We recently worked on a project that focused on the replacement of a medical case management system. Early in our user research we used the System Usability Scale (SUS) to evaluate the existing system. The SUS score of that system was 44.5 out of possible 100 (the average score is 68). The system was so poorly designed that during one user interview a nurse began to cry as she described the various tasks she was required to complete in order to track patients and document her interactions with them.

As the outdated system was slowly replaced with a new system that increasingly incorporated data analytics and artificial intelligence, the SUS scores improved. The synergistic use of AI and analytics led to the development of a richer experience, and the SUS scores improved by more than 100%, jumping to 93.
