Reuse in hazard analysis: Identification and support

Abstract

This paper investigates the nature of hazard analysis reuse over two case studies. Initially reuse in an existing safety argument is described. Argument structures within the hazard analysis are identified and the amount of verbatim reuse examined. A second study is concerned with how reuse changes as a result of tool support. In contrast to the first case, the defined arguments are more diverse - reuse has occurred but is less verbatim in nature. Tool supported argument adaptation has aided the customisation of the reused arguments. © Springer-Verlag Berlin Heidelberg 2003.
