One of the more challenging things about learning math in general (and statistics in particular) is how the formulas, often with Greek symbols, translate to things we can see and experience. The abstractness of these formulas often means we just have to take them at face value, believing that someone smarter than us made sure
The System Usability Scale (SUS) is one of the oldest standardized UX questionnaires. John Brooke is now retired; should the questionnaire he developed almost 40 years ago accompany him on the beach with a piña colada? After all, the SUS was developed when there were green-screen computer monitors. How can it possibly apply to mobile
Does better usability lead to more revenue? What about positive word of mouth? Is it tied to revenue growth? Are UX metrics for usability and intent to recommend able to track future revenue growth? Many UX researchers who work for software companies or on software products collect UX metrics. In fact, we strongly advocate for
The System Usability Scale (SUS) has been around for decades and is used by hundreds of organizations globally. The 10-item SUS questionnaire is a measure of a user’s perception of the usability of a “system,” which can be anything from software, hardware, websites, apps, or voice interfaces.

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
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
When I started systematically measuring website usability over 10 years ago I started with the SUS as a key metric. The System Usability Scale (SUS) was the natural questionnaire to start with. It was then, as it is now, a popular 10-item questionnaire to measure the perceived usability of interfaces. It’s been around for over
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 tasks, communication, accounting, and sales.
