What does this system measure?

It measures the perceived usability level of a product. System Usability Scale (SUS) is one of the most efficient ways of gathering statistically valid data and giving your app/site a clear and reasonably precise score. For instance, SUS might be 52 (poor).

Such a low score indicates an issue and the feedbacks from the survey will help to find out what exactly goes wrong with the website or app.

How will it help for a business?

“Design can drive exceptional returns for shareholders”.

Tracking SUS in a regular basis helps a business:

  • To keep an eye on user’s UX satisfaction.
  • To prevent a business from the destructive consequences of any design issues.
  • To set a clear metric for a design or a product team.

Do I need real customers to measure SUS?

Yes. You need to have at least 5 active users to run one survey.

How may I send a link to users?

You can send your request via email, chat or any other system like MailChimp, Intercom, Sendgrid, Mixpanel etc. Just copy a link, take our draft of a message and send it to your 20 active users.
