The use of fault reporting of medical equipment to identify latent design flaws
Human factors methods were used to investigate No Fault Found (NFF) incidents. Medical equipment maintenance data was used to identify devices with high NFF rates. Interviews and heuristic analyses revealed usability issues cause NFF incidents. Usability testing validated the results. Our methodology can be used to identify devices with usability related design flaws.
