Document Summary
Dynamics of accident causation: accident are caused by an interplay of later errors, active errors, triggering events & failure of defense systems. Management cuts lunch breaks > driver eats while driving > snowing > defense systems fail > accident. The irony of automation: humans are unreliable, irritable & inefficient. But: in situations too hard to automate, the unreliable human is expected to take over, if humans are substituted by tech systems. Long term loss of competence to control the process. Useability criterion (jakob nielsen: ease of learning. Interface needs to allow users who have never seen it before to learn quickly: efficiency of use. Interface needs to be designed to allow rapid accomplishment of tasks for experienced users: memorability. Casual users assisted by interface design that they can rmb how to use: error prevention. Interface designed to minimize no. of & severity of errors for quick recovery: subjective satisfaction.
