[edit] Abstract
Techniques developed for hardware reliability and safety do not work on software-intensive systems. This is because software does not satisfy the assumptions underlying these techniques. The new problems and why the current approaches are not effective for complex, software-intensive systems are described in the first part of the article. A new approach to hazard analysis and safety-driven design is then presented. Rather than being based on reliability theory, as most current safety engineering techniques are, the new approach builds on system and control theory.
