A systems-theoretic approach to safety in software-intensive systems

Traditional accident models were devised to explain losses caused by failures of physical devices in relatively simple systems. They are less useful for explaining accidents in software-intensive systems and for nontechnical aspects of safety such as organizational culture and human decision-making. This paper describes how systems theory can be used to form new accident models that better explain system accidents (accidents arising from the interactions among components rather than individual… CONTINUE READING
