Measure the Usability:
To measure the usability we will use the well known System Usability Scale (SUS). We will focus on the all-positive scale from Kortum, P., Acemyan, C. Z., & Oswald, F. L. (2021) rather then the original from Brooke, J. (1986). By asking the related 10 Questions we can get quite fast a measured score.
We will use SUS over Usability Metric for User Experience (UMUX) cause we can get a little more in-depth feedback from users.
Item | Strongly Disagree Strongly Agree | |
|---|---|---|
1 | I think that I would like to use this system frequently. | 1 2 3 4 5 |
2 | I found this system to be simple. | 1 2 3 4 5 |
3 | I thought the system was easy to use. | 1 2 3 4 5 |
4 | I think I could use this system without the support of a technical person. | 1 2 3 4 5 |
5 | I found the various functions in this system were well integrated. | 1 2 3 4 5 |
6 | I thought there a lot of consistency in this system. | 1 2 3 4 5 |
7 | I would imagine that most people would learn to use this system very quickly. | 1 2 3 4 5 |
8 | I found the system very intuitive. | 1 2 3 4 5 |
9 | I felt very confident using the system. | 1 2 3 4 5 |
10 | I could use the system without having to learn anything new. | 1 2 3 4 5 |
To put that score into a intuitive labeling we will use the one from Bangor, Kortum, & Miller (2009):
SUS Score Range | Adjective |
|---|---|
85.59 – 100.00 | Best imaginable |
72.76 – 85.58 | Excellent |
52.02 – 72.75 | Good |
39.18 – 52.01 | OK |
25.01 – 39.17 | Poor |
0.00 – 25.00 | Worst imaginable |

Find treatable problems
By knowing the usability score we already can derive some information. But to better know where exactly the users problem with UI and UX are, we will add more openIMIS related open & closed questions. We should consider to not ask to many so that the churn rate will not be to high.
