The Website Usability Scale (WUS) is a Likert scale-based questionnaire to grade the usability of websites. For each single website usability test our users complete a short questionnaire and we calculate the WUS score from that.
The score is out of 100 and a score of 100 indicates best usability. Some studies have shown websites average a WUS score of 72.
This is what Participants see:
These are the statements:
1. I think that I would like to use this website frequently
2. I found the website unnecessarily complex
3. I thought the website was easy to use
4. I think that I would need the support of somebody technical to be able to use this website
5. I found the various functions in the website were well integrated
6. I thought there was too much inconsistency on this website
7. I imagine that most people would learn to use this website very quickly
8. I found the website very awkward to use
9. I felt very confident using the website
10. I needed to learn a lot of things before I could get going with this website
You can use individual WUS scores to prioritise which test videos to watch first - those with the lowest scores are likely to reveal the biggest problems.
WUS is based on SUS (System Usability Scale). SUS was developed as part of the usability engineering program in integrated office systems development at Digital Equipment Co Ltd., Reading, United Kingdom
