 and 60% of the variation in Net Promoter Scores is determined by a product's usability. Customers tend to recommend products they have positive experiences with. Similarly, bad experiences lead customers

Despite the attention consumer-based mobile apps, websites, and software get, a lot of the world depends on business software. Business software supports core functions for organizations such as productivity tracking, communication, accounting, and sales. Several products also have a fair amount of crossover between business and consumer usage. Along with their features and capabilities, the user experience of software is a key determinant of how

10 Things to Know about the Technology Acceptance Model

A usable product is a better product. But even the most usable product isn’t adequate if it doesn’t do what it needs to. Products, software, websites, and apps need to be both usable and useful for people to “accept” them, both in their personal and professional lives. That’s the idea behind the influential Technology Acceptance Model (TAM). Here are 10 things to know about the TAM.

Recent Advances with the System Usability Scale

The System Usability Scale (SUS) is the most widely used questionnaire for measuring the perception of usability. It’s been around for more than 30 years. While its original term “system” has fallen somewhat out of favor, its usage has not—with thousands of citations in the literature. The system can be anything from business software, consumer software, websites, mobile apps, or hardware. With such wide usage

Measuring Usability: From the SUS to the UMUX-Lite

Many researchers are familiar with the SUS, and for good reason. It’s the most commonly used and widely cited questionnaire for assessing the perception of the ease of using a system (software, website, or interface). Despite being short—10 items—the SUS has a fair amount of redundancy given it only measures one construct (perceived usability). While some redundancy is good to improve reliability, shorter questionnaires are
