Cognitive systems engineering described

The current literature in the areas of cognitive engineering, error analysis, and human-computer interaction contains many models, descriptions, methodologies, metaphors, and functional analogies. However, in this chapter we are not focusing on the models of these individual elements of human behavior but rather on models that can be used to describe human performance in systems. These human/system performance models typically include some of these elemental behavioral models as components but provide a structural framework that allows them to be put in the context of human performance of tasks in systems.
