ABSTRACT
A HF problem will more than likely possess some, or all, of the following attributes. It will be a problem that impacts negatively on individual behavior and overall system performance. It will involve humans in systems not behaving as they were expected to because elements of the system were not designed to fit their needs and capabilities. These elements include the artifacts they are using, the physical environment, the training they have received, the procedures they are working too, and the other humans they are interacting with, and so on.
