We write extensively about standardized UX metrics such as the SUS, PSSUQ, and SUPR-Q. The main benefits of standardization include improved reliability, validity, sensitivity, objectivity, quantification, economy, communication, and norms. Even when standardized UX questionnaires are developed independently, they are influenced by earlier work, just like how UX itself is a new field built upon earlier fields. The deep roots of questionnaire development date back over

We’ve written extensively about the System Usability Scale (SUS). It’s the most widely used and cited questionnaire for measuring the perception of the user experience. But likely the second most widely used and cited questionnaire, with over 2,000 citations, is the Post Study System Usability Questionnaire (PSSUQ). It also goes by the name of Computer System Usability Questionnaire (CSUQ). MeasuringU Press is proud to have

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 it. As part of implementing a plan to improve UX,

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 items are: I think that I would like to use this system frequently. I found the system

The System Usability Scale (SUS) is a popular measure of perceived usability. It's a 10-item questionnaire scored on a 101-point scale and provides a measure of a user’s perception of the usability of a “system.” A system can be just about anything a human interacts with: software apps (business and consumer), hardware, mobile devices, mobile apps, websites, or voice user interfaces. By itself though, the

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

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

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 30 years and because of the wording of the items

Positive word of mouth is a critical driver of future growth for consumer software products. Along with features and capabilities, user experience is a key determinant of how likely users adopt new technology and recommend software. We’ve found that usability accounts for between 30% and 60% of the variation in Net Promoter Scores. A positive experience leads customers to recommend a product. A negative experience,
