Tracking User Metrics #2: The Usability Metric for User Experience (Lite)

What is it, how does it work?

The UMUX-Lite survey consists of two simple questions ranked on a scale of 1 to 7.

Similar to the SUS survey, I added a third question asking the users “How could we improve?” that allows me to capture instant feedback and to tag and hierarchize those feedbacks in an aggregation tool, giving me pointers on where I should focus my user research in the future.

Some tips!

  • As for the NPS, clearly indicate your scale: 1 being “Not at all” and 7 being “Totally”. Some users read the scale as inverted, giving them pointers help to avoid false positives.
  • The UMUX-Lite is still being reviewed and tested, it looks like we could also use a 5 points scale which would be easier regarding other ranking systems. As usual for every tool, test on your users, see what works, what doesn’t, and act accordingly.
  • You should always track your UMUX-Lite across time. A single measure doesn’t give you enough to work on, as the UMUX-Lite score might be impacted by a lot of things outside of your control. Track through time, check with your timeline, be mindful of world events.
  • Do not take your user comments at face value, use them to dig a bit more in some area to get a better understanding and more details! Usually, users don’t talk much inside text fields, go to them, explore, and understand.
  • If you use the UMUX-Lite inside your application, do not break your user’s flow! Add it at the end of their experience, track when and where you asked it to be able to frame and correlate it with your global app experience.
  • The original version of the UMUX-Lite uses “requirements” instead of “needs”. However, for some users, it’s complicated to understand. Switching to “needs” makes it easier. If your surveys use words complicated to understand, you will lose some users. Don’t sacrifice your users for survey purity. Improvise, adapt, overcome.

What next?

In the next post, I will talk a bit about how exactly I aggregate, hierarchize and sort some of our user's feedback and how I use them in my day to day work 😉
