You know that usability is critical to your conversion rate, so you probably put a lot of effort into making sure your visitors stay on your website instead of leaving for your competitor\u2019s. But you may not know about a UX research tool that quantifies and normalizes user feedback to make meaningful comparison of usability data easy.<\/p>\n

The System Usability Scale<\/a> is a widely respected questionnaire that consolidates and unifies the subjective responses of individual UX testers into a coherent description of a site\u2019s strengths and inadequacies. Something of an industry standard in usability research today, this \u201cquick and dirty\u201d survey has long been a favorite for its simplicity and accuracy: ten questions, a five-point \u201cstrongly agree\u201d to \u201cstrongly disagree\u201d response system, and a quick scoring algorithm yield an extremely reliable usability score on a scale of 0 to 100.<\/p>\n

    \n
  1. I think that I would like to use this system frequently.<\/li>\n
  2. I found the system unnecessarily complex.<\/li>\n
  3. I thought the system was easy to use.<\/li>\n
  4. I think that I would need the support of a technical person to be able to use this system.<\/li>\n
  5. I found the various functions in this system were well integrated.<\/li>\n
  6. I thought there was too much inconsistency in this system.<\/li>\n
  7. I would imagine that most people would learn to use this system very quickly.<\/li>\n
  8. I found the system very cumbersome to use.<\/li>\n
  9. I felt very confident using the system.<\/li>\n
  10. I needed to learn a lot of things before I could get going with this system.<\/li>\n<\/ol>\n
    \"SUS<\/div>\n
    <\/div>\n

    With thousands of previously documented uses to compare to, SUS gives you a solid idea of users\u2019 overall satisfaction with your website, and can even be broken down into usability and learnability components. The percentile ranking contextualizes your raw score, allowing you to understand how your site performs relative to others; and some researchers have tried, with some success, to map adjectives like \u201cexcellent,\u201d \u201cpoor,\u201d or \u201cworst imaginable\u201d to individual scores for extra insight.<\/p>\n

    \"SUS<\/div>\n
    <\/div>\n

    By various accounts, the mean SUS score hovers around 68-70.5 (a score that roughly corresponds, as it happens, to the adjective \u201cgood,\u201d though falling quite short of \u201cexcellent\u201d). Normalizing score distribution with percentiles therefore makes a 68 (or a 70.5) into a 50% – better than half of all other systems tested, and worse than the other half.<\/p>\n

    Though described by its inventor as a \u201cquick and dirty\u201d measure, studies have found SUS to be among the most accurate and reliable<\/a> of all usability surveys, across sample sizes. It has today become one of the most successful metrics for quantifying system satisfaction, with thousands using it to gauge user-friendliness over a wide range of products online and off.<\/p>\n

    It is these qualities that make SUS key for staying on the competitive edge of UX design. If individual test videos are the trees, SUS shows you not only the forest, but the entire ecosystem into which your site fits; with a widely-trusted industry standard to rely on, you can take a step back from your own company and see how you chalk up in the broader world of competing websites that surrounds you.<\/p>\n
