Are you a project manager, business analyst or in a role where you depend on users using software? Then is for you.

  • Find usability problems before you launch to a wider audience
  • Can be used on small sample sizes with reliable results
  • Is valid – it can effectively differentiate between usable and unusable system
  • Simple ten-item questionnaire based on research (System Usability Scale)
  • Requires no expert knowledge to run a survey and understand the result

Find usability problems early helps you conduct a usability survey with people who have used a software product. Many organizations lack in-house user experience specialists and have no resources to hire consultants. Conducting a usability survey with a limited number of users can help you motivate why further research is necessary.

Example scenarios:

  • Evaluating products for inhouse use? Run a survey with your participants to see which is more likely to be used without problems.
  • Rolling out a new version of an application? Run a survey with your trial users before rolling out to everyone.
  • Compare a new version of your software product with the old one

Simple questionnaire

The System Usability Scale (SUS) is a simple, ten-item questionnaire giving a global view of subjective assessments of usability. It was created by John Brooke and has been validated in several research articles.

Having only ten questions means you are likely to get a high number of respondents. The questionnaire has been optimized for mobile devices so responding is possible even on the go.

Requires no expert knowledge

While you can run a System Usability Scale survey in Google Forms or similar tools it is easy to make mistakes when calculating the result and would typically require an expert. can be used by people who aren’t UX experts.

The System Usability Scale - based on research

SUS has become an industry standard, with references in over 1300 articles and publications. It consists of a 10 item questionnaire with five response options for respondents; from Strongly agree to Strongly disagree. Originally created by John Brooke in 1986, it allows you to evaluate a wide variety of products and services, including hardware, software, mobile devices, websites and applications.
